摘  要:
将玉米秸秆揉切加工经氨化、微贮、青贮处理后进行饲喂肉牛增重肥育试验。对照组牛喂自然风干揉碎秸秆。 40头供试牛随机分为 4组 ,分别进行对比 ,其结果为 :喂青贮秸秆组头日均增重 1 0 73g,喂微贮秸秆组头日均增重 986g,喂氨化秸秆组头日均增重931 g,对照组头日均增重 684g。青贮组与微贮组、氨化组差异显著 ( P<0 .0 5 ) ,与对照组差异极显著 ( P<0 .0 1 )。微贮组与氨化组差异不显著 ( P>0 .0 5 )。微贮组、氨化组与对照组差异极显著 ( P<0 .0 1 )。将各组所耗精料、粗料及增重按当时市场价格进行分析。 60天试验期结束 ,青贮组、微贮组、氨化组、对照组平均每头获利分别为 1 2 4 .86元、92 .2 1元、90 .5 2元和 2 3.5 4元。玉米秸秆青贮处理后饲喂肉牛 ,优于秸秆微贮和氨化 ,更好于干秸秆 ,且操作简单 ,适口性强 ,饲喂效果明显 ,在广大农区值得大力推广。

摘  要:
cattle were randomly divided into 4 groups, one was the control group fed with rolled dry corn straw, the rest 3 groups were fed with corn straw silage, microbial fermentation corn straw and ammoniated corn straw, respectively. The results showed that the finishing effects of corn straw silage were significantly higher than that of microbial fermentation corn straw, ammoniated corn straw (P<0.05) and control group(P<0.01), average daily gain of the 4 groups were 1073g, 986g, 931g and 684g, respectively. There was no significant different between the average daily gain of the group fed with ammoniated corn straw and microbial fermentation corn straw(P>0.05), which were both higher than that of the control group(P<0.01). Average economic income per cattle of the 4 groups were $124.86, $92.21, $90.52 and $23.54, respectively.
