Research Abstract |
It was found that valine and methionine stimulated protein synthesis when chicken embryo myoblasts were incubated in single amino acid deficient medium. Valine stimulated protein synthesis with elevation of gene expression of insulin-like growth factor type-1 receptor. However, dietary valine supplementation did not improve growth performance of chickens. Supplementation of both methionine and glycine in a low-protein diet improved feed efficiency of broilers.
