What is the real stomach of a cow called?

The digestive system of cattle is multi-chambered and contains several different stomach chambers, each of which is responsible for a specific digestive function. The true stomach of a cow is called the rumen, one of the largest and most important stomach chambers in the cow's digestive system.

The rumen system of cattle includes four rumens: rumen, reticulum, omasum and abomasum, also known as rumen pouch (rumen), rumen reticulum (reticulum), rumen portal (omasum) and rumen original (abomasum). Together, these rumens form the unique multi-chambered gastric digestive system of cattle.

1. Rumen:

  • Rumen 1 is the true stomach of the cow, also known as the first gastric chamber. It is a fermentation tank with a large volume and is the largest rumen chamber, occupying most of the space in the entire rumen system.

  • In the rumen, it is conducive to the growth and fermentation of microorganisms, which can help break down cellulose and other complex carbohydrates and convert them into easily digestible substances.

  • This fermentation tank is the most important part of the cow's digestive system. Through the microbial fermentation here, the cow can effectively digest cellulose and other plant fibers and extract energy.

2. Reticulum:

  • The reticulum is located in front of the rumen, connected to the rumen, and has a grid-like shape, so it is also called the ruminal reticulum.

  • The rumen mesh helps the cow ruminate, promoting further refinement and digestion of food.

3. Omasum:

  • The omasum is located between the rumen and the reticulum and looks like a string of beads, so it is also called ruminal beads.

  • Rumen beads mainly play the role of filtration and absorption, which can help cattle fully absorb water and trace elements and reduce residue in other rumens.

4. Abomasum:

  • The abomasum is located at the end of the omasum and is similar to the human stomach.

  • The abomasum is mainly the part of the gastric glands that secretes gastric juice and helps digest proteins and other nutrients.

The multi-chamber gastric digestive system of cattle enables it to effectively digest plant fiber and extract nutrients. This digestive organ structure helps cattle make full use of plant fiber and adapt to a diet with plants as the main food source. The rumen system of cattle is the core of cattle nutritional digestion, ensuring efficient energy utilization during the cattle's feeding, rumination, and digestion processes.
