Conventional diets containing corn and soybean meal fed to growing pigs can be reduced in protein when a portion of the protein can be replaced by crystalline amino acids. These amino acids allow the animal to digest dietary proteins more efficiently, with decreasing nitrogen excretion and ammonia emission into the air. However, the level of inclusion of these amino acids is limited because the rate of absorption by the gut is increased relative to the other amino acids found in intact feeds. Strategies to decrease the rate of absorption of crystalline amino acids may be an approach to allow more inclusion of crystalline amino acids in growing pig diets, thus minimizing environmental pollution.
