摘要: 为分析自然放牧条件下戈壁羊和察哈尔羊羊肉品质, 对12月龄各品种羊屠宰性能、肱三头肌、背最长肌和股二头肌部位物理指标和营养成分进行测定。结果表明:察哈尔羊的活重和胴体重表现出良好优势(P<0.05), 而戈壁羊屠宰率显著(P<0.05)高于察哈尔羊;察哈尔羊羊肉的L*值和a*值最大, 熟肉率为39.59%~45.94%, 色泽和保水性优于戈壁羊;戈壁羊羊肉剪切力为7.16~8.47 N, 肉质鲜嫩柔软, 戈壁羊和察哈尔羊羊肉的蛋白质含量分别为17.63%~19.54%和17.18%~18.77%, 氨基酸总量分别为70.73%~75.98%和67.29%~70.86%, 戈壁羊羊肉的营养价值略优于察哈尔羊。

Abstract: This study was conducted to evaluate and compare the mutton quality of Gobi sheep and Qahar sheep raised under natural grazing conditions. The slaughter performance as well as the physical indicators and nutritional components of the triceps brachii, longissimus dorsi and biceps femoris of the 12-month-old Gobi sheep and Qahar sheep were determined and statistically compared. The results showed that Qahar sheep had significantly (P<0.05) higher live weight and carcass weight compared to Gobi sheep, while Gobi sheep had significantly (P<0.05) higher slaughter rate; higher L* and a* values were observed in Qahar sheep meat, the cooked meat rate of Qahar sheep ranged from 39.59% to 45.94%, and Qahar sheep meat had better performance in color and luster as well as water retention property; Gobi sheep meat was tender and soft, with the shear force of 7.16-8.47 N; the protein content of Gobi sheep meat and Qahar sheep meat were 17.63%-19.54% and 17.18%-18.77%, respectively, and the total amino acids content were 70.73%-75.98% and 67.29%-70.86%, respectively. In conclusion, the meat nutritional value of Gobi sheep is slightly better than that of Qahar sheep.
