Question 2

What is animal nutrition?

Answer 2

The study of nutrient requirements, absorption, metabolism, diet formulation and feeding management for animal health.

Question 3

What is nutrient?

Answer 3

Essential for growth, maintenance and repair of an animal’s body.

Question 4

What is digestion?

Answer 4

Process by which food is broken down into smaller components that can be absorbed by the body.

Question 7

What is a requirement?

Answer 7

Amount of nutrition that an animal needs for health and productivity.
-it’s a quantity

Question 8

What is feed?

Answer 8

A single nutrition component or ingredient provided to a animals.

Question 9

What is feed composition?

Answer 9

Nutritional context that animals consume.

Question 10

What is food processing?

Answer 10

Methods used to prepare feed for animals.

Question 11

What are Food Additives?

Answer 11

Substances added to feed to improve nutritional value or prevent disease.

Question 12

What are feeds used for?

Answer 12

To prepare diets for animals to meet requirements.

Question 13

What are the types of digestion and metabolism?

Answer 13

-Ruminant
-Non-ruminant

Question 14

What is a ruminant?

Answer 14

An animal with a four chambered stomach that is able to digest tough plant material.

Question 15

What is a non-ruminant?

Answer 15

An animal with a single chambered stomach that is unable to digest tough plant material.

Question 16

What are nutrient requirements affected by?

Answer 16

-age
-size
-activity
-maintenance

Question 17

True or False: Are there different types of feeds that supply nutrients for different animals?

Answer 17

True

Question 18

What is a feed analysis?

Answer 18

Ability to balance rations to meet requirements depends on establishing the nutrient profile and composition of feed ingredients.
-critical to feeding animals

Question 19

What are the two types of feed analysis?

Answer 19

-Chemical analysis (more accurate)
-Spectroscopic analysis

Question 20

Why are their different feeds for different animals?

Answer 20

-Diet digestibility is influenced by the anatomy of the GI tract.
-different digestive tract structures accommodate and support fiber fermentation

Question 21

What is a way to derive nutrients from fibrous feeds?

Answer 21

Fermentation

Question 22

What are other comparative digestive anatomy?

Answer 22

-Marsupials: carnivores and herbivores
-Omnivores are a little bit of both

Question 23

What does have more gut mean?

Answer 23

Having more gut means more digest and having less gut mean less digestion.

Question 24

What is the difference between ruminants and noon-ruminants when it comes to fiber?

Answer 24

-They digest fiber differently and digest different amounts of fiber.

Question 25

What is Ration Formulation?

Answer 25

-Develop composition of feed and ingredients to supply nutrients to meet requirements
-Establish nutrient requirements
-Depends on animals size, age, production, and physiological state.
-Establish feed ingredients
-use nutrient compositions
-based on intake of the animal
