微贮玉米秸肥育秦杂牛的效果对比试验

Effects of Fattening Qin Crosses with Microbial Corn Stalk Silage

随机将２～３岁未去势秦杂公牛２６头分为两组，在精料相同情况下，在３９天内分别饲喂以风干玉米秸（对照组）和微贮玉米秸，观察微贮玉米秸对秦杂牛的育肥效果。试验结果：微贮组与风干组头平均日增重分别为１１４４ｇ和９０２ｇ，差异极显著（ｐ＜０．０１）；微贮组牛每增重１ｋｇ比风干组少耗精料１．１４ｋｇ，降低成本１．０８元；饲喂微贮玉米秸较饲喂风干玉米秸平均每头牛可增加收入１０９．５１元。结果表明：利用微贮玉米秸肥育肉牛，可节省精料、降低成本、提高经济效益，其可作为肉牛的常年基础饲料。

male Qin Crosses with the age between 2 to 3 year-old were randomly divided into two groups at the same concentrate level, one group received microbial corn stalk silage and the other group received air dry corn stalk as control. during 39 days experimental period to investigate fattening result for Qin Crosses .There was a significant differences (p<0.01)in average daily gain between treatment and control group (1144g vs 902g);every 1 kg gain of animals in treatment group consumed 1.14 kg concentrate and cost 1.08 RMB yuan less than control group;feeding microbial corn stalk silage could earn 109.51 RMB yuan per head more than feeding corn stalk. The result showed that fattening beef with microbial corn stalk silage could save concentrates, cut the cost and increase economic return, the microbial corn stalk silage can be used as a year round basic feeds for beef cattle .
