L-Arginine, an essential amino acid for poultry and aquatic animals and conditionally essential for swine, is necessary for animals’ growth and reproduction. In particular, poultry and aquatic animals are not able to synthesize L-arginine themselves, and therefore depend on dietary L-arginine to meet their needs for protein synthesis and other functions. It is the 4th limiting amino acid in broiler and aqua feed and the 7th limiting amino acid in swine feeds. (The order of limiting amino acids can differ depending on environment or feed ingredients.)
