| 摘 要： | 选择通江本地黄牛25头,随机分为A、B、C、D、E组,每组5头,A组采用传统舍饲肥育方式,B、C、D、E组分别采用在传统舍饲基础上以不同方式补饲低精料的肥育方式;试验结束时,每组选2头牛进行屠宰测定。结果发现:B、C、D、E组日增重分别比A组(对照组)提高218.8%(P<0.01)、250.3%(P<0.01)、243.8%(P<0.01)、225%(P<0.01),肥育毛利润分别比A组多出8.4元/头、11.9元/头、14.4元/头、6.0元/头,屠宰性能与A组无显著差异(P>0.05)。以上结果表明:与A组相比,B、C、D、E组(特别是D组)能显著提高日增重,缩短肥育时间,增加收入,且对屠宰性能无显著影响,是通江本地黄牛低精料肥育的较好方式。

| Abstract: | Twenty-five yellow cattle were selected and randomly divided into five groups. And there were five cattle in each group. Control group A was used traditional feedinglot. Group BCD and E were fed different concentrates except traditional feedinglot .At the termination of feeding trial 2 cattle were selected and were slaughtered to evaluate carcass quality .The relusts showed as following by contrast to that of group A average daily gain ADG of Group BCD and E improved 218.8%P<0.01250.3%P<0.01243.8%P<0.01 and 225.0%P<0.01 respectively gross profits improved 8.4yuan11.9yuan14.4yuan and 6.0 yuan respectively carcass quality hadn't marked difference P>0.05. It was recommended that Group BCD and E special group D could promote remarkably ADG reduce fattening time and add to income by contrast to that of group A. It will be a good fattening way of QuXian local yellow cattle. |
