[0002] Ruminant refers to the animal that can chew and digest food repeatedly, and its main feature is a special stomach structure, which is usually divided into four parts: rumen, reticulum, omasum and abomasum. Yak is one of the typical ruminants, which can preliminarily ferment and decompose food by entering rumen first, and then regurgitate the food back into the mouth to chew again, which helps to better digest the high-fiber grass food. The process of regurgitation not only improves the digestibility of food, but also helps them better utilize the poor plant resources on the grassland. The digestion method of yak enables them to adapt to the cold and limited grass resources environment on the plateau.
