【摘要】：[目的]为研究香蕉茎叶青贮营养价值和饲喂安格斯牛的育肥效果。[方法]本试验开展了香蕉茎叶与稻草混贮的营养价值评定和饲喂18月龄、24月龄两个阶段安格斯牛舍饲育肥试验。[结果]表明:利用香蕉茎叶以"70%香蕉茎叶+29%干稻草+1%玉米面"比例混贮的青贮外观评定达到优良标准;常规营养成分测定指标说明混合青贮的营养价值高。利用该香蕉茎叶青贮饲喂两个月龄段的安格斯牛,经过60d育肥期,两组牛的育肥效果明显,其中18月龄组的总增重和平均日增重分别比24月龄组高20.07kg和0.33kg,增重效果显著(P0.05),18月龄组的纯收入比24月龄组高569.86元。[结论]香蕉茎叶青贮制作技术简单,青贮品质好,用于饲喂安格斯牛可显著提高增重和养殖效益。
[Abstract]:[objective] to study the nutritional value of banana stem and leaf silage and the fattening effect of feeding Angus cattle. [methods] the nutritional value evaluation of banana stem and leaf mixed with rice straw and feeding experiment of Angus cattle at 18 months and 24 months of age were carried out in this experiment. The results showed that the silage appearance of banana stem and leaf mixed with "70% dry rice straw 1% corn flour" ratio reached good standard, and the nutritional value of mixed silage was high. The silage of banana stem and leaf was used to feed Angus cattle of two months of age. After 60 days of fattening, the fattening effect of the two groups was obvious. The total weight gain and average daily gain of 18-month-old group were higher than that of 24-month-old group (20.07kg and 0.33 kg, respectively). The net income of 18-month-old group was 569.86 yuan higher than that of 24-month-old group (P0.05). [conclusion] the processing technique of banana stem and leaf silage is simple and the silage quality is good.
