摘要
通过玉米秸秆青贮草中添加和不添加碳酸氢钠(1%)饲喂小尾寒羊进行试验对比,经45d的育肥,观察了羔羊育肥的生产性能和健康状况。结果表明:添加碳酸氢钠的试验组较对照组的日采食量、只均日增重均有很大提高,差异极显著(P<0.01);只均增重较对照组提高52.03%;试验组羔羊的腹泻、流涎、脱毛食毛症总发病率较对照组有了大幅度的下降。青贮玉米秸中添加碳酸氢钠饲喂羔羊,可提高羔羊的生产性能,明显改善健康状况,经济效益显著。
Production performance and health condition of Small Tail Han sheep were observed after 45 days fattening by adding sodium bicarbonate supplementation on the cornstalk silage. The results indicated that average daily feed intake and av- erage daily gain in the group supplemented with sodium bicarbonate were significantly higher than the group without sodium bi- carbonate （P〈0.01）. Moreover, overall incidence of diarrhea, hydrostomia and fleece-eating in the treatment group were re- duced compared to the control group. In conclusion, silage cornstalk supplemented with sodium bicarbonate could improve the productive performance and health status. In addition, it could increase economic efficiency of Small Tail Han sheep.
