Detailed explanation-1: -Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum .

Detailed explanation-2: -Animals that have stomachs with four special compartments are called ‘ruminant’ animals. Their complex digestive systems allow them to process partially-chewed grass and other vegetation, absorb nutrients and produce energy.

Detailed explanation-3: -Most ruminants have a four-chambered stomach and two-toed feet. The upper incisors are reduced or sometimes absent. Camels and chevrotains, however, have a three-chambered stomach and are often referred to as pseudoruminants. Ruminants eat quickly.

Detailed explanation-4: -The ruminant stomach has 4 compartments: 1) rumen, 2) reticulum, 3) omasum, and 4) abomasum (Van Soest, 1994). Pregastric fermentation and breakdown of feeds occurs in the rumen, reticulum, and omasum, whereas the abomasum is the true stomach and is similar in structure and function to the non-ruminant stomach.

Detailed explanation-5: -Sheep, cattle, goats, deer, giraffes and llamas are ruminant animals. This means that they have a four-chambered stomach. The four chambers of the ruminant stomach are the reticulum, rumen, omasum and abomasum. The rumen serves as a large fermentation vat in which bacteria and other microorganisms reside.
