摘　要：摘　要：仔猪出生后早期阶段能高效地利用日粮氨基酸进行体蛋白质(尤其是骨骼肌蛋白)合成。这种高效的蛋白质沉积与摄食后血浆胰岛素及营养物质(氨基酸、葡萄糖等)水平升高有密切关系，餐后血浆胰岛素、氨基酸及葡萄糖水平的提高，能显著刺激新生仔猪蛋白质合成。本文着重就摄食引起胰岛素及营养物质信号通路的活化对新生仔猪蛋白质合成的作用效果及其作用机制作一综述。

Abstract: Abstract: The neonatal period is characterized by high growth rate and protein accretion rate, especially with the most rapid gain occurring in skeletal muscle, which is in part due to the ability of neonatal pigs to markedly increase protein synthesis in response to feeding. Postprandial could rise in insulin and nutrients such as amino acid and glucose, which modulate the protein synthesis significantly. This paper summarizes the effects and mechanisms of feeding-induced activation of early insulin-signaling pathway and nutrients-signaling pathway leading to the stimulation  on protein synthesis of neonatal pigs.
