Regions are cardia, fundic, body, pyloric

24
Q

Describe anatomy of ilium cecum and large intestine

A

Ilium in small intestine

Cecum first region of large intestine

25
Q

Name two mucosal membrane adaptations and their benefit.

A

Q

Name two categories of starch

A

RAC simple, complex

29
Q

Describe what happens when unadapted animals are fed large amounts of cereal grains.

What are some errors in growth trials?

A

Variations in feed

Genetic differences

36
Q

How are external indicators used in growth trials?

A

Nitrogen markers

37
Q

Define canula? Benefit?

A

A surgically inserted tube. To test digestion in different areas.

38
Q

What can cause variations in digestibility in the same species?

A

Genetics

39
Q

Three groups of rumen bacteria?
