饲喂代乳品对羔羊早期断奶技术的研究

为缩短羊的繁殖周期，解决因母羊产奶不足而影响羔羊生长发育的问题。探索人工代乳品对羔羊早期生长发育的作用，加强羔羊早期生长发育营养水平和饲养管理，以达到羔羊早期断奶，降低培育成本，进行了对羔羊早期断奶饲喂代乳品断奶试验。试验组羔羊自35日龄进行代乳品过渡，40日龄完全断奶。对照组羔羊随母羊自由哺乳。结果表明，早期断奶不仅提高了羔羊的日增重，而且大大降低了羔羊的死亡率，提高了养羊的经济效益，同时使用羔羊的代乳品有利于加快母羊的繁殖率，缩短世代间隔。

Study of Substitute Milk on Technique of Lamb Ablactation at Nonage

The purpose of this article is:(1)in order to increase nutrition level of lamb growth at nonage,(2)to research the role of the substitute Milk play on lamp growth at nonage,(3)decrease culture invest shorten hogg's reproduction cycle largly,(4)resolve the problems of effecting lamb growth caused by inadequate ewe-milk.The results indicated that technique of using substitute mile at 35 d and ablactating at 40 d was useful to quicken reproducing efficiency,shorten generational space.Moreover,ablactation at nonage was not only increasing weight increment per day,but also decreasing deeply mortality rate,enhancing economical efficiency.
