摘要
为了研究性别对查吾拉地区牦牛的产肉性能及肉营养成分的影响,随机选取8岁健康的查吾拉牦牛10头,公母各半,对不同组别间牦牛进行屠宰试验比较肉营养品质的差异。结果表明,母牦牛屠宰率、净肉率、胴体率、骨肉比均高于公牦牛,但无统计学差异。肉营养成分分析结果显示,母牦牛肉中维生素A、E、B12、半胱氨酸、组氨酸、精氨酸、钙、硒、脂肪酸含量高于公牦牛(P<0.05)。研究结果表明,查吾拉牦牛富含较高的营养成分,可为人类提供优质健康的动物蛋白,具备作为优质牦牛肉源生产的潜力。相比较,母牦牛肉优于公牦牛。
In order to research the slaughter performance and meat quality of yak cows in Cha Wula district,ten 8-year-old yaks(5 males and 5 females)were randomly selected to determine slaughter performance and muscle quality.It was found that the female yaks had a higher dressing out percentage,net meat yield,and bone-meat yield than males.However,the eye muscle in male yak was of greater diameter than in the females.The analysis of nutrient composition of yaks showed that the contents of vitamin A,E,B 12,cysteine,histidine,arginine,calcium,selenium and fatty acids in male yaks were higher than those in female yaks(P<0.05).The results showed that Cha Wula yak meat is rich in highly nutritional components,and therefore is able to provide high quality animal protein for human consumption.In conclusion,compared with male yak meat,female yak meat is superior.
