Answer 3

Rumen

Question 4

The three compartment inactive and undeveloped of Calf’s stomach

Question 5

Ruminat livestock includes :

Answer 5

Cattle
Sheep
Goat

Question 6

Ruminant have a unique digestive system that allows them to better use energy from fibrous plant material than other herbivores

Question 7

Ruminat digestive system to ferment feedstuff and provide precursors for energy for the animal use.

Question 8

Function is to buffer pH level in the reticulum and rumen

Answer 8

Saliva

Question 9

Swallowed again and passed into the reticulum

Answer 9

Cud

Question 10

Largest stomach compartment

Answer 10

Rumen

Question 11

Are considered one organ because they have similar functions and are separated only by a small muscular fold tissue.
Reffered to as

Answer 11

Reticulorumen

Question 12

Home of population of microorganism (microbe “rumen bugs”) that includes bacteria, protozoa and fungi.

Answer 12

Reticulorumen

Question 13

Ferment and break down plant cell walls into their carbohydrates fractions and produce volatile fatty acids. Used for energy

Answer 13

Acetate (used for synthesis)
Propionate (used for glucose synthesis)
Butyrate (carbohydrates)

Question 14

Called the “honeycomb”

Answer 14

Reticulum

Question 15

Main function is to collect smaller digesta particles and move them into the omasum, while larger particles remain in the rumen for further digestion

Answer 15

Reticulum

Question 16

Also traps and collect heavey/dense objects the animal consumes

Answer 16

Reticulum

Question 17

Sometimes reffered to as the “hardware stomach”

Answer 17

Reticulum

Question 18

Sometimes called “paunch”

Answer 18

Rumen

Question 19

Rumen pH ranges from

Answer 19

6.5 to 6.8

Question 20

It is called the “many plies” or the “butcher’s Bible” refers to the many folds or leaves that resemble pages of a book.

Answer 20

Omasum

Question 21

It is called the “many plies” or the “butcher’s Bible” refers to the many folds or leaves that resemble pages of a book.

Answer 21

Omason

Question 22

Water absorption occurs in omasum

Question 23

“True stomach” of the ruminant.
It is the compartment that is most similar to a stomach in a nonruminant

Answer 23

Abomasum

Question 24

Abomasum produces hydrochloric acid and digestive enzymes such as pepsin (break down protein)

Receives digestive enzymes secreted from the pancreas , such as pancreatic lipase (break down fats)

Question 25

Secreted from the first section of the small intestine, duodenum, to aid in digestion.

Answer 25

Bile from gall bladder

Question 26

Active absorption occurs throughout the ‘ including rumen by pass protein absorption.

Answer 26

Small intestine

Question 27

The intestinal wall contains numerous “finger-like” projection called

Answer 27

Villi

Question 28

Is a large blind punch at the beginning of the large intestine.
It serves little function in ruminant

Answer 28

Cecum

Question 29

Is the site of most of the water absorption in the large intestine

Answer 29

Colon

Question 30

Immature ruminants such as young growing claves from 2-3 months of age are nonruminant

Question 31

In these young animals is formed by muscular folds of reticulum.
It shunts milk directly to the omasum and then abomasum, by passing reticulorumen

Answer 31

Reticular groove (esophageal groove)

Question 32

In a calf at birth what is the largest compartment of the stomach, making up more than 50 percent of that total stomach are.

Answer 32

Abomasum

Question 33

Developing good understanding of ruminant digestive anatomy and function can help livestock producers better plan appropriate nutritional programs and
Proper manage ruminat animals in various production systems

Question 34

Fermentation of the plant materials occurs in the

Answer 34

Rumen
