yak

Only because yak is living in remote area and oxherd, with low knowledge,  has less communication with outside world , the yak is less heard and popular as sheep and milk cow.

只因牦牛栖息偏远地区，养畜牦牛的牧民又甚少与外界接触，识水平都普遍低下，以致牦牛的经济价值不及羊和乳牛般广。

A preliminary study has been made on what measures of technology of animal husbandry should be adopted in order to increase the economic profit of yak production in yak purebreeding.

但耗牛繁殖率和生产性能低,成熟晚,单位面积草原饲牧耗牛的经济效益不高。

The jokes get yaks.

那笑话引发笑。
