  • 1. Animal Nutrition
    By: Brad and Jon
  • 2. Nutrition
    Nutrition- the process in which animals consume and utilize food.
    Feed efficiency= “rate of gain”
    The feed must have proper nutrients to support life processes of an animal.
    Diet must provide balanced ration.
  • 3. Feed effifiency
    Livestock producers- watch nutrition to decrease the # of days until market.
    Companion Animal Owners- limit animal feed in order to maintain animal health and contentment.
    Balanced Ration- the total amount of feed an animal gets in 24 hour period.
  • 4. 6 Essential Nutrients
    Needed to insure life
    Provide lots of energy
    Without them, problems can occur body mass, lactation, maturity time
  • 5. water
    Dissolves nutrients that animals eat, controls body temp., carries nutrients throughout the body.
    Notable facts: younger animals have 80% water and 40%-80% maturity animals.
    You give them water and should be fresh and clean
  • 6. Carbohydrates
    Provides energy, which powers muscles in the animal. Produces body heat and provide fat if not burned.
    Made of starches, sugars, cellulose
    Simple carbs- easily digested in nitrogen free extract.
    Complex- fibers more difficult to digest 75% carbs
    Can be obtained from cane molasses, ground corn, wheat middlings and dehydrated alfalfa meal.
  • 7. Fats
    Provide body with heat and energy
    Easily digestable
    Contains 1-5% in feeds
    Come from animal and vegetable sources
    Brewer’s dried grains, corn gluten meal, and distillers dried grains.
  • 8. Proteins
    Supply material to build body tissues
    Essential for fetal development
    Also essential for tissue growth
    Made of amino acids
    Ligaments, muscles, organs, skin and horns are all made partially of protein
    It can be obtained by soybean oil meal, linseed meal, cottonseed meal and meat and bone meal.
  • 9. Minerals
    Minerals aid in growth
    Also aid in the body processes
    Inorganic materials
    Macro minerals are needed in large amounts
    Micro minerals are needed in small amounts
    Minerals are usually mixed in with feeds as supplements.
  • 10. Vitamins
    Provide material for growth of bones, teeth and tissue.
    Regulate chemical process
    Aid in muscular activity
    Help repair tissue
    Two groups of vitamins:
    Trace and Major
    Are thrown in to feeds as supplements
  • 11. 5 Different Diets
  • 12. Maintenance
    Maintaining life of the animal
    Consist of Protein, minerals, vitamins, and water, certain fatty acids.
    All of these animals need it
  • 13. Growth
    Nutrients given for growth after maintenance. Increases size of muscles and organs
    Consist of high protein and vitamins/minerals
    Use for weight gaining animals
  • 14. Reproduction
    Nutrients given so an animal can reproduce effetely and to breeding animals
    Diet consist of high in protein and extra minerals/vitamins
    Use for mother, pigs, ex……..
  • 15. Lactation
    To produce milk as a product
    Diet consist of vitamins/minerals, protein and fats/calcium/ phosphorus
    Use for cows, swine, sheep, goats
  • 16. Work
    When animals are used to do work
    Diets consist of extra carbs, fats and extra protein, extra salt
    Use for horses, mules
  • 17. Pearson’s Square Steps to Use
    1. Draw a square
    2.Label feeds and crude protein percentages on the left corners and feeds on right corner.
    3.Subtract the smaller number from the larger along the diagonal lines
    4.Divide the parts of feed by the total parts to % of each feed in the ratio
    5.Use total lbs need to determine lbs of each feed need.
    6.Check to make sure protein needs are met.
  • 18. Chicken Experiment
    We preformed a feed experiment with chickens.
    We feed chickens 4 different types of feed to see which one had the highest rate of gain.
    The feed tags of each feed were analyzed and we made a hypothesis on which feed we believe would have the most rate of gain.
    The feed with the most protein had the highest rate of gain.
