摘要
[目的]为了获得当地更为实用可行的肉牛育肥饲料。[方法]试验分3个组,试验Ⅰ组,是榆阳区当地养牛户传统的喂牛饲料;试验Ⅱ组,饲料以干玉米秸秆为主要粗饲料+精料补充料;试验Ⅲ组,饲料以玉米青贮饲料为主要粗饲料+精料补充料。试验对3种不同类型饲料育肥西门塔尔肉牛的日增重、料重比和增重成本进行比较。[结果]Ⅰ组、Ⅱ组和Ⅲ组的日增重分别为(1.24±0.26)kg、(1.26±0.14)kg和(1.32±0.19)kg,Ⅲ组>Ⅱ组>Ⅰ组,三组之间差异均不显著(P>0.05);料重比分别为7.53、7.46和6.99,Ⅰ组>Ⅱ组>Ⅲ组;增重成本分别为17.17元/kg、18.28元/kg和19.42元/kg,Ⅲ组>Ⅱ组>Ⅰ组。[结论]青贮日粮组(Ⅲ组)的增重效率最高;传统日粮组(Ⅰ组)的成本最低。
[Objective]This experiment was conducted to compare the daily gain,feed to gain ratio and weight gain cost of Simmental beef cattle fattening with different types of feed,in order to obtain more practical and feasible fattening feed for local beef cattle.[Method]The experiment was divided into three groups:experimental groupⅠ,which was the traditional feed of local cattle farmers in Yuyang District.Experimental groupⅡ,dry corn straw as the main roughage+concentrate supplement.Experimental groupⅢ,corn silage was the main roughage+concentrate supplement.[Result]The results were as follows:the daily gain of groupⅠ,groupⅡand groupⅢwere(1.24±0.26)kg,(1.26±0.14)kg and(1.32±0.19)kg,respectively,groupⅢ>groupⅡ>groupⅠ,and there was no significant difference among the three groups(P>0.05).The ratio of feed to gain were 7.53,7.46 and 6.99,respectively,and groupⅠ>groupⅡ>groupⅢ.The cost of weight gain were 17.17 yuan/kg,18.28 yuan/kg and 19.42 yuan/kg,respectively,in groupⅢ>groupⅡ>groupⅠ.[Conclusion]The results showed that:the weight gain efficiency of silage diet group(groupⅢ)was the highest,the cost of traditional diet group(groupⅠ)was the lowest.
