Objectives

Learn the 7 nutrients
animals need
Cost

What is major cost in a livestock
operations?
Breeding stock
 Equipment
 Labor
 Medication
 Feed

 Greatest
expense is Feed
Nutrition

Nutrients

Found in feed materials
that are necessary for
proper body functioning.
Roughages and Concentrates

Concentrates
Feed High In Crude (Total) Protein
 75% protein is digestible


Roughages
Feeds High in Fiber low in CP
 60% of Protein
 More than 18% fiber

Feeds Types


Dry Grain: Crushed
(crimped) corn
Silage: Fresh cut
roughages that are
sealed to keep moisture


These types of feeds are
supplemented with
nutrients to optimize heath
Pre-mix: mixture of
nutrients supplemented to
livestock feed
Nutrients
Carbohydrates

Main energy nutrients made
up of sugars, starches, and
cellulose

Found in the largest quantities
of livestock feed

Source: in Cereal Grains


Corn, rye, wheat, barley,
and sorghum
Corn is commonly used in
the US
Fats and Oils


2.25 times the energy
value of Carbs.
Carry Fat soluble
Vitamins


Extra Carbs. are stored as
fat
Source: Come in grains
and protein concentrates
Vitamins



Trace organic
compounds
Help regulate body
functions and are
designates as letters
Sources: Adds to
most feed as a premix
Proteins


Organic Compounds
made up of amino acids
Supply material to build
body tissues


Mussels, skin, hair
Sources: soybean meal,
cottonseed meal, blood
meal, dried milk, urea
Minerals



Inorganic Material in
small amounts
Provides growth of
bones, teeth and body
tissues and regulate
many chemical body
process
Sources: In most feed,
pre-mixes, mineral blocks
Water

Makes up 40-80% of
the animals body


Most important nutrient
Dissolves other nutrients
and caries them
throughout the body
