【摘要】 为研究红安格斯牛对大别山牛的杂交改良效果，对大别山牛、安大（安格斯牛×大别山牛）F₁牛和F₂牛不同年龄段的生长性能、成年牛的屠宰性能等进行了测定和分析。结果表明，安大F₁牛在初生、6月龄、12月龄、24月龄时的体尺和体重均极显著高于同龄大别山牛（P<0.01），安大F₁牛和F₂牛的胴体重、净肉重均高于大别山牛且差异显著（P<0.05）。说明红安格斯牛对大别山牛的杂交改良效果较好，可以提高大别山牛的生产性能。更多还原

【Abstract】 In order to study the crossbreeding improvement effect of Red Angus cattle on Dabieshan cattle,the growth performance of Dabieshan cattle,F₁and F₂generation of Anda hybrid cattle（Angus cattle×Dabieshan cattle）at different age and slaughter performance of adult cattle were measured and analyzed.The result showed that the weight and body size of F₁generation of Anda hybrid cattle at the age of born,6 months,12 months and 24 months were higher than those of Dabieshan cattle（P<0.01）,and the carcass weight and net meat weight of F₁and F₂generation of Anda hybrid cattle were higher than that of Dabieshan cattle（P<0.05）.This indicated that Red Angus cattle could improve Dabieshan cattle better,which could improve the production performance of Dabieshan cattle.更多还原
