The document discusses the digestive system of ruminants. It begins by stating the objectives are to describe the four parts of the ruminant stomach and examples of ruminant animals. Ruminants like cattle, sheep, and goats can digest roughages because they have a four-chambered stomach containing microorganisms that break down cellulose. The four stomach chambers are the rumen, reticulum, omasum, and abomasum. The rumen ferments cellulose with microbes and gases are released when ruminants eructate. Nutrients are somewhat absorbed and feed is reduced in size before moving to the next chambers.

TEMA: DIGESTIBILITY IN RUMINANTS.

NOMBTRE: MAGALY LESCANO NIVEL: SEGUNDO A

DIGESTIBILITY IN RUMINANTS. Ruminant Digestive System. Objectives: Know the four parts of the ruminant stomach. Know examples of animals that have a rumen. Be able to describe the function of all four of the parts of the ruminant stomach. What are some animals that have Rumens? Cattle Sheep Goats

Deer

Elk

What do all of these animals have in common? They all live off of grass, and other rough ages.

Why cant we live off of the same things cows eat?

How can a Ruminant digest these things? Through the process of rumination. Eating rapidly, regurgitating and masticating their feed. (Chewing their cud) With specialized structures in their stomach. Ruminants have microorganisms living in them that break down cellulose for them and make those nutrients absorbable. What are these four structures?

Rumen: Large fermentation vat. Microorganisms break down cellulose. Creates lost of gases (methane) Ruminants have to be able to eructate (belch) Some nutrients are absorbed. Roughages are reduced in size.

Rumen Feed Storage:

Rumen (Punch):

Reticulum:

Collects objects that shouldnt be in the digestive system. Nails Screws Baling wire Magnets are placed into many dairy animals reticulums.

Reticulum (Hardware Stomach or Tripe):

Omasum (manyplies): Works to remove water from the food. Absorbs fatty acids.

Abomasum (True Stomach): Glandular Stomach (like yours) Secretes digestive juices. Breaks down food stuff further for absorption. Absorbs some nutrients.

Order that food moves. Rumen Reticulum Omasum Abomasum
