Contributors: Y. Li n, H. Wei*, F. Li*, S. Kim n, C. Wen*, Y. Duan*, Q. Guo*, W. Wang*, H. Liu*, Y. Yin*

author keywords: amino acid transceptor; free amino acids; growing pig; low-protein diet; mammalian target of rapamycin complex 1 pathway; skeletal muscle
MeSH headings : Amino Acids / analysis; Amino Acids / metabolism; Animal Feed; Animal Nutritional Physiological Phenomena / drug effects; Animals; Biosynthetic Pathways / drug effects; Blood Urea Nitrogen; Diet / veterinary; Diet, Protein-Restricted / veterinary; Dietary Supplements; Female; Muscle, Skeletal / metabolism; Swine / physiology
topics (OpenAlex): Muscle metabolism and nutrition; Adipose Tissue and Metabolism; Biochemical effects in animals
TL;DR: The results indicate that supplementing with limiting AA to the 14%CP diet is not highly effective for the pigs in restoring protein synthesis and muscle growth, whereas the 17% CP diet likely maintains the pigs' muscle mass, which were regulated by mediating AA transceptors expression, FAA profile, and activation of the mTORC1 pathway.
