Status of Genetic Resources and Their Conservation and Utilization of Yak in Qinghai Province
The yak is one of the few major livestock breeds that can make full use of the forage resources of the Tibetan plateau for livestock production.It is a unique and precious genetic resource and an important means of production and livelihood for local herders,and the protection and utilization of its unique genetic resource diversity has a significant impact on the development of the economic and ecological balance of the Qinghai pastoral area.However,for a long time,little research has been done to improve yak breeding and crossbreeding in China,and not enough attention has been paid to it,resulting in a low overall level of yak production development,and even to some extent,a serious degradation of yak breeds,a continuous decline in individual production performance making the commercial rate low and the economic efficiency poor,so it is urgent to protect Qinghai yak germplasm re-sources.This paper describes the ecological environment of Qinghai yak and its superior characteristics and traits,introduces the current situation of yak germplasm conservation and utilization,and discusses the problems and countermeasures of yak breed conservation and utilization in order to provide theoretical support for the conserva-tion,utilization,research and production of yak resources.
