摘    要:本文从奶牛泌乳、采食及体重变化入手,简要论述了饲粮蛋白质和能量水平对奶牛繁殖性能的影响,探索高产奶牛繁殖力较低的原因。奶牛场追求高产奶量,多会采取高比例精料、高蛋白水平的饲粮,从而造成过量氮化物对奶牛繁殖性能的毒害。产后泌乳量的快速上升和饲料干物质采食量的不足足导致了能量负平衡、体况评分下降过大、卵泡发育迟缓、产后发情晚、配种受胎率低、产犊间隔长等一系列问题。

关 键 词:奶牛  繁殖  蛋白质  能量

Abstract:The article was conducted to explore why the high productive dairy cows had lower reproductive through study the effects of protein and energy in diets on reproductive ability base on lactation of performances, foraging and change of body mass. Dairy cow farms hunted for high production by feed the cow with high ratio of Concentrate-Diet and diet with high level of protein, resulted in excessed nitrides influenced dairy cow reproductive. Increased lactation and deficient dry matter in diet led to a series of problems including energy negative balance, decreased body condition score, follicular development retardation, delayed oestrus, lower conception rate, longer Calving Interval.
Keywords:dairy cow  reproductive ability  protein  energy
