摘　　要：为了探讨高原放牧条件下不同杂交后代的肉用品质,以白萨福克、特克塞尔、邦德、澳洲美利奴为父本,以甘肃高山细毛羊为母本杂交生产羔羊肉(分别设为Ⅰ、Ⅱ、Ⅲ和Ⅳ组)。选择4个杂交组合周岁羔羊各5只,开展屠宰测定和肉质分析。结果表明,引入品种可以明显提高甘肃高山细毛羊的产肉力,4个组合中萨×甘组、澳×甘组改良效果最为显著,白萨甘细的肌肉分级标准判定其为TM级,脂肪含量略高,澳甘细和特甘细均为PME级,邦甘细为PL级。In order to discuss the mutton quality of different hybrid progeny under the condition of grazing in the plateau, White Suffolk, Texel, Bond and Australia Merino were used as male parent, and Gansu Alpine Merino were used as female parent to produce mutton through hybridization（set up separately for groupⅠ,Ⅱ,Ⅲ and Ⅳ）.Each group has five lambs. Hybrid yearling lambs of four combinations were selected to carry out the experiment of slaughter measurement and mutton analysis. The results showed that introduced varieties can obviously improve the mutton performance of Gansu Alpine Merino.GroupⅠand Ⅳ of four hybrid combinations were the most significant improvement. The muscle level of groupⅠwas evaluated as TM level, which the fat content was a little bit high. The muscle level of group Ⅳ and Ⅱwere evaluated as PME level, and groupⅢ as PL level.
