| Abstract: | The nutrient components of ninety samples of yak milk collected from Tianzhu and Maqu of Gansu Province and Tianjun of Qinghai Province were determined and analyzed.The results showed that the fat of yak milk were significant different among three regions,while no significant differences were found in TS,Snf,lactose,density,FPD and acid.With the increasing of the altitude,the fat and protein of the yak milk from three regions were both increased obviously,but the other indexes showed no obvious changes.In addition,birthrank had no obvious influence on yak milk nutrient components. |
| Keywords: | yak milk nutrient components altitude birthrank |
