Lysine

Lysine is an important additive in many animal feeds, particularly swine and poultry, but also plays an important role in aquaculture, dairy cattle and companion animal feeds.

Pigs require proteins, polypeptides and amino acids in their diets in order to grow and to build muscle tissue. The protein components of corn and other cereal grains are deficient in lysine, so that protein-rich soybean meal is used in swine feed to increase the content of available amino acids.

An ideal formulation combines soybean meal and amino acids, based on the specific life cycle requirement of the species. For typical corn/soy-based diets for pigs, lysine is said to be the “first-limiting,” or the first nutrient to limit the animal’s growth unless it is supplemented.

Similarly, for broiler chicken and laying hen diets, lysine is either the second- or third-limiting amino acid (after methionine) in corn/soy-based diets. Therefore, lysine is a critical additive for poultry diets as well.
