| 摘 要： | 目的]比较不同饲喂方法对肉牛育肥的影响,为肉牛育肥方法的选取提供参考依据。方法]选用40头体重相近的育肥公牛,随机分成试验组和对照组,在试验组使用TMR饲喂方式,对照组使用先粗料后精料的饲喂方法,进行两种饲喂方法对育肥牛产肉性能、饲料报酬和经济效益的分析比较。结果]对照组试验全期增重和日增重极显著高于试验组(P<0.01),试验组每增重1 kg消耗干物质10.76 kg,对照组仅为8.35 kg,对照组头均多收益为383.24元。结论〗采用先粗料后精料的饲喂方式对肉牛育肥更合适。

| Abstract: | Objective]To compare the effects of different feeding methods on the fattening of beef cattle and provide reference for fattening beef cattle.Method]A total of 40 fattening beef cattle of similar weight were randomly divided into experimental and control groups,and feeding in the way of total mixed ration(TMR) and roughage-concentrate diet,respectively.Meat production performance,feed conversion and economic benefits in different groups were then compared.Result]The weight gain and daily gain of the control group were significantly higher than that of the test group(P<0.01).The weight of beef cattle increasing 1 kg would consumed 10.76 kg dry matter in experimental group,but only 8.35 kg in control group.Moreover,each beef cattle in contral group can gain 383.24 yuan more than experimental group.Conclusion]Roughage-concentrate diet is more appropriate to feed beef cattle for fattening. |
