摘要
对德国肉用美利奴羊(父本)与本地绵羊二元杂交后代羔羊的生长发育、产肉性能以及多胎基因等进行了研究。结果表明,2013年和2014年德×本F1杂交羔羊在当地的舍饲适应性、生长发育和产肉方面均表现出杂种优势,尤其是2014年6月龄德×本F1平均体重达到44.24 kg,比对照组高7.02 kg,差异极显著(P<0.01),且其瘦肉率高、羊肉品质好;经过短期育肥的6月龄杂种羔羊胴体重比对照组提高了6.28 kg,净肉率、屠宰率分别比对照组提高了5.11%和6.92%,差异显著(P<0.05)。
In this study, the meat production performance of the F~ generation hybrid sheep of German Mutton Merino sheep and local sheep was evaluated. The result showed that the hybrid sheep have the heterosis in terms of adaptability to the local confinedness condition, growth and development and meat production performance in 2013 and 2014. The average weight of F~ generation of the hybrid sheep in 6 months old was 44.24 kg and was significantly higher than that of the control group （P〈0.01）, and lean meat percentage was higher and mutton quality was better in 2014. The carcass weight of F1 generation in 6 months old was 6.28 kg higher than that of control group, and the meat percentage and dressing percentage of the F1 generation was 5.11% and 6.92% higher than those of the control group respectively （P〈0.05）.
