Feeds and Feed Label
Ms. Wellborn
Objectives:
 Identify sources of nutrients and classes of feed.
 Identify vitamins, minerals, and feed additives.
A Little Review
 Can anyone tell me what we talked about
yesterday?
 Can anyone remember and name the 6 essential
nutrients?
 Can someone tell me what palatability means?
 Can someone tell me the two- types of vitamins
there are?
Basic Nutrients and Their
Function
 Regulatory
 Energy
 Water
 Protein
 Minerals
 Fats
 Proteins
 Carbohydrates
 Vitamins
 Structural
 Minerals
 Proteins
 Fats
Water
 Cheapest and most abundant nutrient
 Most important
 Functions:




Regulates body temp.
Nutrient/waste transportation
Aids in digestion/absorption
Regulate ionic concentrations
Carbohydrates
 Occurance:
 Plants 60-80%


Cell content- sugar and starch
Cell wall- cellulose and hemicellulose
 Different classifications
 Can anyone name some classifications of carbohydrates?
 Functions:




Energy
Heat
Building Blocks
Fat Disposition
Fats (Lipids)
 Contain 2.25x more than carbohydrates
 Functions:




Dietary energy supply
Source of heat, insulation, and protection for the body
Sources of essential fatty acids
Serve as a carrier for absorption of fat- soluble vitamins
 Classification:
 Simple
 Compound
 Derived
Protein
 Principal component of organs and soft structures in the
body
 Digestible protein- portion of crude protein which the
animal digests
 Crude protein- composed of true protein and any other
nitrogenous product
 Functions:
 Structural- collagen, elastin, blood proteins
 Body metabolism- enzymes, hormones, immune antibodies
 Distinct functions- defense mechanism, hooves, cell
membranes
Minerals

Natural Sources



Forage plants
Grains
Macro
Minerals normally preset at greater
levels in the body or needed in
relatively large amounts in the
diet
Ca, P, Na, Cl, Mg, K, S

Micro

Normally present at love levels
in the body or needed in very
small amounts in the diet
 Co, Cu, F, I, Fe, Mn, Mo, Se,
Zn

Functions:






Structural and skeletal
development
Function in protein synthesis
Oxygen transport
Fluid balance
Regulating acid-base balance
Activation of many enzyme
systems
Vitamins
 Fat soluble- A, D, E, K
 Water soluble- thiamine,
riboflavin, niacin,
pyridoxine, pantothenic
acid, biotin, choline, folic
acid, B12
 Functions:
 Regulators of metabolism
 Growth and maintenance
of life
 Antibody synthesis
 Requirements increase
with age
Now
 Take a minute to look at the feeds in front of you
 Fill out the worksheet to the best of your ability.
 What are the feed additives added to the feeds in
front of you?
 What do you think those additives are used for?
Objectives
 Identify sources of nutrients and classes of feed.
 What sources of nutrients and classes of feed did we
look at today?
 Identify vitamins, minerals, and feed additives.
 What kind of vitamins, minerals, and additives did we
find in the feeds we looked at?
