不同方法处理麦秸对肉牛饲喂效果的研究

Feding Effect in Different Treatment of Wheat Straw to Beef

肉用公牛 1 5头 ,分成试验Ⅰ、Ⅱ、Ⅲ和对照Ⅰ、Ⅱ 5个组。各组精料用量与营养水平相同。粗饲料用不同方法处理的麦秸。试验Ⅰ组饲用EM发酵剂发酵的麦秸。试验Ⅱ组饲用EM发酵剂喷洒的麦秸 ,试验Ⅲ组饲用干麦秸并以EM发酵剂饮水。对照Ⅰ组饲用氨化麦秸。对照Ⅱ组仅喂干麦秸。试验 6 1天。结果试验Ⅰ、Ⅱ、Ⅲ和对照Ⅰ组牛 ,分别比对照Ⅱ组提高增重 45 .99% (P <0 .0 1 )。 8.72 % (P >0 .0 5 )、3.1 3% (P >0 .0 5 )和 44 .76 %(P <0 .0 1 )。试验Ⅰ组增重与对照Ⅰ组相当 ,但处理费用仅为对照Ⅰ组的 1 / 3。证明用EM发酵麦秸饲喂肉牛是很有意义的。

Fifteen head of beef bull were divided into five group by test Ⅰ、Ⅱ、Ⅲand control group Ⅰ、Ⅱ.Every group were all the same for concentrates and nutrient level.Roughages were air dry wheat straw in different treatment.Test Ⅰ group were feeded wheat straw sprinkled EM fermented preparation.Test Ⅲ group were feeded air dry wheat straw and drunk EM fermented preparation.Comparison Ⅰ group were feede ammonniated wheat steaw.Comparison Ⅱ group were only feeded air dry wheat straw.It was tested 61 days.The result as compared with control Ⅱ,test Ⅰ、Ⅱ、Ⅲ and control Ⅰgroup beeves weight increased 45.99%(P<0.01)、8.72(P>0.05)、3.13%(P>0.05) and 44.76%(P<0.01),respectively.Test Ⅰ group beedves increased weight correpond to control Ⅰ,but test 1 expenses with 1/3 control 1.It have been proved to be very significant that feeded fermented wheat strow with EM to beeves.
