不同氨化玉米秸秆日粮对羔羊育肥效果的影响

The Effect of Different Ammoniated Corn Straw Diet to the Fattening Hybrid Lamb

试验研究了不同水分氨化玉米秸秆日粮对杂交羔羊舍饲育肥效果的影响。结果表明,加水45%氨化玉米秸秆日粮的日增重最高,与其他3组差异显著(P<0.05),加水65%氨化玉米秸秆日粮与加水25%氨化玉米秸秆日粮之间差异不显著(P>0.05);就料重比和生产成本而言,不同水分氨化玉米秸秆饲粮组之间差异极显著(P<0.01),加水45%氨化玉米秸秆日粮的料重比分别比加水65%、25%、未加水氨化玉米秸秆饲粮低0.32、0.51、1.13,生产成本分别节约了0.47、0.75、1.66元。

The experiment studied the effect of different moisture ammoniated corn straw diet to the drylot feeding fattening hybrid lamb.The result showed that the group which fed 45% moisture ammoniated corn straw had the highest dialy gain,and had a significant difference with the other three group（P0.05）.There was no singificnat difference from the group fed 65% moisture ammoniated corn straw and the group fed 25% moisture ammniated corn straw.The anharmonic ratio and the cost from the different moisture ammoniated corn straw was great significant（P 0.01）.The anharmonic ratio of the 45% moisture ammoniated corn straw was lower about 0.32,0.51,1.13 than the other three groups,and the cost was lower about ￥0.47,￥0.75,￥1.66.
