全株玉米青贮料喂育肥牛的试验

Finshing Effects of Whole Corn Silage Fed to Beef cattle

选用体重相近的鲁本和秦本杂交牛24头,随机分为2组(每组12头),分别饲喂全株玉米青贮料(试验组)和干玉米秸秆(对照组),观察全株玉米青贮料饲喂育肥牛的效果。结果表明,试验组牛育肥期平均日增重较对照组提高了46.2％(P<0.01),试验组牛和对照组牛每增重1 kg消耗精粗饲料量分别为1.052 kg、8 kg和3.174kg、10.16 kg;分析盈利情况,试验组牛较对照组牛平均每头多盈利40.73元(P<0.01),表明全株青贮玉米喂牛,饲料报酬高,经济效益好,应大力推广。

Twenty four crossbred beef cattle were allotted in two groups and fed corn silage or dry corn straw, respectively. Results showed that average daily gain of the cattle fed corn silage were higher than that of the other group by 46. 2 percent (P<0. 01). Concentrate and forage intake for 1 kg weight gain were 1. 052 kg, 8. 0 kg and 3.17 kg, 10. 16 kg, respectively, profit per cattle fed with corn silage were higher than that of the other group for $ 40. 73 (P< 0. 01), which showed corn silage, as a good forage source for beef cattle should be widely extended.
