Title: Poultry Improvement Contest


1
Poultry Improvement Contest
  • Fats, Minerals, and Vitamins

2
Review
  • Nutrition
  • Six Essential Nutrients
  • Water
  • Fats
  • Carbohydrates
  • Proteins
  • Minerals
  • Vitamins

3
Fats
  • Fats also contain carbon, hydrogen, and oxygen
    but in different ratios than carbohydrates.
  • Fats contain about 2 1/4 times the energy value
    of carbohydrates

4
Why Feed Fat?
  • Aids in absorption of certain vitamins.
  • Increases the palatability of the ration.
  • Decreases dustiness and dryness of the ration.
  • Increases the production energy of the ration.
  • Found as a component in every cell in the body.

5
  • Fats are composed of fatty acids and glycerol.
  • Fats are either saturated or unsaturated.
  • They differ in chemical make up.

6
Essential Fatty Acids
  • Fatty acids are required by chickens
  • Without them they grow poorly, and can get fatty
    livers.
  • Large amounts of fishy or rancid flavors are
    undesirable to the chicken and will flavor the
    meat.

7
Minerals
  • Minerals are inorganic(not made from carbon).
  • Exist primarily in the form of salts and ash.
  • Essential for bone and eggshell formation and
    regulatory processes in the body.

8
Essential Minerals
  • Poultry require calcium, phosphorus, magnesium,
    manganese, sodium, potassium, iron, copper, zinc,
    sulfur, fluorine, chlorine, iodine, selenium, and
    molybdenum.
  • Macrominerals such as calcium, phosphorus, and
    sodium are required in the largest amounts and
    must be included as additives in the ration.

9
Calcium
  • Required for
  • Bone and eggshell formation.
  • Blood clotting.
  • Muscular actions.
  • Lack of calcium
  • Causes rickets which results in soft rubbery
    bones and thin shelled eggs.
  • Limestone is provided to laying hens in the form
    of grade limestone and oyster or clam shells.

10
Phosphorus
  • Important mineral needed by the bone.
  • Its need goes hand in hand with calcium.
  • Sources include
  • Dicalcium phosphate
  • Bone meal
  • Defluorinated rock

11
Sodium and Potassium
  • Essential in maintaining electrolyte balance in
    body.
  • Poultry deficient in potassium have
  • Reduced growth
  • Increase in kidney and urinary problems
  • Poultry deficient in sodium have
  • Poor growth
  • A nervous condition that may bring on cannibalism
  • Poor utilization

12
  • Potassium usually is in the ration.
  • Sodium is usually added in small amounts as
    common table salt.
  • Magnesium
  • Is important to the tissues and body fluids.

13
Vitamins
  • Complex organic structures essential in minute
    amounts for
  • Growth
  • Reproduction
  • Overall health
  • The purpose of vitamins is body regulation rather
    than development and structure.
