The stomach of cattle consists of four chambers, namely, rumen, honeycomb stomach, heavy stomach and wrinkled stomach, which are described as follows:

1. Rumen: The rumen of an adult cow can have a volume of up to 151 liters, and is capable of storing 136 kilograms of contents. The function of the rumen is mainly to temporarily store feed cattle feeding a large amount of feed stored in the rumen, resting large feed particles will be regurgitated into the mouth, slowly chewed, chewed feed quickly through the rumen, to provide space for eating feed again.

2, mesh stomach: the volume of the mesh stomach of cattle accounts for about 5% of the volume of the four stomachs, is the smallest of the four stomach chambers; the main function of the mesh stomach as a sieve, with the feed eaten into the heavy objects, such as nails and wire, are present in it.

3, heavy valve stomach: accounted for the total volume of the stomach?7-8%, slightly flattened on both sides of the spherical, located in the right quarter of the ribs; it is generally believed that its main function is to absorb the water within the feed and extrusion of the feed grinding.

4, wrinkled stomach: about 7-8% of the total volume of the stomach, a long curved sac with a thick anterior end and a thin posterior end; its function is the same as that of the stomach of monogastric animals, secreting digestive juices and making the food wet.

Expanded Information:

< p>The mucosa of the rumen, reticulum, and flap stomach (antrum) is lined with a complex flat epithelium; the mucosa of the crumple stomach (true stomach) is lined with a single columnar epithelium. The flap stomach is to the right of the junction of the omentum and rumen, approximately opposite the lower half of the 7-11 (12) rib interspace, with the horizontal line of the shoulder joint passing through the midline of the flap stomach. The flap stomach of the sheep was the smallest of the four stomachs, ovoid in shape, and located in the lower half of the 8th to 10th ribs.

The reticulum stomach is located on the median sagittal plane of the quarter ribs, about opposite the 6th to 8th ribs; the rumen is a large oval sac slightly longer in front and back and slightly flattened on the left and right, occupying almost the entire left side of the abdominal cavity.
