摘　　要：精氨酸是幼龄哺乳动物和鸟类等的必需氨基酸,成年哺乳动物的条件性必需氨基酸,饲粮中精氨酸含量过高或不足均显著抑制动物摄食。研究表明,精氨酸可在一氧化氮合酶作用下生成一氧化氮(NO),NO通过作为动物主要增食和厌食生理调节因子的下游信号分子参与动物的摄食调控。精氨酸可在精氨酸脱羧酶作用下生成胍丁胺,胍丁胺通过与肾上腺素能受体作用刺激动物摄食。本文主要对精氨酸代谢、精氨酸对动物摄食的影响、精氨酸代谢产物与主要摄食生理调节因子的关系进行了综述。Arginine is an essential amino acid for birds and young mammalian animals, and conditioned-essen- tial amino acid for adult mammals. Arginine deficiency or overdoes in a diet would significantly decreased in- gesting behavior. Research showed that arginine could be converted to nitric oxide by nitric oxide synthase （NOS） in an animal body, and the latter has been discovered to regulate feed intake as downstream signal mo- lecular of anorexic and orexigenic hormones. In addition, agmatine, produced from arginine decarboxylation, can stimulate feeding behavior via activating adrenergic receptors. The metabolism of arginine, the effect of arginine on animal ingesting, and the interaction of arginine and the main ingesting regulatory factors were re- viewed in this paper.
