Abstract
This study reviews the effects of pig slurry composition on potential NH3 emissions, using the information collected in three nutrition assays. A total of 84 animals were used to test the effect of 13 different diets. These included different types and sources of fibre, different sources of protein, and different inclusion levels of fat and fibre. The result indicates that diets tested changed digestion parameters and nitrogen partition among faeces and urine, which was related to changes in NH3 emissions. Thus, modifying nitrogen sources in diet resulted in the most effective strategy to reduce NH3 emissions from slurry
