摘要
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.
