摘　　要：测定和分析了郭尔罗斯细毛羊１０月龄肥育公羔肉用性能及肉质，同时与东北细毛羊进行对比。经６个月育肥后，郭尔罗斯细毛羊平均日增重为１３１．２２ｇ，东北细毛羊平均日增重为１０４．８９ｇ；郭尔罗斯细毛羊主要器官重量（Ｐ＜０．０５）、１０月龄体重、宰前活重、胴体重、净肉重、屠宰率、净肉率、骨肉比（Ｐ＜０．０１）明显高于东北细毛羊；主要肉块营养成分与东北细毛羊无明显差异（Ｐ＞０．０５）；肉质ｐＨ值、失水率、熟肉率与东北细毛羊无明显差别（Ｐ＞０．０５），而眼肌面积明显高于东北细毛羊（Ｐ＜０．０１）。Fattening performance and mutton quality of 10monthold Hoggets in the Guoerluosi Finewool Sheep (GFS) were studied in this paper, compared with those in the Northeast Finewool Sheep (NFS). After 6 month fattening, average liveweight gain per day were 131.22g and 104.89g for GFS and NFS, respectively. The weights of main body organs (P<0.05), liveweight, liveweight before slaughtering, carcass weight, meat weight, dressing percentage, meat percentage (MP) and ratio of bone to meat (RBM) in GFS (P<0.01) were significantly higher than those in NFS. Nutrient composition of carcass in GFS were not significantly different from those in NFS. pH, waterlosing percentage, ripening percentage (P>0.05) were not different from, but eye muscle area of GFS (P<0.05) was significantly higher than those of NFS.
