摘要
用6头西门塔尔牛与本地黄牛的二元杂交后代公牛,对玉米、皇草青贮料在补充不同饲料的基础上进行了消化率、日增重及经济效益的比较研究。结果表明:青贮皇草与青贮玉米比较,可消化粗蛋白及可消化干物质和可消化有机物采食量均较低,因此其饲养效果亦较差;当用青贮玉米、皇草饲养肉牛时,适当添加一定量的混合精料和干草,有利于提高牛的粗蛋白和可消化干物质及有机物的采食量,从而提高其饲养效果。
Six crossbred bulls(Simmental × Local yellow cattle) were randomly allotted to 2 groups fed with corn silage and King grass silage, and digestion rate, daily gain and economic profit were measured, respectively. The results showed that the digestion rate of crude protein, dry matter and organic matter of King grass were all lower than those of corn silage, and when some mixed concentrate and dry grass were supplemented to the diet of corn silage and King grass, feed intake and the digestion rate of crude protein and organic matter couldbe improved, finally better economic profit could be realized.;
