Animal Nutrition
What is animal nutrition?

The dietary needs of domesticated and
captive wild animals
Why is animal nutrition important?

Animals need proper nutrition to support their
body requirements:
–
–
–
–
–
Growth
Maintenance
Work
Reproduction
Lactation
How are nutritional requirements
determined?

Digestive System
–

Feeding Type
–

Ruminant or Non-Ruminant
Carnivore, Omnivore or Herbivore
Body Requirements
How are nutritional requirements
met?

By feeding a balanced diet
What is a balanced diet?

A feeding program that:
–
–
–
Stimulates natural
feeding behaviors
Meets all nutritional
requirements
Is practical and
economical
How are natural feeding behaviors
stimulated?

Feeding diets that allow the
animal to obtain their food in a
similar manner to that in the wild

How are nutritional requirements
met in the diet?

Providing a diet that consists of the 6 basic
nutrients in quantities appropriate for each
specific animal species
What are the 6 basic nutrients?






Carbohydrates
Fats and Oils
Proteins
Vitamins
Minerals
Water
What are carbohydrates?


Nutrients made up of sugars, starches &
cellulose
Provide energy
–

Largest source of energy in a diet
Source
–
–
–
Cereal grains (corn, wheat and oats)
Roughage (alfalfa hay, grasses and plants)
Sugars (Molasses to improve taste & reduce dust)
Corn
What are fats & oils?


Nutrients made up of triglycerides and fatty
acids
Provide energy
–
2.25 times the energy as carbohydrates



Extra carbs are stores as fat
Carry fat soluble vitamins
Source
–
–
Grain & protein concentrates (corn & soybean oil)
Natural feed ingredients (meat, fish, nuts & eggs)
Soybean Oil
What are proteins?


Nutrients made up of amino acids
Provide materials for growth
–

Body tissues (muscles, skin & hair)
Source
–
–
Plant (soybean, cottonseed & alfalfa meal)
Animal (meat & fish meal, dried milk)
Meat
What are vitamins?


Organic compounds, containing carbon, needed
in small amounts
Provide materials for body regulation
–
–

Water soluble (B-complex & C)
Fat soluble (A, D, E & K)
Source
–
–
Pre-mix (powder added to feed, best way to provide)
Natural feed ingredients (fruits & vegetables)
Vitamin C
What are minerals?


Inorganic compounds, containing NO carbon,
needed in small amounts
Provide materials for growth and regulation
–
–

Bones, teeth & tissues (calcium & phosphorus)
Chemical homeostasis (iron, folic acid & copper)
Source
–
–
–
Pre-mix (powder) or mineral block (separate from feed)
Natural feed ingredients (meat, milk, green vegetables)
Nature (soil & rocks)
Calcium
What is water?


The most important nutrient, essential for the
survival of all animals
Provides:
–
–

Hydration of body
Transport system for nutrients (dissolves & carries)
Source
–
Supplied separately from diet

From a clean well or plumbing
H2O


Carbohydrates
–
–
Provide energy
Sources

Cereal Grains
–
Corn (most popular)
– Oats and Wheat

Roughages
–

Alfalfa Hay (high energy/fiber)
Sugars
–
Molasses (increases palatability *taste* and reduces dust)


Fats and Oils
–
Provide energy

–
–
2.25x more than carbohydrates
Carry fat soluble vitamins
Sources

Grain and protein concentrates
–

Vegetable oil
Natural sources
–
Meats, nuts and dairy products
Nutrient Review

Proteins
–
–
Provide amino acids for growth and development
Sources


–
Meat, Bone and Fish meal
– Dried milk

Plant
–
Soybean and cottonseed meal
*The word meal is almost always after the protein
