What is "abomasum"?

The abomasum is the true stomach of ruminant animals, such as cows, sheep, and goats. It is the fourth chamber of their complex stomach system. Unlike the preceding chambers, the abomasum functions similarly to the stomach of monogastric animals, secreting gastric juices and enzymes to break down food further. It plays a crucial role in the digestion and absorption of nutrients from the ingested plant material. The abomasum is responsible for the breakdown of proteins, fats, and carbohydrates, allowing for their subsequent absorption into the bloodstream. In this way, the abomasum contributes to the overall digestion and nourishment of ruminant animals.
