Here are five ways to reduce ammonia levels in poultry houses: Ration composition and diet management, provision of a balanced, complete diet are of the highest importance. Problems occurring due to high-performance genetics, feed formulation, and medication can lead to the production of wet manure, causing increased ammonia and odor release alongside reduced broiler performance and feed efficiency. Optimize the poultry stocking density to help limit excessive moisture in the poultry house, so reducing anaerobic processes. Adjust the ventilation rate – if ammonia levels increase, more ventilation is needed. However, this should only be in accordance with the climate and temperature of the poultry house. Temperature adjustments should be made relating to house climate and welfare. Improve nutrient digestibility. This could also be achieved by supplementing diets with additives.
