Digestive System of Ruminants Animals
The digestive system in Ruminant animals is discussed in our Digestion in Ruminants and Non-Ruminants homework help online. Ruminants animals have a special kind of digestive system. These animals have a four-chambered stomach.
- Mouth: The mouth lacks enzymes and both chews and softens the food
- Esophagus: It directs the movement of food from mouth to rumen
- Rumen: It is a part that differentiates the ruminant animals from others. It has a big sac-like structure, which is present between the small intestine and esophagus. Here, food is stored temporarily and thereafter it returns to the mouth. After chewing, the food passes down to reticulum.
- Reticulum: The bacteria ferment the food. This separates the finely ground materials from coarse materials and keeps the hardwood pieces.
- Omasum: It has leaf-like components having rough surfaces. It can absorb water. The food becomes ground finely.
- Abomasum: Here the protein breakdown takes place using enzymes. The proteins pass on to a small intestine and here the remaining digestion happens just like humans.
Special features in ruminant animals
- Presence of rumen
- A four-chambered stomach
- The saliva does not have enzymes
- Digestion, as well as absorption, happens mainly in the stomach
- It can digest cellulose
Digestive Animals in Non-Ruminant Animals
These animals are monogastric and have a simple digestive system, however, they cannot digest a huge amount of fiber. Some of the examples are dogs, cats, pigs, and even humans. However, rabbits are horses are different.
The digestive system of these animals has the features of ruminants as well as monogastric animals. The gastrointestinal tract of non-ruminant animals is similar to that of monogastric. The digestion that is available to monogastric animals takes place in the small intestine and stomach. If the feed is more fibrous, which majorly happens is passed via the small intestine to the colon and caecum. Here the digestive process takes place similar to what happens in the rumen.
The bacteria that inhabit the colon and caecum is identical to what is found in rumen. The bacteria fermented is also similar to ruminant animals. There is the absorption of bacterial fermentation including amino acids, fatty acids, minerals, and B-vitamins released from the plants.
This way the animals can receive a large portion of its needs from the fibrous sources, digesting what it gets and eliminating the remaining quickly from the tract. Animals having high nutrients needs, need a diet with a greater proportion of supplements. This is explained in our help for assignment on Digestion in Ruminants and Non-Ruminants.
