Abstract:The yak breeding is an important part of the economic income of herding households in Sujitan Township, Menyuan County. With the continuous development of local animal husbandry, the stock of yak breeding has been increasing year by year. However, the increase of breeding quantity leads to the natural grassland pasture can no longer meet the demand of cattle, while the unscientific nutrition regulation, improper ratio of breeding males and females and diseases cause the increase of Empty?Breasted yaks, which seriously restrict the healthy development of yak breeding industry in the whole township. In order to understand the number of Empty?Breasted yaks in Sujitan Township, find the causes of Empty?Breasted yaks and provide suggestions to farmers. In this survey, 50 yak farmers were randomly selected within the five villages of the township to carry out the survey and analysis work on the number of Empty?Breasted yaks.
