| 摘 要： | 能量是影响母羊繁殖性能的重要因素之一。满足母羊不同时期的能量需求是提高母羊生产效益的重要措施,对保证母羊繁殖和羔羊健康生长有重要意义。能量主要通过下丘脑-垂体-肾上腺轴来影响母羊的繁殖性能。文章综述不同能量水平对母羊的发情、胚胎发育、泌乳和羔羊生长的影响,以期为母羊合理的日粮能量水平提供依据。

| Abstract: | Energy is one of the important factors affecting the reproductive performance of ewes. Meeting the energy needs of ewe in different periods is an important measure to improve the efficiency of ewe production, which is of great significance to ensure ewe reproduction and lamb healthy growth. It shows that the energy mainly affects the reproductive performance of ewe through the hypothalamus-pituitary-adrenal axis. The article reviews the effect of different energy levels on ewe’s estrus, embryonic development, lactation and lamb growth, in order to provide references for reasonable dietary energy levels for ewes. |
