Poultry production vaccination challenges: What does it mean for animal welfare?

  1. 1. Poultry production vaccination challenges: What does it mean for animal welfare? • Poultry welfare is obviously increased with the prevention of disease • Malaise, pain, dehydration and emaciation, decreased productivity, immunosuppression, reduced liveability (Butterworth & Weeks, 2010) • Management conditions, social status and behaviour contribute to individual disease susceptibility • Disease outbreak control: culling humanely at scale creates significant risks to welfare & livelihoods (photo credits: ILRI) The Animal Welfare Science Centre

  3. 3. Vaccination & welfare barriers Vaccines, when implemented, can fail for a whole host of reasons • Small animals with short lifespans, so often overlooked individually • Animal health services are poorly supported • Farmers are presumed to not care, or not know enough. This misses the complexities and deficits of the systems in which they operate, the risks they take on, and impact poor outcomes on their risk-taking threshold • Programs that involve animals need to consider the animal across its whole lifetime Sasso day old chicks were hatched and brought to the brooder houses contracted by the ACGG Tanzania team.

  4. 4. Welfare & production opportunities • Vaccines as part of a broader control strategy: including improved biosecurity, hygiene, management and animal welfare [Guide to chicken health and management in Ethiopia & Controlling Newcastle disease in village chickens: a training manual] • Role of breeds: local breeds are more resilient • Good stock management for early identification and intervention when disease – or any other welfare challenges – are detected A smallholder farmer providing locally available feeds to improved Kuroiler and Sasso birds (Photo credit: TALIRI)
  5. 5. “In the pragmatic world of farming, flock health status may be frequently chosen as the index of welfare, but it is important not to lose sight of the health and well-being of each individual, even in flocks numbering tens of thousands of birds” - Butterworth & Weeks, 2010 Rebecca Doyle International Livestock Research Institute & University of Melbourne rebecca.doyle@unimelb.edu.au A woman sells live ducklings in a 'wet market' in Indonesia (photo credit: ILRI/Chris Jost).
