Poultry Judging Practice Test

Which gas is typically released in poultry houses when litter is not changed regularly?

1. Carbon dioxide

2. Methane

3. Ammonia

4. Nitrogen

The correct answer is: Ammonia

When litter in poultry houses is not changed regularly, ammonia is the gas that is typically released. Ammonia originates from the breakdown of nitrogenous compounds found in manure and litter. The decomposition process, facilitated by moisture and microbial activity, converts waste materials into ammonia gas. High levels of ammonia can pose health risks to both the birds and poultry workers, leading to respiratory issues and other health problems. Additionally, elevated ammonia levels can negatively impact the overall environment inside the poultry house, affecting bird comfort, growth rates, and feed efficiency. Therefore, regular litter management is crucial not only for biosecurity but also for maintaining a healthy living environment for the poultry.
