Poultry FCI & AM inspection Flashcards
How can bird welfare be assessed
What are the legal responsibilities (legislations) of vets for animal welfare
What committees/associations are involved in poultry welfare
Describe the AWC report May 2009 for poultry
Describe the DEFRA code of recommendations for poultry
Describe the HSA 2006 guidance for poultry
Visibly unfit or injured birds should not be loaded into a transport module but should be killed on farm as quickly and humanely as possible by a suitably trained person.
Describe depopulation/harvesting of poultry
Commercial birds have lived relatively ‘controlled’ lives:
- Met relatively few people;
- Noise is typically constant and predictable;
- Possibly in subdued light.
Catching represents a major departure from their normal daily ‘structure’.
Large numbers of individuals (low individual value)
Genetic selection - inherent problems:
- Broilers – leg problems
- Laying hens - osteoporosis
Catching identified as major source of stress & injury
Possible injuries: bruising, fractures, dislocation
What are the advantages and disadvantages of mechanised harvesting in poultry
Describe depopulation/harvesting of spent hens
Describe the transport of poultry
Describe the welfare issues of poultry transport
Describe thinning system vs all in all out system poultry
38kg per m2 is max stocking density
thinning system: better welfare, uses lower stocking density (30kg per m2)
- maximises efficiency/use of house
- temporary social disruption
all in all out: reach 38kg per m2 at end of cycle and all birds cleared out
Describe broiler transport with regards to temperature
Broilers particularly susceptible to heat stress and dehydration
Genetic selection for muscle growth has compromised capacity to respond to acute thermal challenge:
- Reduced tolerance has implications for welfare and meat quality
Heterogeneous distribution of ventilation in passively ventilated transporters – ‘hot-spots’ and ‘cold-spots’;
Different birds in same load may experience heat or cold stress - localised high air velocities;
High stocking density, minimal head room and high humidity compromise ability to thermoregulate by natural means - panting, postural changes.
Describe thermal comfort zone for broilers
Describe transport of chicks with regards to temperature
