Digestive Tract Basics
What are the three main livestock digestive systems
monogastric, ruminant, and hind-gut fermentor
Cattle, sheep, and goats
What is a single stomach animal
The first place food is stored in poultry
What is the crop
Name the type of digestive system that has a single, simple stomach.
What is a monogastric digestive system?
The primary function of the digestive system
Break down food and absorb nutrients
In order, what are the four compartments of the ruminant stomach
The rumen, reticulum, omasum, and abomasum
Major livestock species with a monogastric digestive system
What are pigs
The true stomach of poultry
What is the proventriculus
Which chamber of a ruminant’s stomach is primarily responsible for absorbing nutrients and water?
What is the omasum?
The main function of the liver
What is create and synthesize bile
The ruminant stomach compartment where bloat occurs
What is the rumen
The muscular organ that continually contracts to churn food particles to make sure they are mixed with all of the enzymes for chemical digestion to occur
What is the stomach
The organ in poultry that mechanically breaks down food into smaller particles
What is the gizzard
Horses and rabbits are examples of which type of digestive system
What is a hindgut fermenter
The three components of small intestine
What is the duodenum, ileum, and jejunum
The ruminant stomach compartment most similar to the monogastric stomach
What is the abomasum
The function of the large intestine
What is absorbing water and some nutrients
The organ in which waste is excreted from poultry
What is the cloaca
Which part of a horse’s digestive system is the primary site of microbial fermentation of fibrous plant material?
What is the cecum?
The process of chewing
Masticiation
The structure in young ruminants that allows milk to bypass the rumen straight to the abomasum
What is the esophageal groove
The process used to move food down the esophagus
What is peristalsis
Explain how the avian digestive system compensates for the lack of teeth in grinding food, including the two organs involved.
What is the crop stores food temporarily and the gizzard grinds it mechanically?
Name the two main parts of a horse’s large intestine that are involved in fermentation and water absorption.
What are the cecum and colon?
