Lysine is one of the essential amino acids for animals and plays a central role in feed nutrition. Its core function is to act as the first limiting amino acid, participating in protein synthesis and directly determining the growth rate, feed utilisation efficiency, and overall productive performance of animals, especially pigs and poultry.

Specifically, its main effects include:

• Promoting growth and tissue repair: It is a fundamental building block for synthesising body proteins, muscle, enzymes, and hormones.

• Improving feed efficiency: By balancing the amino acid profile, it enables more effective utilisation of other amino acids in the diet, thereby reducing feed costs.

• Enhancing carcass quality: It helps increase lean meat percentage and reduce backfat thickness.

• Boosting immune function: It is essential for the synthesis of antibodies and immune factors.

• Influencing reproductive performance: It has a significant impact on the fertility of breeding stock and poultry.
