Ruminants

The complex stomach Livestock

Ruminant:

A multi compartment stomach animal (ex. cattle, sheep, goats).

The cow has four stomachs and undergoes a special digestive process to break down the tough and coarse food it eats. When the cow first eats, it chews the food just enough to swallow it. ... The cud then goes to the third and fourth stomachs, the omasum and abomasum, where it is fully digested.

Reticulum :

• Honey Comb Texture

• Menudo

• Second stage feed stuff visits after mechanical digestion in the mouth.

• Controls contractions that moves feedstuff around

Reticulum

Pretty obvious why this is called the honey comb

Multiple Choice

The Reticulum is known as the

• ant pile

• bears nest

• honeycomb

• bee hive

Multiple Select

• omasum

Multiple Choice

What dish do we Hispanics eat that comes from a part of the digestive tract?

Rumen

Sheep, cattle, goats, deer, giraffes and llamas are ruminant animals. This means that they have a four-chambered stomach.

 

The rumen serves as a large fermentation vat in which bacteria and other microorganisms reside. These microbes are capable of breaking down feedstuffs that the cow cannot. As part of this process, they produce a number of by-products, such as volatile fatty acids (VFAs), which the animal absorbs and uses as energy.

Rumen

The rumen is the largest of stomach compartments in the ruminants digestive tract.

Microbes aid the break down the feedstuff in the rumen before the bulk is pushed out into the next chamber.

Probably the most important chamber.
