青贮玉米型全混合日粮饲喂肉牛试验报告

Study On Silage Corn Total Mixed Ration Feeding Beef Cattle

为测定以陕西省榆林市当地原料为主配制的青贮玉米型全混合日粮的饲喂效果,笔者选择西门塔尔杂交牛14头,按体重相同或相近的原则配对分组后开展试验。试验组饲喂青玉米型全混合日粮,对照组饲喂当地传统的“低质粗饲料+精料型”日粮。达到相同出栏体重800kg,饲养时间试验组需366d,对照组需460d缩短94d;日增重试验组1510±110g,对照组1200±126g,提高25.83%(P<0.05);单位饲料成本试验组15.52元,对照组18.87元,降低了3.35元。试验结果表明,青贮玉米型全混合日粮饲喂肉牛增重快、饲料利用率高、经济效益好,值得推广。

[Objective]To test the feeding effect of silage corn total mixed ration produced from local raw materials.[Methods]20 Simmen-tal hybird cattle with similar body weight were selected and randomly divided into test group and control group.The test group fed corn silage total mixed ration,and the control group fed the local traditional"low quality roughage+large concentrate"diet.[Results]The re-sult showed that the feeding time of the test group and the control group were 366 d and 460 d when reach the same weight of 800 kg.It's 94 d shortened;The average daily gain was 1510±110 g in the test group and 1200±126 g in the control group,which was increased by 25.83%(P<0.05);The feed cost of test group and control group were 15.52 yuan and 18.87 yuan,decreasing by 3.35 yuan.[Conclusion]The feeding effect by silage corn total mixed ration was better than traditional ration,which could improve weight gain rate and feed re-ward.And the economic benefit was high.Silage corn total mixed ration could be popularized and applied in the future.
