Proteins.
The abomasum, often referred to as the "true stomach" in ruminants, produces several key enzymes, including pepsin, rennin (or chymosin), gastric lipase, and lysozyme. Pepsin is responsible for protein digestion, while rennin aids in curdling milk in young animals. Gastric lipase helps in the digestion of fats, and lysozyme has antibacterial properties, assisting in the maintenance of gut health. These enzymes play crucial roles in the digestive process of ruminants.
A deer's digestive system is adapted for processing plant material, particularly fibrous vegetation. They are ruminants, meaning they have a four-chambered stomach that includes the rumen, reticulum, omasum, and abomasum. Initially, food is fermented in the rumen and reticulum, where microbes break down cellulose. The partially digested food is then regurgitated as cud, chewed again, and swallowed for further digestion in the omasum and abomasum, where nutrients are absorbed.
Most herbivores have a specialized stomach structure to aid in the digestion of plant material. The number of stomach compartments varies among species: ruminants like cows and sheep have four chambers (rumen, reticulum, omasum, and abomasum), while non-ruminant herbivores like horses have a single-chambered stomach but possess a large cecum for fermentation. Other herbivores, such as rabbits, also have a single stomach but rely on a unique digestive process involving cecotrophy.
Macromolecule digestion typically begins in the mouth with the breakdown of carbohydrates by amylase. Further digestion of macromolecules like proteins and lipids occurs in the stomach and small intestine with the help of various enzymes such as pepsin and pancreatic lipase.
Animals with more than one stomach, such as pigs and cows, are referred to as "polygastric", poly- meaning many and -gastric referring to the stomach.The scientific term is called poly-gastric ("many-stomach), for example cows are ruminants, they have four stomachs (or one stomach with four chambers).
The smallest chamber of the stomach of ruminants is the abomasum. It is often referred to as the "true stomach" and is similar in function to the stomach of non-ruminants, where enzymatic digestion occurs. The abomasum follows the rumen, reticulum, and omasum in the digestive sequence. This chamber plays a crucial role in breaking down feed and absorbing nutrients.
Ruminants have a compartmentalised stomach. There are 4 compartments, the rumen, reticulum, omasum and abomasum. A non ruminant does not have a compartmentalised stomach, the non ruminants stomach has similar fucntions to that of the abomasum in the ruminants
The abomasum is the 'true stomach' of ruminants, such as cows and sheep. It is the only glandular section of their stomach - and is acidic (it is very similar to the simple stomach of monogastrics, such as pigs).
The stomach of ruminants has four compartments: the rumen, reticulum, omasum and abomasum
The abomasum is known as the true stomach of ruminants because it functions similarly to the stomachs of non-ruminant animals, where the digestion of food primarily occurs through enzymatic processes. Unlike the other compartments of the ruminant stomach (rumen, reticulum, and omasum), which primarily serve as fermentation chambers, the abomasum secretes gastric juices that break down proteins and facilitate nutrient absorption. This makes it the site where the digestive process closely resembles that of monogastric animals.
Giraffes, like cows, are ruminants. They have a four-compartment stomach which can pass partially digested food around to aid the digestion of plant matter. The final stomach compartment, called the abomasum, is the closest equivalent to the stomach of a monogastric animal such as a human.
The stomach of ruminants is located in the abdominal cavity, specifically in the left side, near the diaphragm. It is a complex organ divided into four compartments: the rumen, reticulum, omasum, and abomasum. This specialized stomach structure allows ruminants to effectively break down fibrous plant material through fermentation and microbial action before digestion.
The four stomachs (or compartments) are in the following order:The rumenThe reticulumThe omasumThe abomasum
The difference is mainly due to the complexity of carbohydrate digestion. Humans have a single stomach, where ruminants have a multichambered stomach to digest carbs more completely.

Ruminants are a group of mammals that have a specialized stomach structure designed for digesting plant material. They possess a four-chambered stomach, consisting of the rumen, reticulum, omasum, and abomasum, which allows them to efficiently break down fibrous plant matter through fermentation. Additionally, ruminants have a unique ability to regurgitate and re-chew their food, a process known as cud chewing, which aids in digestion. Common examples of ruminants include cows, sheep, goats, and deer.
