湖寒杂交羔羊与湖羊羔羊补饲效果研究

Comparison on the supplementary feeding effect between hybrid of Small-Tail Han sheep × Hu sheep and Hu sheep

试验旨在分析湖寒杂交与湖羊2个品种羔羊应用不同饲料补饲的增重效果、饲料报酬以及经济效益。采用完全随机单位组设计方法,选择体重、年龄相近的2周龄羔羊76只(湖羊38只、湖寒杂交38只),随机将2个品种羔羊各分为2组,即试验Ⅰ组(湖羊,自配料组)、试验Ⅱ组(湖羊,商品料组)、试验Ⅲ组(湖寒杂交,自配料组)、试验Ⅳ组(湖寒杂交,商品料组),进行饲喂试验。结果表明:使用自配料能达到降低饲养成本、增加养殖经济效益的目的 ;无论饲喂自配料还是饲喂商品羔羊料,湖寒杂交羊的增重速度都高于湖羊羔羊,湖寒杂交羔羊每增重1 kg的饲料成本都低于湖羊羔羊。

The aim was to analyze the weight gain, feed remuneration and economic benefits with commercial formula feed and the mixed feed in two varieties lamb. The feeding experiment is based on complete random test. Choose 76 sheep (Hu sheep 38,Hu x Small Tail Han crossbred sheep 38) with the similar weight, aged 2 weeks and randomly divide them into two groups respectively. The test group I (Hu sheep, Self-made group), the test group II (Hu sheep, commodity group), test DI group (Hu x Small Tail Han crossbred, Self-made group) and test IV group (Hu x Small Tail Han crossbred, commodity group). The trial showed that the ingredients can reduce feeding cost and increase the economic benefit. By being fed the ingredients or commercial feed, Hu x Small Tail Han crossbred lamb's weight gain rate was higher than that of Hu lamb, the cost for Hu x Small Tail Han crossbred lamb per kg weight of sheep was lower than that of Hu lamb.
