What are the 4 chambers of a ruminant's stomach?
Cattle have ruminant stomachs -- stomach with four separate compartments. The compartments are called the rumen, the reticulum, the omasum and the abomasum. Each compartment has its own specialized duty in the digestive process.
The cow is a ruminant with four stomachs:
- omasum; and.
- Turns out “goats have four stomachs” is sloppy shorthand for “goats have one very large stomach split into four compartments”: the rumen, the reticulum, the omasum, and the abomasum.
- Giraffes are ruminants (like cows, sheep, and deer). This means that they have more than one stomach. In fact, giraffes have four stomachs, and the extra stomachs assisting with digesting food.
- Of this group, sheep are more of a grazer, while goats and deer are browsers. The primary difference between ruminants and simple-stomach animals (called monogastrics), such as people, dogs, and pigs is the presence of a four-compartment stomach. The four parts are the rumen, reticulum, omasum, and abomasum.
The cow's digestive tract consists of the mouth, esophagus, a complex four-compartment stomach, small intestine and large intestine (figure 1). The stomach includes the rumen or paunch, reticulum or "honeycomb," the omasum or "manyplies," and the abomasum or "true stomach."
- There are about 150 different domestic and wild ruminant species including cows, goats, deer, buffalo, bison, giraffe, moose and elk. Camelids (llamas and alpacas) are called "pseudo-ruminants" because they have a three-compartment stomach instead of four like ruminants. Horses are not ruminants.
- The pig has a digestive system which is classified as monogastric or nonruminant. Humans also have this type of digestive system. They have one stomach (mono = one, gastric = stomach). The monogastric differs from that of a polygastric or ruminant digestive system found in cattle and sheep.
- They have only one stomach! It simply has four compartiments. Animals with this specialization are called ruminants. Quoting Wikipedia: "Ruminating mammals include cattle, goats, sheep, giraffes, yaks, deer, antelope and some macropods."
