Abstract:Yak，as a characteristic livestock species with remarkable plateau adaptability，is widely distributed in Qinghai，Xizang，and other places in China and some areas in neighboring countries，and its industrial chain covers breeding，farming，processing，marketing，and other links，with high economic value. However，the overall development of the yak industry is lagging behind，and the processing of yak is still in the primary stage，with a large amount of by-products not fully utilized. This paper summarized the current situation of the yak industry，main nutrients，processed products，and comprehensive utilization of by-products and looked forward to the prospect of comprehensive processing and utilization in the yak industry，aiming to provide a theoretical basis for the deep processing and sustainable development in the yak industry.
