中文摘要:
      通过分析金川多肋牦牛乳的营养成分, 为种质遗传特性及乳品加工研究积累资料. 随机选取金川牦牛、麦洼牦牛泌乳期母牛各30头, 采用ICP-OES测定乳矿物质含量, GS-MS测定脂肪酸含量, 乳成分测试仪测定乳常规成分. 结果显示: 金川多肋牦牛乳常规成分的非脂固、蛋白质、密度、乳糖显著高于麦洼牦牛(P<0.01); 金川多肋牦牛乳矿物质元素与麦洼牦牛差异不显著; 脂肪酸中硬脂酸、亚油酸、油酸含量高于麦洼牦牛(P<0.05或P<0.01). 金川多肋牦牛乳部分成分指标优于麦洼牦牛, 具有一定特异性.
英文摘要:
      Jinchuan multiple-rib yak milk’s nutritional components were analyzed to accumulate basic data for the study of yak genetic characteristics and dairy processing. ICP-OES, GS-MS, Milk compliment analyzers were used to measure milk trace element contents,fatty acid and conventional ingredients of 30 Jinchuan multi-vertebrate Yaks and 30 Maiwa Yaks at lactation period. The results showed that Jinchuan yak milk’s non-fat milk solids, protein, density, lactose were higher than Maiwa milk (P<0.05). The trace element of the two kinds of milk had no significant difference. The fatty acid C18:0, C18:2 were higher than Maiwa yak milk(P<0.05), while C18:1 had significant difference(P< 0.01). Some quality of Jinchuan yak milk is better than Maiwa’s.
