different digestive systems
Different Digestive Systems
  • The three different types of digestive systems are:
  • Monogastric
  • Modified Monogastric
  • Ruminant
ruminant
Ruminant
  • A few animals with ruminant digestive systems are sheep, cattle, goats, deer and giraffes.
  • Ruminant animals have four complex stomach structures.
  • The four stomachs are called the rumen, reticulum, omasum and abomasum.
  • Herbivores are usually ruminant animals.
parts of ruminant system
Parts of Ruminant System
  • Mouth- teeth and lips hold food and chew it, saliva moistens food.
  • Esophagus-food travels to stomach.
  • Four Compartments:
  • 1st-Rumen
  • 2nd-Reticulum
  • 3rd-Omasum
  • 4th-Abomasum
1 st compartment rumen
1st Compartment: Rumen
  • Large fermentation vat, where bacteria and protozoa thrive to break down roughages.
  • Rumen is lined with papillae to increase surface area and absorption
rumen
Rumen
  • Contains microorganisms that digest cellulose and can synthesize amino acids as well as B-complex vitamins.

Rumen Sizes in Cattle and Sheep Cow- 40 Gallons

Sheep- 5 Gallons

2 nd compartment reticulum
2nd Compartment- Reticulum
  • Reticulum has a lining with small compartments similar to a honeycomb. Hence its nickname the “honeycomb.”
  • Interacts with the rumen in initiating mixing activity and provides additional storage for fermentation.
  • Capacity:
  • Cow: 2 Gallons
  • Sheep: 2 Quarts
3 rd compartment omasum
3rd Compartment: Omasum
  • Omasum has many folds, often referred to as manyplies.
  • Aids in the grinding action of the food
  • Capacity:
  • Cow: 4 gallons
  • Sheep: 1 quart
4 th compartment abomasum
4th Compartment: Abomasum
  • Abomasum: The true stomach
  • Corresponds with the stomach of monogastric animals.
  • Majority of Digestion takes place.
  • Capacity:
  • Cow 4 Gallons, Sheep 3 quarts
small intestine
Small Intestine
  • Functions in splitting food molecules and in nutrient absorption.
  • Capacity of Ruminant Animals:
  • Cow: 15 Gallons or 130 feet
  • Sheep: 2 Gallons or 80 feet
large intestine
Large Intestine
  • Functions in absorbing water and forms indigestible wastes into solids.
  • Last chance for minor nutrient absorption.
  • Capacity of Ruminant Animals
  • Cow: 10 gallons
  • Sheep: 6 quarts
review of ruminant digestive systems
Review of Ruminant Digestive Systems
  • Animals that have ruminant digestive systems eat forage rapidly and later regurgitate the feed, known as the cud.
  • The regurgitated food is chewed thoroughly, swallowed and then more feed is regurgitated. This process is continued until all the feed is masticated.
how the ruminant system works
How the Ruminant System Works
  • Once the feed has arrived in the rumen, it is mixed with microorganisms, such as bacteria, protozoa and certain fungi. They assist the ruminant animal in utilizing cellulose, and in synthesizing protein from non-protein nitrogen and certain vitamins.
how the ruminant system works14
How the Ruminant System Works
  • Then the feed arrives in the Reticulum that is commonly referred to as the “honeycomb”. Its major function is to work with the rumen in mixing and grinding the feed.
  • Also functions in screening foreign objects from the digestive system.
how the ruminant system works15
How the Ruminant System Works
  • Then the feed arrives in the omasum, or the third compartment referred to as “manyplies.” The omasum assists in removing 60 to 70 percent of the water before the feed enters the abomasum.
how the ruminant system works16
How the Ruminant System Works
  • Once the feed has arrived in the abomasum, or the “true stomach,” digestive juices, which contain enzymes, break down proteins, and add moisture to the feed as it enters the small intestine.
small large intestine in review
Small & Large Intestine in Review
  • From the abomasum, the feed enters the small intestine where nutrients are absorbed in the blood system.
  • From the small intestine, the food passes into the large intestine where the water is removed and the feed is prepared for excretion.
