Which statement describes a sign NOT typically associated with highly pathogenic avian influenza?

• A. Neurologic Signs
• B. Increased Appetite
• C. Respiratory Signs
• D. Decreased Egg Production

Answer: (B)

High-pathogenic avian influenza in poultry typically produces a severe systemic illness that suppresses normal behavior and production. Birds often become depressed, ruffled, and choose to eat less, not more, and they show signs tied to the respiratory tract or the nervous system as the disease progresses. Increased appetite is not expected in this context.

Respiratory signs like coughing, sneezing, nasal discharge, and difficulty breathing can occur because the virus infects the respiratory tract. Decreased egg production is common in layers due to the systemic illness and stress on the reproductive system. Neurologic signs such as ataxia, tremors, or twisted neck can appear with neurotropic strains. So the statement describing increased appetite does not fit the typical disease picture.
