L-Arginine
CAS Number: 74-79-3
L-Arginine is a semi-essential amino acid critical for nitric oxide synthesis, immune function, and reproductive performance in poultry and swine. It is particularly important in broiler diets where the arginine-to-lysine ratio directly affects growth and cardiovascular health. Our feed-grade L-Arginine is produced by fermentation to deliver reliable purity for nutritional applications.
