玉米秸秆微贮饲料饲喂育肥牛试验

Test on Corn Straw Microbiological Fermented Feed Feeding Fattening Cattle

[目的]通过本试验探讨玉米秸秆微贮饲料饲喂夏西黄育肥牛的效果。[方法]选择12～18月龄、生长发育正常、个体大小相近的夏西黄公牛24头,随机分为试验组和对照组,每组12头。在相同饲养管理水平,相同精料水平下,对照组饲喂普通玉米秸秆,试验组饲喂微贮玉米秸秆饲。[结果]试验组肉牛在试验期内头均日增重0.885kg,比对照组0.703kg提高0.182kg,差异显著(P<0.05)。试验组牛头均日盈利4.81元,比对照组高2.21元,差异极显著(P<0.05)。[结论]玉米干秸秆经微贮处理,不仅可以提高育肥牛增重效果,而且可以明显提高饲料报酬,降低饲养成本,提高肉牛养殖经济效益。

[Objective]To investigate the fattening effect of corn straw microbiological fermented feed on Xia-xi yellow cattle. [Method]24 Xia Xi yellow bulls at 12-18 months age with normal growth and de- velopment, similar size were randomly divided into experimental group and control group, each group was 12. Under the same feeding and management and the same concentrate level, the control group was fed nor- mal corn straw, the test group fed microbiological fermented corn straw feed. [Result]The daily weight gain per head in test group during the trial period was 0. 885 kg,which increased 0. 182kg. The difference between them was significant （P〈0.05）. The mean daily profit in test group was 4.81 yuan,which was 2.21 higher than that of the control group,and the difference was significant （P〈0.05）. [Conclusion]The corn straw by microbiological fermented process not only could improve the weight gain for fattening cattle,but also could significantly improve the feed remuneration, reduce feed cost and improve the economic benefit for breeding beef cattle.
