NOTE
This Code is produced in terms of Section 3 of the
Agriculture (Miscellaneous Provisions) Act 1968 (1968
c.34).
This Section allows the Scottish Ministers, after
consultation, to prepare codes of recommendations for the
welfare of livestock.
This Code was laid before Parliament as is required
by Section 3 of the above Act.
The power to produce these codes was transferred to
the Scottish Ministers by virtue of Section 53 of the
Scotland Act 1998 (1998 c.46).
Any reference in this Code to advisory publications
is for information only and does not form part of this
Code.

preface
This preface is not part of the Code but is intended to
explain its purpose and to indicate the broad
considerations upon which it is based. Similarly, the
legislation quoted in boxes throughout the document is not
part of the Code but is intended to highlight some of the
legal requirements. The law, as quoted in these boxes, is
that in force either on the date of publication or
reprinting of the Code (please turn to the back cover for
this information). Readers should be aware that any of the
legal requirements quoted might be subject to change - they
should seek confirmation before assuming that these are an
accurate statement of the law currently in force.
Regulation 10 of the Welfare of Farmed
Animals (Scotland) Regulations 2000 (S.S.I.
2000 No. 442), as amended, provides that: - Any person who employs or engages a
person to attend to animals must ensure
that the person attending to the
animals
- is acquainted with the provisions of
all relevant statutory welfare codes
relating to the animals being attended
to;
- has access to a copy of those codes
while that person is attending to the
animals; and
- has received instruction and guidance
on those Codes.
- Any person who keeps animals, or who
causes or knowingly permits animals to be
kept, must not attend to them unless that
person has access to all relevant statutory
welfare codes relating to the animals while
that person is attending to them, and is
acquainted with the provisions of those
codes.
In Regulation 2 it states that "statutory
welfare code" means a code for the time being
issued by Scottish Ministers under Section 3 of
the Agriculture (Miscellaneous Provisions) Act
1968[3]. To cause unnecessary pain or unnecessary
distress to any livestock on agricultural land
is an offence under Section 1(1) of the
Agriculture (Miscellaneous Provisions) Act
1968. The breach of a code provision, whilst
not an offence in itself, can nevertheless be
used in evidence as tending to establish the
guilt of anyone accused of causing the offence
of causing unnecessary pain or distress under
the Act (Section 3(4)). |
Regulation 3(1) of the Welfare of Farmed
Animals (Scotland) Regulations 2000 (S.S.I.
2000 No. 442), as amended, states that owners
and keepers of animals must take all reasonable
steps: - to ensure the welfare of the animals
under their care; and
- to ensure that the animals are not
caused any unnecessary pain, suffering
or
- injury.
|
Regulation 3(3) of the Welfare of Farmed
Animals (Scotland) Regulations 2000 (S.S.I.
2000 No. 442), as amended, states that: - In deciding whether the conditions
under which animals are being bred or kept
comply with the requirements set out in
Schedule 1 of the Regulations, the owner
and keeper of the animals must have regard
to their species, and to their degree of
development, adaptation and domestication,
and to their physiological and ethological
needs in accordance with established
experience and scientific knowledge.
Regulation 11 of the Welfare of Farmed
Animals (Scotland) Regulations 2000 (S.S.I.
2000 No. 442), as amended, states that: - Where an authorised person considers
that animals are being kept in a way which
is likely to cause unnecessary pain,
suffering or injury, or in any way in
contravention of any provision of these
Regulations, the authorised person may
serve a notice on whoever appears to be in
charge of the animals requiring the person
appearing to be in charge, within the
period stated in the notice, to take any
action that the authorised person considers
to be reasonably necessary to ensure
compliance with these Regulations and the
authorised person must give his reasons for
requiring that action to be taken.
|
Regulation 13(2) of the Welfare of Farmed
Animals (Scotland) Regulations 2000 (S.S.I.
2000 No. 442), as amended, states that: - In any proceedings against an owner or
keeper for a failure to comply with
Regulation 3(1) or 3(2) (as read with
Regulation 3(3) the owner or keeper as the
case may be, may rely on compliance with
any relevant recommendation contained in a
statutory welfare code, as tending to
establish compliance with the relevant
Regulation.
|
The Code is intended to encourage all those who care for
farm animals to adopt the highest standards of husbandry.
Without good stockmanship, animal welfare can never be
adequately protected. Adherence to these recommendations
will help flock-keepers to reach the required standard.
The welfare of meat chickens and breeding chickens is
considered within a framework, elaborated by the Farm
Animal Welfare Council, and known as the 'Five
Freedoms'. These form a logical basis for the
assessment of welfare within any system together with the
actions necessary to safeguard welfare within the
constraints of an efficient livestock industry.
The Five Freedoms are:
1
Freedom from hunger and thirst - by ready
access to fresh water and a diet to maintain full health
and vigour;
2
Freedom from discomfort - by providing an
appropriate environment including shelter and a comfortable
resting area;
3
Freedom from pain, injury or disease - by
prevention or rapid diagnosis and treatment;
4
Freedom to express most normal behaviour -
by providing sufficient space, proper facilities and
company of the animals' own kind;
5
Freedom from fear and distress - by
ensuring conditions and treatment which avoid mental
suffering.
In acknowledging these freedoms, those who have care of
livestock should practise:
- caring and responsible planning and
management;
- skilled, knowledgeable and conscientious
stockmanship;
- appropriate environmental design (for example of
the husbandry system);
- considerate handling and transport;
- humane slaughter.
The Protection of Animals (Scotland) Act 1912, as
amended, contains the general law relating to cruelty to
animals. Broadly it is an offence (under Section 1 of the
1912 Act) to be cruel to any domestic or captive animal by
anything that is done or omitted to be done.
Section 11(2) of the 1912 Act empowers a police
constable to place in safe custody, animals in the charge
of persons apprehended for an offence under the Act until
the end of proceedings or the court orders the return of
the animals. The reasonable costs involved, including any
necessary veterinary treatment, are recoverable by the
police from the owner upon conviction.
Under section 1 of the Protection of Animals (Amendment)
Act 1954, as amended by the 1988 Act, the court has the
power to disqualify a person convicted under these Acts
from having custody of any animal. The ban can specify a
particular kind of animal or all animals for such period as
the court thinks fit. Where such a ban is imposed, the
court can suspend the disqualification for such period as
it thinks necessary to allow the person time to enable him
to make suitable arrangements for the custody of any
animals to which the disqualification relates.
This Code applies in Scotland only and has been issued
by the Scottish Ministers (following approval in draft by
the Scottish Parliament). It replaces (also as regards
Scotland only) that part of the existing Domestic Fowls
Code (issued in 1987), relating to the welfare of meat
chickens and breeding chickens.
Similar Codes are being produced in England, Wales and
Northern Ireland. Until these new Codes are issued, the
existing provisions in the Domestic Fowls Code will
continue to apply in England and Wales. Separate
arrangements exist in Northern Ireland.
introduction
Code for the welfare of meat chickens and
breeding chickens
1 This Code (which applies in Scotland
only) applies to all parts of the meat chicken production
sector, including breeding birds and grandparent stock. For
the purposes of the code "flock-keeper" means the owner of
the birds or the person responsible for looking after them.
The recommendations are relevant to meat chickens and
breeding chickens under all types of husbandry system.
Following them will help to ensure that the welfare of the
birds is safeguarded.
2 No person should operate or set up a
meat chicken or breeding chicken unit unless the welfare of
all the birds can be safeguarded. This can be achieved by
ensuring that the building and equipment, and the skills
and ability of the flock-keeper, are appropriate to the
husbandry system and the number of birds to be kept.
3 The relevant animal welfare legislation
applies to owners as well as any person looking after the
chickens on their behalf, wherever the chickens are
located. A written contract can be of value in ensuring
that all parties are clear about their responsibilities in
respect of welfare. However, the obligations imposed by the
law will still apply.
4 The strain of bird selected must be
suitable for the production system. In particular, care
must be taken in the production of chicken with extended
growing periods (
e.g. organic, free range) to use suitable
strains and feeding regimes.
stockmanship and
staffing
Schedule 1, paragraph 1 of the Welfare of
Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states
that: - Animals must be cared for by a
sufficient number of staff who possess the
appropriate ability, knowledge and
professional competence.
|
5 It is essential that sufficient,
well-motivated and competent personnel be employed to carry
out all necessary tasks. Staff should be well managed and
supervised, fully conversant with the tasks they will be
required to undertake and competent in the use of any
equipment.
6 All flock-keepers should have
demonstrated full understanding of the welfare needs and
basic biology of the birds and have shown that they are
capable of safeguarding them under all foreseeable
conditions before being given responsibility for a flock. A
good flock-keeper will have a compassionate and humane
attitude, will be able to anticipate and avoid many
potential welfare problems, and have an ability to identify
those that do occur and respond to them promptly.
7 Staff, including those employed by
contractors, should be given appropriate training. This
requires the acquisition of specific stockmanship skills,
which may be developed on-farm, working with an experienced
person, or by following a course offered by a suitable
training provider. Flock-keepers should demonstrate
competence and understanding before they are given
responsibility for the birds. Training should continue
throughout the duration of employment, and suitable
refresher courses should be undertaken regularly. Wherever
possible, the training should be of a type that leads to
formal recognition of competence.
8 A training plan should be implemented to
ensure that those working with meat chickens or breeding
chickens recognise not only normal behaviour and good
health but also signs of illness or disease or impending
health problems. If specialised tasks are to be performed,
for example vaccination or humane culling, then specific
training should be given. Alternatively, the services of a
competent contractor using trained staff should be
obtained.
9 Staff should establish a methodical
routine in completing the range of tasks involved in
keeping chickens. As part of this they should be
particularly vigilant in checking that systems are
operating properly and birds are behaving normally. This
will enable flock-keepers to detect problems in their
earliest stages and acquire a good understanding of the
action to be taken if a problem is noticed. If the cause is
not obvious, or if the flock-keeper's action is
not effective, immediate veterinary or technical advice
should be obtained.
10 It is essential to
ensure that enough time is available within the
flock-keeper's daily work routine for the birds to
be properly inspected and for any remedial action to be
taken. Large flocks can be managed successfully but in
general the larger the size of unit, the greater the degree
of skill and dedication needed to safeguard the welfare of
the birds.
feed and water
Schedule 1, paragraphs 22-27 of the Welfare
of Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states
that: - Animals must be fed a wholesome diet
which is appropriate to their age and
species and which is fed to them in
sufficient quantity to maintain them in
good health, to satisfy their nutritional
needs and to promote a positive state of
well-being.
- Animals must not be provided with food
or liquid in a manner, nor must such food
or liquid contain any substance, which may
cause them unnecessary suffering or
injury.
- All animals must have access to feed at
intervals appropriate to their
physiological needs (and, in any case at
least once a day) except where a veterinary
surgeon acting in the exercise of his
profession otherwise directs.
- All animals must either have access to
a suitable water supply and be provided
with an adequate supply of fresh drinking
water each day or be able to satisfy their
fluid intake needs by other means.
- Feeding and watering equipment must be
designed, constructed, placed and
maintained so that contamination of food
and water and the harmful effects of
competition between animals are
minimised.
- Only substances given for therapeutic
or prophylactic purposes or for the purpose
of zootechnical treatment may be
administered to animals unless it has been
demonstrated by scientific studies of
animal welfare or established experience
that the effect of that substance is not
detrimental to the health or welfare of the
animals.
|
11 All birds should have daily access to
feed. When introducing birds to a new environment, the
flock-keeper should ensure that the birds can find feed and
water.
12 To prevent birds having access to stale
or contaminated feed or water these should be replaced on a
regular basis. Provision must be made for supplying water
in freezing conditions.
13 In intensively housed systems, the
maximum distance which any bird should have to travel in a
house to reach feed and water should not be more than 4
metres. However, in some situations, such as some outdoor
production systems, it may be necessary for the birds to
travel more than 4 metres; in these situations, all birds
must be adequately cared for in terms of stocking density,
feeding and drinking space to allow for such movements.
14 Sudden changes in the type and quantity
of feed should be avoided. Any changes in diet should be
introduced gradually.
15 Compounded feeds which have been
prepared for other species should be avoided as certain
substances can be toxic to birds.
16 For meat chickens, feed should not be
withheld for more than 12 hours before the birds are
slaughtered or delivered to a new farm. This period of 12
hours must be an inclusive period to include the catching,
loading, transport, lairaging and unloading time prior to
slaughter. Prior to transport, water should be provided up
to the start of the loading procedure (
see paragraph 86 for specific
provisions for breeding chickens).
17 Water meters should be fitted to each
house to enable daily monitoring of water usage. Daily
records of water consumption provide an early warning of
potential problems and a water meter is a necessary
management tool.
18 Daily access to water throughout the
period of lighting and a sufficient number of drinkers,
well distributed and correctly adjusted, should be
provided.
health
inspection
Schedule 1, paragraph 2 of the Welfare of Farmed Animals
(Scotland) Regulations 2000 (S.S.I. 2000 No. 442), as
amended, requires that:
- All animals kept in husbandry systems in which
their welfare depends on frequent human attention must
be thoroughly inspected at least once a day to check
that they are in a state of well-being and:
- Animals kept in systems other than husbandry
systems in which their welfare depends on frequent
human attention must be inspected at intervals
sufficient to avoid any suffering.
Schedule 1, paragraph 3 states that:
Where animals are kept in a building, adequate lighting
(whether fixed or portable) must be available to enable
them to be thoroughly inspected at any time.
19 In order to reduce the risk of welfare
problems developing on meat chicken or breeding chicken
units, it is recommended that a systematic inspection of
all flocks should be undertaken at least twice each day at
appropriate intervals. Young birds, in the first few days
of life, should be inspected more frequently.
20 These health and welfare inspections
may be linked with other visits to the poultry houses but
each inspection should be undertaken as a separate,
specific procedure.
21 Flock-keepers should establish in
advance the best course of action to take should problems
be identified and ensure that veterinary or other expert
advice is available when needed.
22 Light levels during inspection should
be sufficiently high to ensure that all birds in all parts
of the house are clearly visible.
23 While it may not be possible to examine
each bird individually during routine inspection a good
indication of flock health should be gained on each
occasion. Where birds are not being fed on ad lib diets,
inspection is particularly effective at feeding time when
any birds, which are not fit, will be slow to feed and can
be identified.
24 In order to ensure a thorough
inspection the flock-keeper should walk within 3 metres of
every bird and encourage it to move, taking care not to
frighten the birds with sudden, unaccustomed movement,
noise or changes in light levels. The aim should be to pass
close enough to the birds to see them clearly and for them
to be disturbed and so move away. This should enable the
identification of any individual that is sick, injured or
weak. Any such birds should, immediately, be removed to a
hospital pen and treated, or humanely killed. Birds with
considerable difficulty in walking, severe ascites,
malformations, severe wounds or seizures should be culled
immediately unless they can be treated and are likely to
recover without unnecessary suffering. Dead birds should be
removed without delay.
It is a general offence under the Welfare of Animals
(Slaughter or Killing) Regulations 1995 (S.I. 1995 No. 731)
as amended by the Welfare of Animals (Slaughter or Killing)
(Amendment) Regulations 1999 (S.I. 1999 No. 400) and the
Welfare of Animals (Slaughter or Killing) (Scotland)
(Amendment) Regulations 2000 (S.S.I. 2001 No. 145) to cause
or permit any avoidable excitement, pain or suffering to
any animal (bird) during the slaughter or killing process
(Regulation 4(1)). The general offence applies in all
cases, but the detailed provisions in respect of the method
of slaughter or killing do not apply when an animal (bird)
has to be killed immediately for emergency reasons
(Regulation 13(2)).
When an animal (bird) is routinely slaughtered or killed
on farm, this must be done using a permitted method. The
permitted methods of killing poultry include decapitation
and neck dislocation.
disease control
Schedule 1, paragraph 5 of the Welfare of
Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states that
any animals which appear to be ill or
injured: - must be cared for appropriately without
delay; and
- where they do not respond to such care,
veterinary advice must be obtained as soon
as possible
Schedule 1, paragraph 6 states: - Where necessary, sick or injured
animals must be isolated in suitable
accommodation with, where appropriate, dry
comfortable bedding.
|
25 A health and welfare programme should
be implemented for each unit which sets out health and
husbandry activities covering the whole of the production
cycle. It should also establish management procedures and
control measures to reduce the risk of infections and
injury. This will normally include an effective vaccination
protocol (which should be carefully monitored to ensure
efficacy) to reduce the risk of disease outbreaks. The
health and welfare programme should be developed with
appropriate veterinary advice and reviewed against
performance and updated accordingly.
26 Important indications of good health
are clear, bright eyes, alertness, good posture, vigorous
movements if unduly disturbed, active feeding and drinking,
singing and vocalisation, satisfactory egg production in
the case of breeding chickens, and clean and healthy skin,
shanks and feet. Any departure from the norm may indicate a
problem which should be given immediate attention.
27 A disease challenge may be first
noticed by a change in water consumption or a reluctance to
eat, changes in litter quality or in general behaviour of
the flock. It is, therefore, good management practice to
keep daily records of water consumption and where possible,
feed intake. Veterinary attention should be sought at an
early stage in any outbreak of disease so that the cause
can be determined and appropriate action taken.
28 Measures to control diseases caused by
external parasites should be taken by using the appropriate
parasiticides. It is particularly important to take
measures to prevent the establishment of red mite
infestation in breeding chicken flocks; these measures must
not cause harm to the birds.
29 Should the flock-keeper decide that
there is a good chance of a sick bird recovering, it should
be isolated in a hospital pen, providing it is able to eat,
drink and stand unassisted. Birds should be examined
frequently throughout the day. However, if a bird is
suffering and cannot be treated or if it fails to show
significant improvement within 24 hours of being placed in
the hospital pen it should be humanely killed without
delay.
30 All those in contact with birds should
practise strict hygiene and disinfection procedures. Where
possible the site should be managed so that all houses are
empty simultaneously to facilitate effective cleaning,
disinfection and disinfestation. An "all in - all out"
approach with periods when there are no birds on site will
also act to provide a disease break.
31 When houses are emptied and cleaned,
old litter should be removed from the site before
re-stocking so as to reduce the risk of the carry over of
disease.
leg health
32 Flock-keepers should monitor all birds
for signs of lameness, leg weakness or abnormal gait on a
daily basis. Any bird, which is unable to move about freely
and find feed and water, must be humanely killed as soon as
it is detected unless it can be treated and is likely to
recover without unnecessary suffering.
33 Management measures should be taken to
prevent lameness, having regard to previous experience on
the farm and recognised best practice. The strain and
source of chicks, stocking density, lighting patterns, feed
composition and feeding routine and litter management
should all be considered. Lameness is often caused by a
bone or joint infection so effective prevention and control
of viral and bacterial disease is essential. If a lameness
problem develops, management and husbandry practices must
immediately be altered as appropriate in order to rectify
the problem. Encouraging activity will help prevent the
occurrence of leg problems.
34 Chickens can suffer from lameness due
to infections acquired in the parent flock or hatchery. It
is believed that 60% of lameness cases result from
infectious causes. High standards of biosecurity and
hygiene in the handling of the eggs, at the hatchery and in
subsequent handling and transport of the chicks should be
maintained. Husbandry measures should be designed to
minimise floor eggs and heavily soiled eggs should not be
set as hatching eggs.
mutilations
general
The Welfare of Livestock (Prohibited
Operations) Regulations 1982 (S.I. 1982
No.1884) state that the following are
prohibited operations: - devoicing of cockerels
- castration of male birds by a method
involving surgery
- any operation on a bird with the object
of impeding is flight, other than feather
clipping
- fitting of any appliance which has the
object or effect of limiting vision to a
bird by a method involving the penetration
or other mutilation of the nasal
septum
De-winging, pinioning, notching or tendon
cutting are prohibited under the above
Regulations, as they involve the mutilation of
wing tissue. When it is necessary to reduce the
effect of flightiness, the flight feathers of
one wing may be clipped. The use of blinkers which pierce the nasal
septum is prohibited. Other forms of device
fitted to birds' heads (such as spectacles,
contact lenses and nasal bits) may also cause
welfare problems and should not be used. |
35 Mutilations can cause considerable pain
and therefore constitute a major welfare insult to farm
animals. They are undesirable in principle and should only
be carried out where it is necessary to avoid a worse
welfare problem. Producers should consider carefully the
necessity of performing
any mutilation. Where deemed necessary mutilations
should be carried out humanely, in accordance with the law
and by trained, competent staff. High standards of hygiene
are essential.
beak trimming
When not carried out by a veterinary surgeon
beak-trimming must be carried out in accordance
with the Veterinary Surgery (Exemptions) Order
1962 (S.I. 1962 No. 2557)
i.e. The operation of
beak-trimming (sometimes known as debeaking)
means the removal from a bird by means of a
suitable instrument of (i) not more than a one-third part of its
beak, measured from the tip towards the
entrance of the nostrils, if carried out as a
single operation; or (ii) not more than a one-third part of its
upper beak only, measured in the same way; and the arrest of any subsequent haemorrhage
from the beak by cauterisation. |
36 Beak trimming of birds reared for meat
should not be necessary because they are normally
slaughtered before reaching sexual maturity. Beak trimming
of broiler breeders should be avoided, if at all possible,
and used only if veterinary advice is that the procedure is
essential to prevent worse welfare problems of injurious
feather pecking and cannibalism. Consideration should be
given to environmental enrichment as a means of avoiding
the necessity to beak trim; possible methods of
environmental enrichment include the provision of straw
bales or brassicas or scattering of whole grain.
37 It is unnecessary to
beak trim female breeding chicks and only the tip of the
beak should be removed from male breeding chicks. This is
best done at 5 to 10 days of age in order to allow the
chicks to establish eating and pecking behaviours before
the operation takes place. Beak trimming of older birds
should only be carried out when advised by a veterinary
surgeon.
dubbing
The Veterinary Surgeons Act 1966 (Schedule 3
Amendment) Order 1988 (S.I. 1988 No 526)
permits only a veterinary surgeon to remove the
combs or to cut the toes of a domestic fowl
which has reached the age of 72 hours. On birds
younger than 72 hours the operations may be
carried out by unqualified persons (those over
18 years of age) using a suitable instrument.
The removal of the dependent portion of a
bird's wattles may also be removed by
unqualified persons using a suitable
instrument. |
38 The removal of all, or part, of the
male comb is known as dubbing. Removal of the comb offers
few, if any, welfare advantages in comparison with the
disturbance and pain likely to be caused and should be
avoided. Where the operation occurs, it is usually
performed when the chicks are one day old using sharp
scissors and should only be undertaken by appropriately
trained personnel. Once chicks are over 72 hours old, the
procedure must only be carried out by a veterinary surgeon:
this is a requirement of law.
despurring
39 This is the removal, at day-old, of the
spur bud on the back of the male's leg using a
heated wire. If the spur grows to be very pronounced it may
cause damage to females during mating. Selection of
breeding male stock with the genotype of short, blunt spurs
should be encouraged, so that routine despurring should not
be necessary.
declawing
40 Some parts of the industry remove the
dew and pivot claw from the feet of breeding males to
prevent damage to females during natural mating. The
procedure is usually carried out at day-old and must be
carried out by a trained, competent person. It is more
common to remove only the dewclaws as these cause
significantly more damage than the pivot claws. The removal
of the pivot claw has little justification in welfare terms
and should be avoided.
toe removal
41 This mutilation is controlled by law (
see box following paragraph
37). Toe removal (cutting) for purposes of
identification is an unnecessary mutilation and should be
avoided. Instead alternative methods of identification
should be used that do not adversely affect the
chicks' welfare.
building and
accommodation
Schedule 1, paragraphs 11 and 12 of the
Welfare of Farmed Animals (Scotland)
Regulations 2000 (S.S.I. 2000 No. 442), as
amended, state that: - Materials used for the construction of
accommodation, and, in particular for the
construction of pens, cages, stalls and
equipment with which the animals may come
into contact, must not be harmful to them
and must be capable of being thoroughly
cleaned and disinfected.
- Accommodation and fittings for securing
animals must be constructed and maintained
so that there are no sharp edges or
protrusions likely to cause injury to
them.
|
general
42 Advice on welfare aspects should be
sought before any new buildings are constructed or existing
buildings modified. It is important to ensure that the
design of housing and equipment is suitable for the
intended use. The incorporation of facilities for raising
drinkers and feeders to aid access for handling equipment
should be considered. Consideration should also be given to
the incorporation of weighing, handling and loading
facilities.
43 Flock-keepers should take measures to
protect birds from predators, rodents and other animals.
Further advice on the control of vermin can be found in
DEFRA Code of Practice for the
Prevention of Rodent Infestations in Poultry Flocks -
see Appendix 1.
ventilation and
temperature
Schedule 1, paragraph 13 of the Welfare of
Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states
that: - Air circulation, dust levels,
temperature, relative air humidity and gas
concentrations must be kept within limits
which are not harmful to the animals.
|
44 Ventilation rates and house conditions
should at all times be adequate to provide sufficient fresh
air for the birds and keep the litter dry and friable. Air
quality, including dust level and concentrations of carbon
dioxide, carbon monoxide and ammonia, should be controlled
and kept within limits where the welfare of the birds is
not negatively affected. In particular, the concentration
of ammonia should not exceed 20ppm of air measured at bird
height level.
45 Extremes of temperature should be
avoided. Maximum and minimum temperatures should be
monitored and recorded daily to assist management. Birds
should be protected from cold draughts. Efforts should be
made to ensure that the ventilation systems do not result
in large differences in air speed across the house.
46 Chicks should be placed in the brooding
area when they arrive in the house and their behaviour
monitored carefully. Young chicks are particularly
susceptible to extremes of temperature and an even
distribution of the chicks in the house will indicate that
they are comfortable. After 4-5 weeks birds can tolerate a
fairly wide range of temperatures but every effort should
be made to avoid creating conditions which will lead to
chilling, huddling and subsequent smothering.
47 Birds on restricted feed are more
susceptible to low temperatures but less so to high
temperatures. If the temperature is allowed to fall there
may be a need to increase feed or provide heaters.
heat stress
48 Birds should not be exposed to strong,
direct sunlight or hot, humid conditions long enough to
cause heat stress as indicated by prolonged panting.
Housing affects the birds' ability to maintain
their normal body temperature but under any management
system ambient temperatures high enough to cause prolonged
panting may occur, particularly when humidity is relatively
high. All accommodation should therefore be designed so
that its ventilation is adequate to protect the birds from
overheating under any weather conditions that can
reasonably be foreseen. Attention should be paid to air
throughput and distribution, especially at bird level.
49 Flock-keepers should plan ahead to
avoid heat stress. During the summer months consideration
should be given to reducing stocking density at the time of
ordering or placing day-old chicks. If suffering or
mortality occurs, the onus will be on the person
responsible for the birds to demonstrate that the measures
taken were appropriate for the design of the building, its
locality and the predictable maximum temperature/humidity
at the time.
50 During hot and humid conditions, the
birds should be checked frequently, but not disturbed
unduly.
51 Steps should be taken to minimise the
potential for heat stress by increasing ventilation and air
speed at bird level. Portable back-up fans should be
available. The air temperature within a building may be
reduced by improved insulation, hosing the roof and the
correct use of evaporative cooling of incoming air. The
heat output of the birds may be reduced by lowering
stocking density or changing the feeding patterns. Advice
about management measures to prevent heat stress is given
in a
DEFRA booklet "Heat Stress in Poultry"-
see Appendix 1.
lighting
Schedule 1, paragraphs 14-16 of the Welfare
of Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states
that: - Animals kept in buildings must not be
kept in permanent darkness.
- Where the natural light available in a
building is insufficient to meet the
physiological and ethological needs of any
animals being kept in it then appropriate
artificial lighting must be provided.
- Animals kept in buildings must not be
kept without an appropriate period of rest
from artificial lighting.
|
52 Chickens should be housed at light
levels allowing them to see clearly and which stimulate
activity. This should be provided by lighting systems
designed, maintained and operated to give a minimum light
level of 10 lux at bird eye height. Illumination of the
house to at least 20 lux will further encourage activity.
Houses should have a uniform level of light. If a
behavioural problem such as cannibalism occurs, it may be
necessary to dim the lights for a few days.
53 Meat chickens, which do not have access
to daylight, should be given at least 8 hours of artificial
lighting each day. It is important for bird welfare to
provide them with a period of darkness (not less than 30
minutes) in each 24-hour cycle. This ensures the birds
become used to total darkness and helps to prevent panic in
the event of a power failure. Longer periods of darkness
can reduce mortality and improve leg health.
litter
Schedule 3 of the Welfare of Farmed Animals
(Scotland) Amendment Regulations 2002 (S.S.I.
2002 No.334) states that: - Where any poultry (other than those
kept in the systems referred to in
Schedules 3A, 3B and 3C) are kept in a
building, they must be kept on, or have
access at all times to, well maintained
litter or to a well-drained area for
resting.
|
54 Meat chickens and breeding chickens
spend their lives in contact with litter and their health
and welfare are linked to its quality. Conditions such as
pododermatitis, hock burn, foot pad lesions and breast
blisters are consequences of poor litter quality.
Well-designed equipment and high standards of management
are important if good litter quality is to be maintained.
The ventilation capacity should be sufficient to avoid
overheating and to remove excess moisture. The feed
composition should be well balanced to avoid problems with
wet or sticky droppings.
55 Litter should be kept loose and friable
and measures should be taken to minimise the risk of mould
and mite infestation. It should be inspected frequently for
signs of deterioration and appropriate action should be
taken to rectify any problem. Mouldy litter should not be
used. Litter should also be inspected to ensure it does not
become excessively wet or dry. A water system which
minimises water spillage should be used, such as water
nipples with drip cups positioned at an appropriate height
for all birds. Nipple drinkers without cups may be used if
they are well managed and the water pressure is checked
frequently. Advice on litter management is given in a
DEFRA booklet - " Poultry Litter
Management" -
see Appendix 1 - and
flock-keepers should familiarise themselves with this
advice.
emergency procedures
56 Farmers should make advance plans for
dealing with emergencies such as fire, flood, power or
equipment failure or disruption of supplies, and should
ensure that all staff are familiar with the appropriate
emergency action. At least one responsible member of the
staff should always be available to take the necessary
steps. Fire precautions should be a major priority for all
flock- keepers. Where buildings need to be locked,
arrangements must be made to allow rapid entry in case of
emergency.
57 Flock-keepers should have access to and
be familiar with the content of the
DEFRA booklet "Farm Fires" -
see Appendix 1. Expert
advice on all fire precautions can be obtained from fire
prevention officers of local fire brigades and from the
Fire Prevention Association.
58 Contingency arrangements should be made
to ensure that adequate supplies of water and suitable feed
can be made available in emergencies. Efforts should be
made to minimise the risk of drinking water freezing.
stocking density-freedom of
movement
Schedule 1, paragraph 9 of the Welfare of
Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states
that: - The freedom of movement of animals,
having regard to their species and in
accordance with established experience and
scientific knowledge, must not be
restricted in such a way as to cause them
unnecessary suffering or injury;
- Schedule 1, paragraph 10 states
that:
- Where animals are continuously or
regularly confined, they must be given the
space appropriate to their physiological
and ethological needs in accordance with
established experience and scientific
knowledge.
|
59 The maximum stocking density for
chickens kept to produce meat for the table should be 34
kg/m
2, which should not be exceeded at any time
during the growing period. This stocking density is
satisfactory for chickens reared to the usual slaughter
weights (1.8 - 3.0 kg) but it should be reduced for birds
being reared to significantly lower slaughter weights.
60 However, a variety of factors need to
be taken into account when setting and monitoring stocking
densities in chicken houses at levels which promote good
welfare. The observance of any particular stocking density
is important but cannot, by itself, ensure the welfare of
the birds. There is a close relationship between
stockmanship, environmental control and stocking density.
Birds will be maintained in good condition only if the
balance is right and the onus is on the producer to
demonstrate that welfare is not compromised whatever the
stocking density.
61 Irrespective of the type of system, all
chickens should have sufficient freedom of movement to be
able, without difficulty, to stand normally, turn around
and stretch their wings. They should also have sufficient
space to be able to sit without interference from other
birds.
62 Stocking density should be reduced and
specialist advice taken if problems occur, in particular
excessive heat or humidity due to inadequate ventilation
and poor litter quality. If disease, or environmental
problems, arise in a particular building or system,
reducing the stocking density in subsequent flocks may
lessen the likelihood of recurrence.
63 A notice indicating the internal floor
area available to the birds should be clearly and
permanently displayed at the entrance of each house. This,
along with other recorded information (
see record keeping, paragraph
73), will facilitate calculation of the stocking
density.
64 Deliberately placing a high number of
chicks and routinely "thinning" should be avoided as this
causes unnecessary distress to the birds and may result in
stocking densities that are too high.
automatic or mechanical
equipment
Schedule 1, paragraph 18 of the Welfare of
Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states
that: - All automated or mechanical equipment
essential for the health and well-being of
the animals must be inspected at least once
a day to check that there is no defect in
it.
Schedule 1, paragraph 19 states that: - Where any defect in automated or
mechanical equipment of the type specified
in paragraph 18 is discovered, it must be
rectified immediately, or if that is
impossible, appropriate steps must be taken
to safeguard the health and well-being of
the animals pending the rectification of
such defects including the use of
alternative methods of feeding and watering
and methods of providing and maintaining a
satisfactory environment.
Schedule 1, paragraph 20 states that: - Where the health and well-being of
animals is dependent on an artificial
ventilation system
(a) provision must be made for an
appropriate back-up system to guarantee
sufficient air renewal to preserve the health
and well-being of the animals in the event of
failure of the system; and (b) an alarm system must be provided to give
warning of any failure of the system, (which
alarm will operate even if the principal
electricity supply to it has failed). Schedule 1, paragraph 21 states that: - The back-up system referred to in
paragraph 20(a) must be thoroughly
inspected and the alarm system referred to
in paragraph 20(b) tested, in each case not
less than once every seven days in order to
check that there is no defect in it, and,
if any defect is found in such system or
alarm (whether or not on it being inspected
or tested in accordance with this
paragraph) it must be rectified
forthwith.
|
65 All equipment and services, including
feed hoppers, feed chain and delivery systems, drinkers,
ventilating fans, heating and lighting units, fire
extinguishers and alarm systems, should be cleaned and
inspected regularly and kept in good working order.
66 Ventilation, heating, lighting,
feeding, watering and all other equipment or electrical
installation should be designed, sited and installed so as
to avoid risk of injuring the birds.
67 All equipment should be constructed and
maintained in such a way as to avoid subjecting the birds
to excessive noise.
68 All automated equipment, upon which the
birds' welfare is dependent, must incorporate a
fail-safe device and/or standby device and an alarm system
to warn the flock-keeper of failure. Defects should be
rectified immediately or other measures taken to safeguard
the health and welfare of the birds. Alternative ways of
feeding and of maintaining a satisfactory environment
should therefore be ready for use.
additional requirements for
free range birds
Schedule 1, paragraph 17 of the Welfare of
Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states
that: - Animals not kept in buildings must,
where necessary and possible, be given
protection from adverse weather conditions,
predators and risks to their health and, at
all times, have access to a well drained
lying area.
|
You should also refer to
EU Marketing Standards for
Poultrymeat, Commission Regulation (
EEC) No. 1538/91 (as
amended), regarding stocking densities, feed
requirements, access to the range and minimum
age at slaughter. |
69 Land on which range birds are kept for
prolonged periods may become 'fowl sick',
i.e. contaminated with organisms which cause
or carry disease to an extent which could seriously
prejudice the health of the birds on the land. Land should
be frequently monitored for worm burden. The time taken for
land to become fowl sick depends on the type of land and
stocking density. Appropriate measures should be taken to
prevent fowl sickness or to provide a new ranging area by
moving the housing (in the case of portable units) or to
rotating the ranging area outside fixed buildings.
70 Sufficient housing should be available
to the birds at all times and it may be necessary to
exclude birds from the range in bad weather if there is a
clear danger that their welfare will be compromised.
71 Birds should be encouraged to use the
outdoor area by provision of adequate suitable, properly
managed vegetation, a fresh supply of water and overhead
cover, all sufficiently far from the house to encourage the
birds to range.
72 Factors such as soil type, drainage and
size of colony and frequency of flock rotation are very
important in deciding the number of birds that a particular
area can carry. Heavy, poorly drained soil can carry fewer
birds than land which is light and well drained.
record keeping
Schedule 1, paragraph 7 of the Welfare of
Farmed Animals (Scotland) Regulations 2000
(S.S.I. 2000 No. 442), as amended, states that
a record must be maintained of: - Any medicinal treatment given to
animals; and
- The number of mortalities found on each
inspection of animals.
Schedule 1, paragraph 8 states that the
record referred to in paragraph 7 must be
retained for a period of at least three years
from the date on which the medicinal treatment
was given, or the date of the inspection, as
the case may be, and must be made available to
an authorised person when carrying out an
inspection or when otherwise requested by such
person. |
73 Records are an essential aid to
management and those kept should include:
- The number and sex of chicks placed.
- Daily mortality and the number and average weight
of birds removed for slaughter or when thinning the
flock to reduce stocking density.
- Number of culls with reason for cull to be recorded
(leg culls to be specifically identified).
- Where possible, feed consumed (daily and
cumulative).
- Body weight in relation to expected growth
rates.
- The internal floor area of the house.
- Daily water consumption (water meters should be
fitted in each house).
- Testing and maintenance of automatic equipment,
including alarms, fail safes, fire extinguishers and
stand-by generators.
- Daily maximum and minimum temperature.
- The lighting regime - intensity and duration.
- Dates of cleaning/disinfection and bacterial counts
between placements.
- Veterinary consultation, date and outcome.
- Medicine and vaccine administration records.
74 Additionally, for the purposes of
salmonella control, the breeding sector must keep certain
records under the Poultry Breeding Flocks and Hatcheries
Order 1993. Full details of the records to be kept can be
found in the
DEFRA booklet - "A Guide to the Poultry
Breeding Flocks and Hatcheries Order 1993". These records
will compliment those detailed above and aid flock
management.
catching, handling and
transport
The Welfare of Animals (Transport) Order
1997 (S.I. 1997 No 1480) covers the transport
of all vertebrate animals, including birds.
Among other requirements; - Article 4 states that no person shall
transport any animal in a way which causes
or is likely to cause injury or unnecessary
suffering to that animal.
- Article 6 states that no person shall
transport any animal unless:
(a) it is fit for its intended journey,
and (b) suitable provision has been made for its
care during the journey and on arrival at the
place of destination. For these purposes an animal shall not be
considered fit for its intended journey if it
is ill, injured, infirm or fatigued, unless it
is only slightly ill, infirm or fatigued and
the intended journey is not likely to cause it
unnecessary suffering. |
- For these purposes an animal shall not
be considered fit for its intended journey
if it is ill, injured, infirm or fatigued,
unless it is only slightly ill, infirm or
fatigued and the intended journey is not
likely to cause it unnecessary
suffering.Article 10(1) requires that any
person transporting animals shall ensure
that the animals are transported without
delay to their place of destination.
- Article 10(2) requires that in the case
of animals transported in a receptacle, any
person in charge of the animals shall
ensure that they are not caused injury or
unnecessary suffering while they are in the
receptacle either waiting to be loaded on
to the means of transport or after they
have been unloaded.
- Schedule 3 (Part I) requires that means
of transport and receptacles shall be
constructed, maintained, operated and
positioned to provide adequate ventilation
and air space. Receptacles in which animals
are transported shall be constructed and
maintained so that they allow for
appropriate inspection and care of the
animals. Receptacles in which animals are
carried shall be of such a size as to
protect the animals from injury or
unnecessary suffering during transport.
Receptacles in which birds are transported
shall be constructed and maintained so that
they prevent any protrusion of the heads,
legs or wings from them.
|
75 The catching and handling of birds
without causing them injury or stress requires skill. It
should only be undertaken by competent persons,
i.e. those who have been appropriately trained
to the task. Responsibility for the management of the
operation should be clearly allocated.
76 High standards must be applied
irrespective of the potential economic value of the birds.
Surplus birds or birds at the end of lay awaiting disposal
should be treated as humanely as those intended for
retention or sale.
77 Panic among the birds and subsequent
injury should be avoided. Catching should take place in low
or blue light to minimise fear responses. Catching and
handling should be carried out quietly and confidently
exercising care to avoid unnecessary struggling which could
bruise or otherwise injure the birds.
78 Unless they are caught and carried
around the body (using both hands to hold the wings against
the body), birds should be caught and carried by the legs.
No catcher should carry by the legs more than three
chickens (or two adult breeding birds) in each hand. Birds
must not be carried by the wings or by the neck.
79 One possible way of avoiding the
potential for damage to the birds is to collect the birds
mechanically; only devices proven to be humane should be
considered for use in gathering birds.
80 The distance birds have to be carried
should be minimised by taking the crates and containers
into the house. Density in the crates should be adjusted
according to weather conditions and size of bird. It is
important to ensure that once birds are loaded in the
container they are not exposed to extremes of
temperature.
81 Crates or containers should be suitable
for the purpose of transporting birds and allow them to be
put in, conveyed and taken out without injury. They should
in particular be protected from rain and road spray, which
greatly increases the effect of wind chill, although
effective ventilation must be maintained.
82 Journeys should be carefully planned so
that birds are not left on the vehicle for long periods
either at the start of the journey or at their destination.
The provision of adequate ventilation and protection from
adverse weather and extremes of temperature are essential
during loading and transport.
83 Measures should be taken to ensure
efficient removal of excess heat and water vapour. It is
important to make use of the natural airflow patterns
around a moving vehicle to optimise conditions for the
birds during transport. However, when a vehicle is
stationary for any length of time, mechanical ventilation
may be necessary to maintain acceptable levels of
temperature and humidity. When this is the case it is more
effective to extract air from the vehicle than to blow air
into it.
Schedule 3 (Part II) of the Welfare of
Animals (Slaughter or Killing) Regulations 1995
(S.I. 1995 No. 731) as amended by the Welfare
of Animals (Slaughter or Killing) (Amendment)
Regulations 1999 (S.I. 1999 No. 400) and the
Welfare of Animals (Slaughter or Killing)
Amendment (Scotland) Regulations 2001 (S.S.I.
2001 No. 145) requires that animals (including
birds) are unloaded as soon as possible after
arrival at a slaughterhouse. After unloading,
animals must be protected from adverse weather
conditions and be provided with adequate
ventilation. In addition, if any animal has
been subjected to high temperatures in humid
weather, it must be cooled by appropriate
means. |
additional recommendations for
breeding chickens
breeding procedures
Schedule 1, paragraph 28 of the Welfare of
Farmed Animals (Scotland) Regulations 2000 (S.S.I. 2000 No. 442), as amended,
requires that: - (1) Subject to paragraph (2) below,
natural or artificial breeding or breeding
procedures which cause, or are likely to
cause, suffering or injury to any of the
animals concerned must not be
practised.
- (2) Paragraph (1) must not preclude the
use of natural or artificial breeding
procedures that are likely to cause minimal
or momentary suffering or injury or that
might necessitate interventions which would
not cause lasting injury.
Schedule 1, paragraph 29 states that: - No animals can be kept for farming
purposes unless it can reasonably be
expected, on the basis of their genotype or
phenotype, that they can be kept without
detrimental effect on their health or
welfare.
|
feed and water
84 Breeding birds have been selected over
several generations for their genetic potential for large
appetites, fast growth and high fertility. Consequently,
their husbandry requirements demand committed and competent
stockmanship and a high standard of housing and equipment.
Control of the environment is essential.
85 As in many aspects of husbandry, to
promote optimum welfare the amount of feed offered to
breeding chickens is a fine balance between offering too
much feed (because birds fed to demand would become obese,
fail to survive through the laying period and breeding
would be severely impaired) and causing suffering due to
hunger and starvation. The weight of present evidence is
that the overall welfare of the bird is better if feed is
restricted. However it is particularly important that the
effects on the individual bird are carefully monitored by
skilled staff.
86 Feeding equipment
should be capable of delivering small quantities rapidly,
accurately and evenly to all birds in the house and the
amount of trough space allocated should allow access to
feed for all birds intended to be fed.
87 In no circumstances should breeding
birds be induced to moult by withholding feed and water.
Withholding feed and/or water is unlawful (
see box following paragraph
10). Paragraphs 11, 14, and 18 of this code apply at
all times, including when moulting is induced.
88 Birds should not be fed on the day of
transportation as they travel more comfortably with an
empty crop. Increased feed should be given to breeding
birds on the day before travel and water should be made
available up to the time of catching.
89 For breeding birds, it may be necessary
to manage the supply of water in relation to the feeding
system and programme to reduce excessive drinking and to
maintain litter quality. When access to water is time
limited it is vital that there is generous provision of
drinkers with adequate flow to enable all birds to drink,
without undue competition, when the water supply is turned
back on.
parent breeding chickens
90 During the first 6 weeks of life feed
levels should be adequate to ensure good skeletal
development. The level of feed intake throughout rearing
should be managed to achieve a steady growth, not less than
7% week-on-week, and the desired weight and condition at
point-of-lay.
91 Feed should be offered to the birds at
least daily throughout the production cycle with the
exception of the day before depopulation, when a more
generous allocation should be fed in anticipation of
fasting the birds before slaughter. Skip a day regimes are
not acceptable (they are also unlawful,
see box following paragraph
10).
92 In addition to routine daily checks,
the body weight and condition of the birds should be
systematically monitored and recorded on a weekly basis.
Prompt, appropriate adjustments should be made to feed
allocation according to what is found.
93 As the amount of feed offered to the
birds is so small its nutritional quality must be carefully
monitored and controlled. The flock-keeper must be
particularly vigilant after changes in feed batches.
94 During lay, cockerels and hens have
different nutritional requirements and should be fed
differently within the same house. The equipment used to
prevent cockerels taking feed intended for hens should be
carefully adjusted to ensure that access for hens is
maintained and cockerels are not injured. However, some
systems and stages in the flock require both males and
females to be fed similar amounts of feed together and so
it may be desirable to remove cockerel excluders from
female feeding systems.
elite (pedigree) birds
95 Primary breeding companies should
identify the best means of minimising the number of elite
birds subject to detailed selection performance testing and
the age and weight to which they grow on an ad libitum feed
regimen. Once the selection procedures are complete, weekly
recording of weight gain should be used to check that the
birds follow the correct body weight profile to ensure good
health and production.
96 Because of the constraints to which
they are subjected, the management of elite birds during
the period of feed restriction (from 8 weeks to
point-of-lay) must avoid any other welfare challenge and
provide even feed distribution, effective environmental
control and avoid disease challenge.
buildings and accommodation
97 Breeding birds should be reared in
houses in which temperature, humidity, ventilation rates,
light levels and photoperiods are carefully regulated. A
well designed house will incorporate insulation and
heaters, ventilation fans and vents, effective
lightproofing, and a lighting system providing controllable
light levels with uniform distribution.
98 To enrich the environment, it is good
practice to offer insoluble grit (spread on the litter)
from about 6 weeks of age. This will also help the gizzard
to break down any litter or feathers which may have been
consumed and encourage scratching. Foraging behaviour has
the added advantage of improving litter quality. Suitable
perches in the rearing house may provide a form of
enrichment to aid the birds in performing another of their
natural behaviours. Perches will also aid the
birds' adaptation from litter to raised,
perforated floors when they move to the laying house.
99 Recommended minimum light intensities
and photoperiods for breeding birds are:
- up to 10 days - minimum of 60 lux at day old,
reducing to 10 lux and an uninterrupted day length
minimum of 8 hours by 10 days of age.
- up to point of lay - minimum of 10 lux.
Uninterrupted day length minimum of 8 hours.
- laying - minimum of 20 lux. Uninterrupted day
length increasing from 8 hours to a maximum of 18
hours.
All the above should be measured at bird eye height. If
aggression occurs, the lights should be dimmed for a few
days.
After the first few days of life, there should be a set
period of at least 6 continuous hours of darkness in any
one 24-hour period.
stocking density, freedom of movement
100 Stocking density for breeding birds
should not exceed 25 kg/m
2 calculated by dividing the total weight of all
the birds (males and females) in the house by total area
available to the birds. The calculation of stocking density
should be on the basis of all stock within the house,
including males.
catching, handling and transport
101 When breeding birds are unloaded, care
should be taken when lifting the birds out of a crate or
when tipping them out of an open-topped container. Breeding
birds should have immediate access to water on arrival,
especially where slats are fitted.
disposal of surplus chicks and
embryos in hatchery waste
The permitted methods of killing surplus
chicks and embryos in hatchery waste are set
down in Schedule 11 of the Welfare of Animals
(Slaughter or Killing) Regulations 1995 (S.I.
1995 No. 731) as amended by the Welfare of
Animals (Slaughter or Killing) (Amendment)
Regulations 1999 (S.I. 1999 No. 400), the
Welfare of Animals (Slaughter or Killing)
Amendment (Scotland) Regulations 2001
(S.S.I. 2001 No.145) and any subsequent
amendments. They are: For chicks: - mechanical apparatus producing
immediate death (instantaneous mechanical
destruction);
- exposure to gas mixtures (high
concentration of carbon dioxide or argon or
specified argon/carbon dioxide mixture
containing not more than 30% carbon dioxide
and not less than 60% argon); or
- dislocation of the neck.
For embryos in hatchery waste: - mechanical apparatus producing
immediate death (instantaneous mechanical
destruction).
Chicks should always be killed by a skilled
operator. Birds must be placed in the highest
obtainable concentration of carbon dioxide,
supplied by a source of 100% carbon dioxide.
When chicks are exposed to gas mixtures, they
must remain in the gas mixture until dead. The
capacity of any mechanical apparatus must be
sufficient to ensure that chicks and embryos
are killed immediately. |
102 When using carbon dioxide or gas
mixtures, the operator should check thoroughly to ensure
that all birds are dead. When using any of the permitted
gas mixtures it is essential that the levels of each gas
are monitored and maintained as any build up in the oxygen
content will significantly reduce the effectiveness of the
system and is likely to result in birds taking longer to
die or possibly regaining consciousness. The rate of
delivery of birds should be such as to ensure that birds
are not crushed or suffocated during exposure to gas
mixtures or when passing through a mechanical
apparatus.
