【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。更多还原
