Abstract:
As a critical component of global agriculture,the dairy industry is essential for the food security and economic development.In China,the dairy sector in plateau regions plays an important role in addressing the nutritional needs of residents,boosting farmers' incomes,and fostering re-gional economic growth.However,the harsh high-altitude conditions,such as low oxygen,low at-mospheric pressure,and severe climate,pose significant challenges to the health and survival of dairy cows.This article summarizes the changes in physiological characteristics,metabolic perform-ance,production performance,and health status of dairy under high altitude areas,providing in-sights for the identification of adaptive traits in dairy to plateau.Also,the genetic and epigenetic mechanisms behind these phenotypic adaptations are discussed,and future directions and strategies for enhancing adaptability of dairy of dairy n plateau regions are outlined,thereby guiding re-searchers in adaptation evolution and breeding of dairy cattle.
