Study on the Mineral Content of Yak Milk and Cattle-Yak Milk in Qinghai Province
摘要
Abstract
[Objective]To study the difference and correlation of mineral content between yak milk and Cattle-Yak milk under grazing conditions.[Method]From July to August 2019,in Guinan County of Qinghai Province,selected parity,weight,age,lactation performance,no supplementary feeding healthy yak and Cattle-Yak 13 each,and collected milk samples,a total of 78 samples were obtained,and determined the mineral content of milk through the flame atomic absorption meter.[Results](1)In four kinds of constant mineral(K,Ca,Na,Mg)of yak milk and Cattle-Yak milk,except Na(P>0.05),the other three minerals are significantly different(P<0.05),including K content in Cattle-Yak milk is significantly higher than that of yak milk,but Ca and Mg of yak milk is significantly higher than that of Cattle-Yak milk;5 kinds of trace minerals(Fe,Cu,Zn,Co,Mn)content are obvious differences.Cu and Co of Cattle-Yak milk is significantly higher than yak milk,while Fe,Zn and Mn of yak milk are significantly higher than Cattle-Yak milk.(2)Most of the minerals in the milk show a correlation.[Conclusion]The above results show that yak milk has 5 kinds of mineral content higher than Cattle-Yak milk,and Cattle-Yak milk has 3 kinds of minerals is higher than yak milk,indicating that yak milk is better than Cattle-Yak milk in terms of mineral.关键词
