1, rumen
Rumen is an important digestive organ of cattle. When cattle feed and ruminate, the weakly alkaline saliva secreted flows into rumen, which can neutralize the fatty acids produced by carbohydrate fermentation.
At the same time, rumen epithelial tissue can also absorb Na+, K+ plasma and most volatile fatty acids, which plays a good regulatory role in rumen environment.
2, net stomach
Reticular stomach is located at the front end of rumen. Because its endothelium has honeycomb tissue, it is also called honeycomb stomach. Reticular stomach mainly plays a filtering role, that is, it screens out what cattle eat like a sieve. For example, there may be some indigestible heavy objects in the feed, such as nails and stones. And retained in the feed after being screened by net stomach.
3. Stomach flap
The valve stomach, also known as the double valve stomach, is connected with the reticular stomach in front and then with the abomasum. Its main function is to process the rough part of ground food, transport the thinner part to the abomasum, and at the same time absorb a lot of water and acid.
4, abomasum
Its function is the same as that of monogastric animals. It has digestive glands and can secrete digestive enzymes. It is the real digestive organ in the four stomachs of cattle, so it is also called abomasum.
