L-valine is used in the feed sector as a supplementary component in mixtures for pigs, poultry and other farm animals. Its role is to supplement the valine content of the formulation and to balance the amino acid profile of the feed against the animals’ requirements.
Valine becomes one of the limiting amino acids in low-protein diets for monogastric animals. Supplementing feed with L-valine allows the supply of branched-chain amino acids (BCAA) to be matched to requirements without over-formulating on crude protein, which is applied among others when formulating feeds with a reduced crude-protein content.
L-valine is also used in premixes and mineral-vitamin mixtures, where it serves to supplement the BCAA level in the feed composition.
