摘　　要：本研究对多浪羊×塔什库尔干羊×萨福克羊三元杂交后代羔羊的生长发育和产肉性能等进行研究分析,结果表明,多×塔×萨三元杂交羔羊在当地的舍饲适应性、生长发育速度、强度和产肉性能等方面表现出一定的杂种优势,6月龄Fl羔羊平均体重达到42.30kg,比同龄土种羔羊高6.30kg,差异极显著(P<0.01),而且其瘦肉率高,胴体重品质好;经过短期育肥的6月龄杂种羔羊胴体重、净肉率、屠宰率分别比土种羔羊提高了6.15千克、3.14%和7.5%差异极显著(P<0.01);后腿净肉增加1.695kg,提高了32.13%,差异极显著(P<0.01)。In this study, the Hybrid sheep between Duolang xTashkorgan and Suffolk have the batter advantages in terms of growth and development, at the same time it has a high lean meat percentage, meat quality is good, especially the average weight of F1 in six months old can be can be achieved 42.30 kg, higher than their peers of local sheep F1 for about 6.30 kg, the result was extremely significant difference （P〈0.01）. The carcass weight,dressing percentage and net meat rate of 6- month- old suffolk cross lambs which were fattening after a short while increased , respectively, 6.15 kg,7.5% and 4% than the local hybrid F1- generation,the result was extremely significant difference （P〈0.01）; hind legs net meat increased 1.695 kg, increased 32.13%.
