Figure 17. Ruminant stomach

When food enters the stomach, it first goes to

rumen. The rumen serves to temporarily hold food. in it Deer, giraffes and rhinos

occurs processes of decay and fermentation by cellulase black is an animal foliage-

enzymes produced by bacteria and protozoa. Bacteria eaters. Leaf can be obtained

that play a role in the process of fermentation of from a tree or bushes. Zebra

bacteria of the genus Cyptophaga and Bacterium, while a grass eater. Most mammals

its protozoa are the genus Flagellates, such as herbivores have teeth straight-

Cypromonas subtitis. tipped front to bite, and teeth

Next, the food coming from the rumen will go to cheeks, molars and molars a

Sarcoplasmic. In this part, the food is formed into flat-top front to chew with

coarse lumps called bolus. While resting, animals perfect.

ruminants often have their mouths chewing. This is

done because the bolus of the reticulum is expelled back

towards the oral cavity. From oral cavity, food re-enters

the omasum and is passed on to the abomasum (the real

stomach). Inside the abomasum, food ingested just like

in the human stomach, namely chemically. Come on, Watch!

After ingestion in the abomasum, food goes to the

small intestine. Inside the small intestine, the juices of

food are absorbed by blood vessels to be circulated

throughout the body. The rest of the food digestion is

passed on to the rectum which is then removed through

the anus.

The digestive process of ruminants is different

from other breeding animals such as horses, cheliques,

or guinea pigs. Difference lies in the process of chewing https://unej.id/RuminantDigestiveTract

food that is not carried out twice. In addition, the

process of fermentation of its cellulose takes place in Click link or watch a video of the

ruminant digestive tract
the cecum (appendix), not in the rumen. Meanwhile,

some rodents such as rabbits have cellulose-
decomposing bacteria in the colon, not in the stomach.
