摘要： 试验旨在探讨年龄和性别对陶×寒F1羔羊肉用性能及肉品质的影响。选取同等饲养条件下的7月龄陶×寒F1公羔、母羔；13月龄陶×寒F1公羔各5只，研究其屠宰性能和肉的食用品质。结果表明，13月龄羔羊的宰前活重、胴体重比7月龄高41.85%、56.51%（P<0.01），屠宰率显著高于7月龄（P<0.05），13月龄羔羊的屠宰性能高于7月龄。产肉力指标上13月龄羔羊的瘦肉重、眼肌面积、肉骨比较7月龄高30.40%、30.04%（P<0.01）、15.56%（P<0.05）。13月龄羔羊肥肉重、GR值比7月龄高117.23%、263.40%（P<0.01）。肉品质方面，13月龄羔羊背最长肌剪切力值、滴水损失率、胶原蛋白含量、肌纤维直径均显著高于7月龄（P<0.05）。公羔的宰前活重、胴体重比母羔高11.96%、14.36%（P<0.05），表明7月龄时公羔屠宰性能高于母羔，肉品质指标无显著差异。因此，陶×寒F1羔羊的屠宰性能和肉品质明显受年龄、性别的影响。

Abstract: The effects of slaughter age and sex on lamb meat performance and quality of Poll Dorset × Small Tail Han Sheep F1 were studied. Five male lambs, 5 female lambs of 7monthold and 5 male lambs of 13monthold, fed under the same feeding conditions, were slaughtered to study slaughter characteristics and meat quality. The live weight and carcass weight of the 13monthold lamb were higher 41.85%（P<0.01）and 56.51%（P<0.01）than that of the 7monthold respectively. The dressing percentage of 13monthold lamb was significantly higher than 7 months (P<0.05), it showed that 13monthold lamb on slaughter characteristics was higher very markedly than 7monthold. The lean meat weight, eye muscle area and meatbone ratio were higher 30.40% (P<0.01), 30.04% (P<0.01) and 15.56%(P<0.05) than that of the 7monthold respectively. The GR value and fat weight of 13monthold were higher 117.23% (P<0.01) and 263.40% (P<0.01) than 7monthold lamb. The shear force value, drip loss, collagen content and muscle fiber diameter of 13monthold were significantly higher than 7monthold Lamb (P<0.05). The live and carcass weight of male lamb were higher markedly than female (P<0.05), but the fat percentage of female was significantly higher 11.96% (P<0.05) and 14.36% (P<0.05) than that of male. Results showed that slaughter age markedly affected slaughter characteristics and meat quality of lamb, and sex affected slaughter characteristics of lamb. 
