How to Prevent Newcastle Disease on Your Farm

Newcastle disease is one of the most destructive viral infections in poultry, causing respiratory distress, green diarrhea, and nervous signs like twisted necks. It can kill 100% of an unvaccinated flock within days. The virus spreads through air, feed, water and human contact. Preventive vaccination is non-negotiable. Use live or inactivated vaccines as per schedule—usually at 7, 21, and 35 days. Biosecurity must include disinfection routines, quarantine for new birds, and limited farm access. Never bring in birds or equipment from unknown sources without testing. If an outbreak occurs, inform veterinary authorities immediately. Cull infected birds and destroy carcasses far from the farm. Disinfect all surfaces and pause new batches until clearance. Newcastle disease is preventable, but once it hits, recovery is hard. Prevention is your only safe bet.
