1.To study further the biological characteristics and genetic diversities of wild yakand domestic yak and their hybrid, the living weight gain and body size of wild yak(WY, 1 year old) and Datong yak (DI, 1 years old) from Datong County ofQinhai Province , and Tianzhu black yak (TZ, 1 years old) from Tianzhu Countyof Gansu Province were measured and some blood physiological parameters werealso determined The experiments were divided into three periods in a year.
为深入研究野、家牦牛及其杂交种的生物学特性和遗传多样性，作者对青海大通牛场野牦牛（1岁）、大通牦牛（1～2岁）及甘肃天祝县天祝黑牦牛（1～2岁）的生长及部分血液生理指标、做了为期一年（分三期）的跟踪测定。
2.People use them as beasts of burden, weave their hair into fabrics, drink yak milk or churn it to butter, eat yak meat, and gather the yak droppings as an excellent fuel.
人们用牦牛驮运重物、用它们的毛编织衣服、喝牦牛奶、用牦牛奶制奶油、吃牦牛肉，并把牦牛粪当作上好的燃料。
3.Study on the FSHβ Gene of Maiwa Yak and Jiulong Yak by PCR-SSCP
麦洼牦牛和九龙牦牛FSHβ基因的PCR-SSCP分析
4.There was a polymorphic site in the exon 1 of MSTN in Piedmontese Cattle, Qinchuan Cattle, Tianzhu White Yak, but the gene frequency was very low in Qinchuan Cattle, Tianzhu White Yak. To verify the relationship between the genotypes of MSTN and the phenotypes, we should enlarge the sample size for further analysis.
研究发现胚胎移植肉牛只有皮埃蒙特和天祝白牦牛、秦川牛在MSTN基因的第三外显子存在变异，但在天祝白牦牛、秦川牛中基因频率较低，需扩大样本深入研究。
5.Comparative Analysis on Karyotype of Domestic Yak and Yak with Wild Blood
家牦牛与不同野血牦牛染色体组型的比较分析
6.The allele β~(135Asn) is the characteristic of Chinese yak after residue blasting. It is suggested that the β135 Asn of this allele could reduce the oxygen affinity of yak hemoglobin.
等位基因1β35A sn是中国牦牛特有的一个等位基因,推测该等位基因编码的第135位氨基酸天冬酰胺,可能会降低牦牛血红蛋白的氧亲和力。
7.Usage: 1.Medicate the liquor with the yak penes, Chinese caterpillar fungus and the fruit of Chinese wolfberry. 2.Better to stew the sliced yak penes with Chinese angelica, Dangshen and Chinese wolfberry.
食用方法:1,与虫草,枸杞等泡制药酒服用.2,用热油炸后温水浸泡后切片与当归、党参、枸杞、炖汤食用效果更佳.
8.There are kettles for yak butter tea and bolts of colorful fabric for traditional Tibetan robes and clothing.
有盛酥油茶的茶壶以及用来做传统西藏长袍和衣服的卷卷花布。
9.Se pills used in Yaks may also reduce the Yak death by 10. 73%~14. 73% ,and the sub-clinic incidence of Se-deficit disease will be completely controlled. Milk production cna be raised by 23. 7%.
口服Se丸可有效地防治牛缺硒病,硒丸用于耗牛可减少死亡10.73％～14.73％,100％预防亚临床发病,提高产奶量23.7％。
