What are the digestive physiological characteristics of donkeys? Read this article to understand

Digestive physiological characteristics of donkeys: Donkeys have hard, well-developed teeth and flexible upper and lower lips, suitable for chewing coarse and hard feed. Donkeys have well-developed salivary glands; every 1 kg of forage can be softened and digested by 4 times its amount in saliva. The donkey's stomach is small, only equivalent to one-fifteenth that of a cow of the same size. The cardiac sphincter of the donkey's stomach is well-developed, while the vomiting nerve is underdeveloped, so it is not easy to feed feed that ferments and produces gas, to avoid gastric dilation. Chyme stays in the stomach for a short time; when the chyme in the donkey's stomach reaches two-thirds, as feeding continues, the stomach contents are continuously discharged into the intestine. The donkey's cecum is relatively large; food remains in the cecum for 18 to 24 hours, accounting for more than one-third of the time food remains in the digestive tract.
