Newcastle disease is a highly contagious viral disease that affects many species of domestic poultry including chickens, ducks, geese, and turkeys. Symptoms include respiratory distress, depression, diarrhea, and neurologic signs such as tremors and paralysis of wings and legs. The mortality rate for infected birds can range from mild to high depending on the strain involved in the outbreak. Vaccination programs can help protect flocks from Newcastle disease but it’s important for poultry producers to practice good biosecurity protocols such as using clean footwear when entering poultry houses to prevent the spread of infection. Additionally, producers should be aware of any changes in behavior or physical appearance among their flocks so they can seek medical help if needed. Properly disposing of dead birds is also key in preventing outbreaks as Newcastle disease is highly contagious and can spread quickly through contaminated surfaces or even airborne particles.
