1. What are the two types of Digestive systems? Name an example of each.
a. Monogastric –human, dogs, pigs
b. Ruminant- Cow, sheep, goats
2. Define digestion.
a. The process of breaking down food into smaller particles
3. What is the process of digestion? (Start to end)
a. Mouth, esophagus, stomach, duodenum, small intestine, cecum, colon, rectum, anus
4. List each organ in the monogastric digestive system and tell the function of each. (Notes Pages Chart. If you
have the chart from your notes just attach to study guide)
5. Chemical Reactions in the Monogastric Digestive Process
Organ
Function of
Enzyme/Acid
Mouth
Stomach
Duodenum
Pancreas
Breaks down
starch
Example:
Gastric Acid
Maltase
Amylase
Pepsin
Sucrase
Lipase
Lipase
Lactase
Trypsin
Amylase
Rennin
Peptidase
Chymotrypsin
6. What is the difference in the saliva of a ruminant compared to a Monogastric animal?
a. The saliva in a monogastric has amylase to start breaking down food, the saliva in a ruminant does not
have amylase so it doesn’t start breaking down food in the mouth.
7. What are the four compartments in the ruminant stomach? Describe each.
a. Rumen, reticulum, omasum, abomasum
8. What path do ground concentrates, light grains, and forages take through the ruminant stomach?
a.
9. Can Monogastric animals digest forages?
a. no
10. List the 6 basic nutrients then describe each.
a. Water, vitamins, proteins, carbohydrates, minerals, fats
11. What are the 4 life stages? Describe each.
a. Maintenance- maintaining weight (no weight gain or loss), nutrient requirements low
b. Gestation- female is pregnant, nutrient requirements are higher, 3rd trimester needs most nutrients
c. Lactation- female is producing milk
d. Growth and Development – growing larger and stronger, developing tissues and muscles, require
additional nutrients
12. In which trimester of gestation will the female need the most nutrients?
a. 3rd
13. In which life stage will an animal need less nutrients?
a. maintenance
14. List sources of information on nutritional requirements.
a. Texrtbooks, computer, National Research Council (NRC), extension agents, feed companies
15. Identify sources of nutrients.
Water
Pond, well
Protein
Grains, legumes, amino acids in animal tissues
Carbohydrates
Sugars, starches, and fibers in grain and forages
Fats
Fatty acids in animal tissues, fats, and grains
Vitamins
Grass, sun-cured hay, and commercial feeds
Minerals
Plant and animal tissue and commercial feeds
16. Know how to balance a ration. Look at worksheets.
