摘　　要：为筛选适宜的杂交组合,提高牛肉品质,选取发育正常,健康无病,经过育肥的24个月龄夏和杂一代牛和纯种夏南牛各6头(均为阉牛)进行屠宰测定,比较夏和杂一代牛(日本黑毛和牛♂×夏南牛♀,F_1)与纯种夏南牛的牛肉品质。结果显示:(1)在营养成分含量方面,夏和杂一代牛的眼肌脂肪含量为17.72%,显著高于纯种夏南牛的脂肪含量5.49%(P<0.05),水分含量为60.84%,显著低于纯种夏南牛(P<0.05),但纯种夏南牛的眼肌蛋白质含量(23.39%)显著高于夏和杂一代牛(P<0.05)。(2)在肉质指标方面,夏和杂一代牛的眼肌剪切力显著低于纯种夏南牛(P<0.05),滴水损失和蒸煮损失显著高于纯种夏南牛(P<0.05),眼肌面积显著低于纯种夏南牛(P<0.05),2组牛的眼肌pH值差异不显著(P>0.05)。综上,夏和杂一代牛的眼肌脂肪含量和嫩度显著好于纯种的夏南牛,而眼肌面积、滴水损失及蒸煮损失不如纯种夏南牛。In order to compare the beef quality traits between Xia×He F1cattle（ Japanese black beef cattle × Xianan） and Xianan cattle,6 cattles of Xia×He F1 and 6 cattles of Xianan cattle,which grew normally,healthy and disease-free were slaughtered after 24 months high-intensity fattening to measure the rib-eye beef quality traits of Xia×He F1 and Xianan cattle.The results were as follows.（ 1） In the nutritional characteristics of beef,the fat content of Xia×He F1 beef was 17.72%,significantly higher than that of Xianan beef,which was5.49%（ P〈0.05）,the moisture content of Xia×He F1 beef was 60.84%,significantly lower than that of Xianan beef（ P〈0.05）,the protein content of Xianan beef（ 23.39%） was significantly higher than that of Xia×He F1beef（ P〈0.05）.（ 2） In meat quality properties of beef,the indexes of the shear force,cooking loss,eye muscle area of Xia×He F1 beef was significantly lower than that of Xianan beef（ P〈0.05）.And the drip loss（ 1.46%）of Xianan cattle was significantly better than that of Xia×He F1（ P〈0.05）; but there was no significant difference in pH between Xia×He F1 and Xianan cattle（ P〉0.05）.In conclusion,the beef quality of Xia×He F1 was significantly better than that of Xianan cattle,therefore,the crossbreeding of Japanese black beef cattle and Xianan cattle can significantly improve the beef quality of Xianan.
