补饲水平对安徽白山羊母羊体况和繁殖性能的影响研究

Effect on Body Condition and Reproductive Performance of Ewe by Feeding Level in Anhui White Goat

为了探讨日粮补饲量对母羊体况和繁殖性能的影响,试验选择安徽白山羊能繁母羊为试验对象进行分组饲喂,对照组补饲玉米,试验组补饲不同的混合精料量,测定母羊的繁殖性能和膘情体况等指标。结果表明,通过补饲精料后,提高了试验组能繁母羊的繁殖性能和妊娠母羊体况,提高了羔羊初生重、成活率,但对平均产羔数没有影响,补饲0.4 kg/d混合精料对提高母羊的繁殖性能和维持整个妊娠期的体况最好。

In order to explore the influence of body condition and reproductive performance in ewe by dietary supplementation, Anhui White Goat ewes were selected and randomly divided group respectively, the control group only were feed corn, the experimental groups were feed mixed concentrate respectively. The indexes of ewes about reproductive performance and body condition and other indicators were measured. The result showed that the test could improve the reproductive performance and body condition of ewes, increase the lamb birth weight and survival rate, but had no effect on average lambing number by controlling the diet supplement. It can be drawn an conclu- sion that it was best that supplementary feeding 0.4 kg/d mixed concentrate to improve the repro- ductive performance and sustain the whole body condition of ewe pregnancy.
