饲用甜高粱青贮饲喂肉牛的增重效果试验

摘要

In order to explore the possibility of Forage Sorghum ( Sorghum bicolor (L.) Moench ) for silage and to enrich the silage source , twenty-seven crossbred beef cattles of the same variety ,born at the same birth and similar body weight ,were randomly divided into 3 treatments . The feeding effects of the three groups including forage sorghum silage, corn stover silage and whole corn silage . Results showed that: To campare with the second and the third group The weight was increased 44.37% and 7.8% and the daily revenue of the first group was increased 93.49% and 29.64%. Therefore, forage sorghum could be valuable as an alternative forage crop for beef cattle fattening.It can replace the traditional silage such as corn stover silage and whole corn silage.%为探索饲用甜高粱(Sorghum bicolor ( L.) Moench)用作青贮饲料的可能性,丰富饲料作物来源,该实验选取品种、月龄一致、体质量相近，27头杂交肉牛，随机分为3组进行对比分析，其中1、2和3分别饲喂饲用甜高粱青贮、玉米秸秆青贮和全株玉米青贮。结果表明：1组增质量分别比2和3组提高44.37%和7.8%，头均日收益分别提高93.49%和29.64%。饲用甜高粱用作青贮作物有很大的利用价值，因此完全可以替代目前常用的玉米秸秆和全株玉米等青贮原料用于养牛。
