Feed-grade L-lysine is widely recognized in livestock and poultry feed as thefirst limiting amino acid,and its core value lies inprecisely balancing the amino acid profile of the feed,bringing the amino acid ratios closer to the ideal protein pattern, therebysignificantly promoting muscle protein deposition in animals, improving daily gain and lean meat percentage, and effectively reducing the feed-to-meat ratio.In addition, lysine can significantly improve the utilization of common feed ingredients such as corn-soybean meal diets, helping youoptimize nitrogen deposition efficiency while reducing the crude protein level of the feed,greatly reducing waste of protein ingredients and lowering formulation costs. Moreover, it effectively reduces nitrogen emission in manure,significantly lowering the ammonia concentration in livestock and poultry houses,improving the rearing environment; and by participating in the synthesis of enzymes and hormones in the body,it enhances the stress resistance and production performance of livestock and poultry.Choosing feed-grade lysine is choosingefficient muscle building, cost savings, and environmental friendliness—a powerful tool for animal farming.
