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
• Water
• Minerals
• Proteins
• Vitamins
• Structural
• Minerals
• Proteins
• Fats

• Energy
• Protein
• Fats
• Carbohydrates

5
Water

• Cheapest and most abundant nutrient
• Most important
• Functions
• Regulates body temp.
• Nutrient/waste transportation
• Aids in digestion/absorption
• Regulate ionic concentrations

6
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

7
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

8
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

9
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

10
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

11
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?

12
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?
