The improvement of nutrients incorporation in pigs used as human food is an important subject for reducing the environmental impact of swine production and enhancing animal intestinal health. This review focuses on nitrogen (N), amino acids (AAs) and phosphorus (P) from swine with manipulation of the diet. Most of the data obtained from the Project of Applied Techniques of Regulating Nitrogen and Phosphorus Metabolism in Pigs and Environmental Safety and Research and Application of Biological Mechanisms and Regulation Technique in Intestinal Health of Piglets performed at our research center, focused on three main aspects: 1) the nature of N and AA metabolism, including methods for development of practical methods to measure available AAs, their degradation by digestion, and factors that affect the use of absorded AAs, 2) the nature of P digestion and absorption, 3) development of novel strategies to regulate N and P. The most exciting of these techniques include 1) formulating diet based on digestible ileal AAs and reducing dietary crude protein levels and balancing digestible AA requirements with synthetic AAs and food enzyme supplementation, 2) stage feeding, 3) ways to reduce the endogenous secretion of N, and 4) use of functional amino acids enhancing animal health.
