Lysine
L-Lysine is one of the most widely used amino acids. It is an essential amino acid required in the diets of swine, poultry and most other animal species. L-Lysine is frequently missing in most animal feeds, and it is the neccesary amino acid for the animals which cannot be synthesized by themselves and must be supplied straightly from feed. Therefore, it is called "the first restrained amino acid".
By adding it to the animal feed enables the animals to get a more balanced diet. L-Lysine forms an essential part in animals' diet. Inclusion of L-Lysine in the feed can help enhance the protein utilisation and balance the amino acids in animals.
