The real stomach of cattle is wrinkled stomach, cattle **** have four stomachs, the first three stomachs are esophageal variants, namely rumen (grass belly), web stomach (honeycomb stomach, hemp belly), flap stomach (heavy flap stomach, lily pads), and the last one is the real stomach (wrinkled stomach).

Cattle are ruminants, different from other livestock, the biggest feature is that there are four stomachs. The first three stomachs have no gastric glands inside and do not secrete gastric juices, collectively known as the antrum. The fourth stomach has gastric glands that secrete digestive juices and is similar to the stomachs of pigs and humans, so it is also called the true stomach. The roughage fed to the cattle is mainly fermented and decomposed by the microorganisms in the rumen into substances that can be absorbed and utilized.

Functions of the four stomachs of the cow:

1, rumen

The rumen is the first stomach of ruminants, and it is the unique digestive organ of ruminants. Unique digestive organs, the rumen is the strongest known ability to degrade fibrous material natural fermenter.

The rumen epithelium can effectively absorb Na+, K+, Cl- and other ions, and the absorption of volatile fatty acids can be up to 75%, and the absorption rate is in the order of butyric acid > propionic acid > acetic acid, which plays an important role in regulating the internal environment of the rumen.

2. The mesh stomach

is located in the front part of the rumen, in fact, these two stomachs are not completely separated, so the feed particles can move freely between the two. The main function of the mesh stomach is like a sieve, with the feed eaten into the heavy objects, such as nails and wire, are present in it, the mesh stomach will play the role of filtration.

3, valve stomach

The third stomach of ruminants. It is located in the right side of the anterior part of the abdominal cavity. The mucosal surface forms many different sizes of leaf petals, no digestive glands. Its main function in the retention of the rough part of the food, continue to be finely ground, and transport the thinner part of the wrinkled stomach, while absorbing a lot of water and acid.

4, wrinkled stomach

Commonly known as the true stomach, the function is similar to the stomach of monogastric animals, different from the former stomach, the stomach with digestive glands, can secrete digestive enzymes, with a real sense of digestion, so it is known as the true stomach, but also known as the "glandular stomach".
