Ruminant Digestion
  • Relationships Between Organisms
what is a ruminant
What is a ruminant?
  • Specialized digestive system capable of digesting cellulose.
  • Has a stomach with 4 distinct compartments
  • Cattle, sheep, goats, deer & elk.
compartment capacity
Compartment Capacity
  • Reticulum 5% of capacity
  • Rumen 80% of capacity
  • Omasum 7% of capacity
  • Abomasum 8% of capacity
reticulum
Reticulum
  • Hardware stomach
  • Holds foreign materials like nails

Omasum

* Muscular section that squeezes out excess water from food products before passing along in the digestive process.

rumen
Rumen
  • Largest compartment
  • Storage area
  • Millions of bacteria and protozoa live here and break down cellulose into digestible protein and carbohydrates
abomasum
Abomasum
  • True stomach
  • Site of chemical digestion
  • Digestive juices containing enzymes break down food products to be absorbed by the small intestine
types of relationships between organisms
Types of Relationships between organisms
  • Mutualism each helps the other.
  • Commensalism one benefits, the other does not.
  • Parasitism one depend on the other for essential food factor, usually harmful to the host.
  • Phoresis the host carries the “symbiont”
commensalism

vocabulary review
Vocabulary Review

Monogastric A digestive system with one stomach compartment

Polygastric A digestive system capable of breaking down cellulose into digestible protein and carbohydrates. The stomach is divided into compartments each with a specialized function.

Ruminant An animal with a polygastric digestive system.

Rumination Part of the process of digestion in a polygastric system where a bolus is regurgitated, re- chewed and swallowed.

Vocabulary Review

Abomasum Site of chemical digestion in a polygastric digestive system.

Reticulum “hardware stomach” holding area for foreign materials in a polygastric system.

Rumen Largest compartment of the polygastric system, serves as a storage area.

Omasum Muscular portion of the polygastric system that squeezes excess water from digested food products.

vocabulary review16
Vocabulary Review

Mastication The act of chewing where salivary enzymes are added to food products.

Bacterial digestion The bacterial and protozoa action in the rumen of a polygastric digestive system that breaks down cellulose into digestible carbohydrate and protein products and synthesizes B vitamins.

Bolus Partially chewed food held in the reticulum that is regurgitated, chewed completely and re- swallowed.

vocabulary review17
Vocabulary Review

Parasitism Relationship between two organisms where one depends on the other for some essential food factor, often to the detriment of the host.

Mutualism Relationship between two organisms where one benefits and the other doesn’t.

Commensalism Relationship between two organisms where one benefits and the other doesn’t’.

Phoresis Relationship between two organisms where the host transport the sybiont.
