What is the recommended action when a flock of broilers is sick and antibiotics are ineffective?

Conducting a necropsy on deceased birds is a pivotal step when a flock of broilers is exhibiting sickness and antibiotics have proven ineffective. A necropsy, or post-mortem examination, allows veterinary professionals to determine the underlying cause of illness or death in birds. This procedure can reveal critical information about infectious diseases, parasites, nutritional deficiencies, or other health issues that may not be evident through clinical signs alone. By identifying the specific cause of death or illness, appropriate treatment protocols can be established and implemented for the remaining birds, rather than solely relying on antibiotics that have failed to address the underlying issue. This approach ultimately enhances flock health management and can prevent further losses.
