摘要
为探讨德国肉用美利奴杂交F1代肉羊在舍饲、放牧补饲和全放牧条件下的肥育效果,进行了不同饲养方式的肥育试验。试验结果表明:舍饲组育肥体重平均为47.25kg,比放牧补饲和放牧对照组分别提高了22.60%和28.13%,差异极显著(P<0.01)。经屠宰测定和胴体分割测定:舍饲组屠宰率、净肉率为51.29%和43.19%,比补饲组和对照组分别提高4.57、8.21和4.65、7.58个百分点。舍饲组每只羊平均多盈利30～50元。
To discuss the effects of breeding F1 Sheep using Germen meat in housing breeding, pasturage breeding and pure pastuage breeding, the different breeding experiments has been made. The result shows： the average weight is 47.25 kilograms in housing breeding, 22.60% and 28.13% higher than pasturage with feed group and pure pasturage group （significanse level P〈0.01） . Butchering test and body test results show： butchering rate and pure meat rate are 51.29% and 43.19% in housing breeding group, 4.57% , 8.21% and 4.65% , 7.58% higher than pasturage with feed group and control group, the average profit is 30-50 yuan per sheep in housing breeding group.
