柠条饲喂山羊效果试验

Goat feeding experiment for Korshinsk Peashrub(Caragana korshinskii)

在春季将没有发芽的2～3年生柠条Caragana sp．枝切成1～3cm短节。对波尔山羊、本地黑山羊及波尔山羊杂种羊进行舍饲饲喂试验，经30d的正式饲养试验。其结果为：柠条代替基础日粮中50％干玉米秸秆，羊只日增重为129g；柠条代替基础日粮中70％干玉米秸秆组，羊只日增重为122g；单纯饲喂干玉米秸秆组羊只日增重为128g；单纯饲喂柠条组羊只日增重为8．33g（黑山羊）。结果表明，柠条在冬春季可作为羊的基础饲草利用。

2～3 year＇s Korshinsk Peashrub branches were cut to 1～3 cm short lengths in spring, shed feeding to Boer goat,local black goat and Boer goat hybrid. After 30 days formal feeding experiment, the results showed： Korshinsk Peashrub substituting 50 percent maize straw of the basal diet, average daily gain of goat was 129 g; in the group of Korshinsk Peashrub substituting 70 percent maize straw, average daily gain was 122 g; the group of pure feeding dry maize straw had average daily gain 128 g; and the group of pure feeding Korshinsk Peashrub had average daily gain 8.33 g （black goat）. Generally, Korshinsk Peashrub can be used in the basal feed for goat in winter-spring.
