1, tripe is the stomach of cattle, also called Bai Ye and belly tip; It is one of the internal organs of cattle. Niubaiye can be used as food, generally used for hot pot, fried food and other purposes. 2. Cows are ruminants. Different from other domestic animals, the biggest feature is that it has four stomachs, namely rumen, reticular stomach (honeycomb stomach), flap stomach (louver stomach, commonly known as bovine louver) and abomasum. The first three stomachs have no gastric glands and do not secrete gastric juice, which are collectively called forestomachs. The fourth stomach has gastric glands, which can secrete digestive juice, similar to the stomachs of pigs and people, so it is also called true stomach. The roughage eaten by cattle is mainly decomposed into absorbable substances through rumen microbial fermentation.
