There are four PARTS to a ruminant
stomach NOT four stomachs
Rumen
Reticulum
Omasum
Abomasum
These are animals like cows, sheep,
and goats
Part One: The Rumen
• The feed is mixed around and when full
the animal forces the food back up and
chews it more
• This is called chewing cud
• Then the food is swallowed again and
the process starts over until the solids
are completely liquid
Part Two: The Reticulum
• There is no division between the rumen
and reticulum
• There are millions of bacteria breaking
things down here
Part Three: The Omasum
• This is a strong muscle but the exact
purpose is not known
• It is thought to grind things down more
Part Four: The Abomasum
• Called the “true stomach”
• The feed is mixed with gastric juice here
• The digestion here is carried on the
same as non-ruminant animals
Non-ruminant Stomach
• This is a normal 1 part stomach
• The food gets here and is broken up by
gastric juices
• Then it moves on to the small intestine
• These are animals like pigs, horses,
and dogs
Absorbing Feed
• The most absorption of nutrients takes
place in the small intestine only a small
amount takes place in the large
intestine
• The food is not broken down enough to
be absorbed through the earlier stages
in digestion

They need them to:
To reproduce
To grow
To live
Carbs & Fats
• These are things such as Hay, silage,
grains, molasses, and oils
• These are all absorbed during digestion
in the small intestine
• They are then broken down and used
for energy
Proteins
• They are considered the “building
blocks of life” because they go into the
creation of tissues that provide growth
• Necessary for muscle growth
Vitamins & Minerals
• Fat and water soluble
• Provide structural support
• Minerals are a source of some vitamins
Water
• Helps body, and cells maintain shape
• Maintains body temp
• Aids in digestion and moving food
through digestive tract
• Helps produce milk
• Flushes toxins and waste material
