Ruminant and Pseudo- ruminant
By Rachel Footit and Rebecca Groves
What is a Ruminant animal? It is an animal that has 4 compartments in
their stomach. It contains a rumen, reticulum, omasum,
Abomasum. These are found in cattle, sheep, goats,
and chickens. These help brake down lots of food when
the animals eat.
The Rumen
It’s about 60% of the stomachs. It is also has bacteria and other microbes
that promote fermentation. Food will leave the rumen and get
regurgitated for about 15 minutes and swallowed to the reticulum, then it will be a repeating process for about 2-3 hours.
The Reticulum The 2nd stomach in the system. It looks like a honeycomb. It helps keep the food in the Rumen
mixed with water and saliva. When that is done the mixture can
move on to the other parts of the system.
The Omasum It looks like pages to a book. It absorbs many of the nutrients broken
down in the reticulum and rumen. It removes excess water from food. It reduces the size of food particles
before passing them to the Abomasum for digestion by enzymes
Abomasum It’s last compartment of the stomach
system. It breakdowns the majority of the
chemicals in the food. It also mixes in digestive enzymes The only one having glands that discharge
acids and enzymes for digestion.
What is a Pseudo- Ruminant animal?
They contain 3 compartments in their stomachs.
These animals do not regurgitate or ‘chew the cud’
These animal are still similar to ruminant animals but don’t get the most nutrients out of leafy materials.
Pigs, rabbits , llama, horses, and alpaca are the most known animals to be pseudo-ruminant.
How are the two different? Pseudo- Ruminant animals just have a
large cecum and doesn’t regurgitate their food.
Ruminant animals have a rumen and do regurgitate all their food they intake.
Parts of a Pseudo-Ruminant
There is several parts of the stomach. There is a large Cecum, and a large
intestine.
What is a Cecum?
Helps digest plants in the body. It absorbs water and salts from
undigested food. Has a muscular wall that kneads the
contents to speed up the absorption. This show that the feeds nutrients is
not absorbed as much as an animal with a rumen.
The Large Intestine
It is made up of mostly colons: ascending colon, transverse colon, sigmoid colon.
It actively transport sodium, and absorbs water by osmosis.
It holds an environment where bacteria can grow and reproduce.
It will eliminate all waste, undigested, and unabsorbed material to leave the body.
