Market Broiler Management Practice Test

What are potential negative effects of ammonia exposure on broilers?

1. Decreased appetite

2. Foot pad burns

3. Feather pecking

4. Brooding problems

The correct answer is: Foot pad burns

The choice of foot pad burns as a potential negative effect of ammonia exposure on broilers is correct because ammonia can irritate the skin and mucous membranes, including the areas on a broiler's feet. When ammonia levels are high in the poultry house, it creates an environment that can lead to chemical burns, particularly on the foot pads. This occurs because ammonia is a potent irritant, and prolonged exposure to it can damage the delicate tissues on the feet. Consequently, this can lead to lesions, increased susceptibility to infections, and pain for the birds, impacting their overall welfare and performance. Other potential negative effects like decreased appetite, feather pecking, and brooding problems are also relevant to poultry health, but they may not be as directly associated with ammonia exposure as foot pad burns are. Decreased appetite can stem from various factors, including environmental stressors, but is not specifically a direct consequence of ammonia irritation. Feather pecking can be a behavioral issue influenced by several environmental and social factors. Brooding problems can arise from multiple elements such as temperature and humidity but aren't specifically tied solely to ammonia. Thus, foot pad burns provide a clear, specific consequence of ammonia exposure, making it the most precise choice in this context.
