在氨化稻草日粮中用酒糟粉替代玉米对黄牛的增重试验

An Experiment of Using Distilled Grain Powder as a Substitute for Corn to Increase Beefs Weight through Feed them together with Ammoniated Rice Stra

选用５０头１５～１８月龄黄牛，研究氨化稻草日粮中用酒糟粉替代玉米对日增重的影响。结果表明，添加酒糟粉的试Ⅰ组比添加玉米粉的试Ⅱ组每头日增重高１１．６ｇ，但差异不显著（Ｐ＞０．０５），全期纯增收入１９４．０７元，增加３．６９倍，差异极显著（Ｐ＜０．０１）；试Ⅰ组比对照组每头日增重高出２３０ｇ，提高４６．６％，差异极显著（Ｐ＜０．０１），纯增收入２０７．５６元，增加５．３倍，差异极显著（Ｐ＜０．０１）。单纯使用氨化稻草饲喂肉牛效果不佳。

In this experiment, 50 cattles are chosen to feed with distilled grain powder as a substitute for corn togecher with ammoniated straw to increase the daily gain and to reasearch the influence on economic performance. 40 heads of cattle were randomly chosen and divide into 2 groups, and each with 2 replicates, and remain 10 cattles as the CK group.the results showed that,for Group Ⅰwhich fed with the distilled grain powder in contrast to Group Ⅱ which was fed with the corn powder, every cattles daily gain increased more than 11 6g, no significant defference was found(P>0 05). The net income increased by 194 07 yuan/head.which was 3 69 times of the CK(P<0 01) The daily gain for Group Ⅰ was 230g higher than CK. increased by 46 6% (P<0 01). But only use ammoniated rice straw as the diet of the cattle could not result in good efficiency.
