The swine nutrition in recent years has been the focus of several experimental studies, especially in relation to protein and amino acid nutrition. In this context, arginine is one of the amino acid in increasing research, which metabolism is dynamic, participating in several metabolic pathways and generating numerous compounds. The arginine synthesis occurs primarily in the intestinal-renal axis, where lining cells from the small intestine produce citrulline and proximal tubule cells from kidney extract citrulline from the bloodstream, converting it into arginine, returning it to circulation. Arginine is chemically named 2-Amino-5-Guanidopentanoic Acid, and it is a conditionally nonessential amino acid for pigs, considering that is required primarily... |
