1 Animal Welfare in Small Poultry Flocks Anne Fanatico, Ph.D. USDA Agricultural Research Service, Poultry Production and Product Safety Research Unit, Fayetteville, AR

2 Small-scale poultry production Small producers provide outdoor access, natural feed, no routine medications Sell to directly to consumers

3 Animal Welfare Biological Functioning Bird is healthy, growing, reproducing well Affective State Pain, fear, frustration, content Natural Living Bird should express behaviors of species Fraser, 2008

4 Industry welfare standards United Egg Producers National Chicken Council National Turkey Federation Endorsed by Food Marketing Institute and by National Council of Chain Restaurants

5 Independent Welfare Assurance Organizations Certified Humane American Humane Certified Animal Welfare Approved

6 Comprehensive programs cover Production Management Processing Record-keeping; audit Annual on-site inspection

7 Most small-scale scale poultry producers do not participate in welfare assurance programs Producer is solely responsible for welfare of flock

8 Housing Must protect birds from elements (rain, direct sun, cold, wind, heat)

9 In open-sided housing/shelters, birds often do not remain dry or may be exposed to wind Panting indicates heat stress; huddling indicates cold

10 Outdoor Area Birds should be able to express natural behaviors like foraging, running, flying, dustbathing Bird behavior is limited when confined to a pen

11 Birds should be protected from predators Use predator-proof proof housing, electric net fences; Birds of prey: use net, distraction, dog Avoid muddy or overworn areas Provide shade/shelter on pasture

12 Stock High-yielding birds Efficient meat producers, but possible welfare issues Lameness, metabolic problems AWA limits the use of fast-growing birds Only permits slow- growing

14 Health Prevent the introduction of disease with vaccinations as needed and good biosecurity/sanitation practices

15 If there is no vet, use state diagnostic lab resources Risk of poor welfare is high if treatment is needed but not obtained

16 Beak-trimming not practiced by small flock producers Must ensure no feather-pecking or cannibalism

17 Feeding Birds need a balanced diet that meets their nutritional requirements Good pasture/range helps Provide fresh water Birds drink less if water is too hot or too cold

18 Management Inspect daily Birds should not show signs of illness, injury, thinness, lameness, parasitism, soiled or damaged feathers, fractured bones, ulcerations on foot pads Birds that cannot recover should be humanely euthanized Cervical dislocation or rapid decapitation

19 Catching and transport Limit feed withdrawal to no more than 8 hours (AWA, 2008) Hold birds individually and upright; or by both legs During transport, protect birds from heat or cold Limit transport to no more than 4 hours (AWA, 2008)

20 Slaughter Avoid live shackling if possible; use cone or other restraint Bird should feel no pain at slaughter Stun before cutting neck Effective stun should result in instant loss of consciousness or not cause distress Poultry stun not required by law

21 Small-scale Stun Methods Electrical Stun knife (whole body stun) Head-only stun Captive bolt Gas Penetrating or concussive Carbon dioxide has euthanizing effect but aversive over 30%; use in combination with oxygen or inert gas or biphasic

22 75% argon and 25% CO2

23 Research is needed on captive bolt, head-only stun, and gas stun Carcass damage may result from wing flapping and convulsions

Kuenzel, and C.M. Owens, unpublished data

25 Birds should be dead before entering scalder After stunning, cut all vessels in neck Bleed for at least 2 minutes

26 Conclusions Many inherent welfare advantages to small flocks Outdoor access, generous space, natural molting, little transportation and handling However, some practices can be hard to justify from welfare point of view Inadequate housing, confinement on pasture, no stunning Welfare of farm animals is not protected by law as much as other animals Producer has sole responsibility for bird well-being
