巨菌草青贮饲料饲喂肉牛的研究

为了开发巨菌草作为肉牛的饲料资源,并探索巨菌草对肉牛的增重效果,应用玉米秸秆青贮、带穗玉米青贮和巨菌草青贮对夏秦杂交牛进行饲喂试验。结果表明,与对照组（玉米秸秆青贮）相比,试验组Ⅰ（带穗玉米青贮）和试验组Ⅱ（巨菌草青贮）平均头均日增重提高率分别为35.3%、17.6%;试验组Ⅰ比试验组Ⅱ青贮效果更好。综上提示,巨菌草可以作为陕北地区冬季饲料资源推广应用。

Feeding Effect of Pennisetum sinese Silage on Beef Cattle

In order to develop Pennisetum sinese as a feed resource for beef cattle and to assess the feeding value of Pennisetum sinese on beef cattle, the feeding effect of corn stalk silage, whole ear corn silage and Pennisetum sinese silage on crossbred beef cattle of Charolais and Qinchuan cattle were evaluated and statistically compared. The results showed that the individual average daily gain of the crossbred beef cattle fed with whole ear corn silage and Pennisetum sinese silage were elevated by 35.3% and 17.6% compared to that of the beef cattle fed with corn stalk silage, respectively; whole ear corn silage was better than Pennisetum sinese silage. Collectively, Pennisetum sinese has the potential to serve as feed resource in winter in northern Shaanxi area.
