不同日粮组合模式对肉牛生产性能的影响

肉牛育肥中应该合理搭配精、粗饲料,并科学地对肉牛日粮中的粗料部分进行深加工,以提高其适口性和营养价值。本试验以西黄牛(西门塔尔×本地黄牛)(12～18月龄)为试验对象,分别饲喂不同组合日粮,对其肉牛生产性能、增重效果和获得的经济效益进行研究。结果表明,在增重方面,日粮中粗饲料中青贮玉米比黄贮玉米的增重效果明显(P<0.05),粗饲料中青贮玉米比氨化秸秆的肉牛育肥增重量高5.05%(P>0.05)。在经济效益方面,饲喂青贮玉米和氨化秸秆,在增重速度、饲料报酬和经济效益等方面均优于饲喂桔秆组。

Effect of Dietary Combination Pattern on Beef Cattle Growth Performance

The concentrate and roughage should be reasonable collocated and deeply processed to improve its palatability and nutritional value.Simmental crossbreds(Simmental cattle×local yellow cattle) from 12-month old to 18-month old were as object of study,different dietary were feed and growth performance,body weight gain and economic benefit were studied.The results indicated that weight gain effect of roughage with silage maize was significantly higher than yellow storage(P<0.05),and the weight gain of roughage with silage maize was increase for 5.05% than ammoniated straw(P>0.05).Economic benefits,the rate of weight gain of silage maize and ammoniated straw are better than the straw group.
