USDA APHIS Poultry Vaccination & Flock Health

The USDA Animal and Plant Health Inspection Service publishes guidance on poultry disease prevention, including Newcastle disease, infectious bronchitis, and avian influenza risk mitigation. While tailored to the United States, the principles of hatchery vaccination, uniform administration, and serological monitoring are widely adopted.

Pakistani integrators can adapt these frameworks alongside WOAH and national disease profiles when designing layer and broiler programmes.
