Yaks living on the Qinghai-Tibetan Plateau for a long time have evolved a series of mechanisms to adapt to the unique geographical environment and climate characteristics of the plateau. Compared with other ruminants, yaks have higher energy utilization and metabolic efficiency. This paper presents possible mechanisms responsible for the efficient energy utilization, absorption and metabolism resulting from the unique evolutionary process of yaks. It is hoped that the information discussed in this review will give a better insight into the uniqueness and superiority of yaks in regards to energy metabolism and utilization compared with cattle and open new avenues for the targeted regulation of energy utilization pathways of other ruminants.
长期生活在青藏高原的牦牛进化出了一系列机制，以适应高原独特的地理环境和气候特征。与其他反刍动物相比，牦牛具有更高的能量利用和代谢效率。本文阐述了牦牛独特进化过程所导致的高效能量利用、吸收和代谢的可能机制。希望本综述中讨论的信息能让人们更好地了解牦牛在能量代谢和利用方面相对于牛的独特性和优越性，并为有针对性地调控其他反刍动物的能量利用途径开辟新的道路。
