L-Lysine feed grade is a highly important essential amino acid for animal nutrition. It is commonly used as a feed additive to ensure animals receive appropriate levels of this nutrient in their diet. L-Lysine is essential for proper growth, muscle development, and overall protein synthesis in animals. It is especially crucial for monogastric animals like pigs, poultry, and fish, as they cannot synthesize L-Lysine on their own and rely on dietary sources. L-Lysine feed grade helps optimize animal performance, enhance feed conversion efficiency, and support a healthy immune system. In feed formulations, L-Lysine is added to balance the amino acid profile, particularly in plant-based diets that may be deficient in this essential nutrient.
