A Low Protein Diet and Oil Sprinkling to Reduce Ammonia Emissions from Pig Barns
Ammonia concentrations have adverse effects on the environment and the health of workers and animals. Reducing dietary protein and using fermentable carbohydrates in diets previously resulted in reduction of ammonia emissions. Oil sprinkling may also have an impact on ammonia emissions. Fermentable carbohydrates with a low protein diet reduced emissions by 42% while oil sprinkling did not have an effect on the ammonia levels.
