HUMAN NUTRITION

Detailed explanation-1: -The omasum is a globe-shaped structure containing leaves of tissue (like pages in a book). It absorbs water and other substances from digestive contents. Feed material (ingesta) between the leaves will be drier than ingesta found in the other compartments.

Detailed explanation-2: -Water absorption occurs in the omasum. Cattle have a highly developed, large omasum. Interior lining of the omasum, revealing the “many piles” tissue folds in an 8-week-old calf. The abomasum is the “true stomach” of a ruminant.

Detailed explanation-3: -The function of the omasum is incompletely understood; however, the omasum plays an important role in the transport of appropriately sized feed particles from the reticulorumen to the abomasum, esophageal groove closure, fermentation of ingesta, and absorption of water, volatile fatty acids, and minerals.

Detailed explanation-4: -The omasum is where food particles that are small enough get transferred into the abomasum for enzymatic digestion. In ruminants with a more sophisticated omasum, the large surface area allows it to play a key role in the absorption of water, electrolytes, volatile fatty acids, minerals, and the fermentation of food.

Detailed explanation-5: -The main function of the omasum is to represent an arrangement for continuance of the fermentation in all species. 2. The pH of omasal contents of sheep and cattle is near neutral and the rate of fermentation equals the rate in the rumen.
