泌乳反刍动物乳腺的氨基酸代谢

Amino Acid Metabolism in the Mammary Gland of the Lactating Ruminants

乳腺是合成乳汁的主要场所。为了提高反刍动物饲料转化效率、泌乳量和乳蛋白产量,就有必要把乳腺氨基酸代谢作为研究的基础。本文从氨基酸供应、乳腺对氨基酸的摄取、乳腺氨基酸的代谢、能量供应对乳蛋白合成的调节等4方面,对泌乳反刍动物乳腺的氨基酸代谢进行综述,为进一步深入研究乳腺代谢,调控乳产量、乳蛋白含量提供依据。

Mammary gland is the main site to synthesize milk. To improve the conversion efficiency of dietary nutrients (energy and protein) into milk and increase the yield of milk and protein content, it is necessary to clarify amino acid metabolism in the mammary gland. In this article, the authors have reviewed the supply of amino acid, uptake of amino acid by mammary gland, metabolism of amino acid by udder, and effect of energy on milk protein synthesis, thus providing a basis for further study and maniputation of output of milk.
