摘要: 奶牛繁殖性能下降与能量和蛋白质有关,本文系统地介绍了日粮能量和蛋白质水平对奶牛繁殖性能影响的研究进展,并着重论述了能量负平衡(NEB)及日粮蛋白质、脂肪酸和氨基酸对奶牛繁殖的影响.
英文摘要: Decline in reproductive performance of dairy cows was closely related to dietary energy and protein levels. This paper systematically introduced the research progress of the effects of dietary energy and protein levels on the reproductive performance of dairy cows,focusing on negative energy balance (NEB) and dietary protein,fatty acid,and amino acid levels.
