The flashcards below were created by user alyssau12 on FreezingBlue Flashcards. What would you like to do?


  1. What is needed for an efficient energy transfer?
    appropriate energy to protein ratio
  2. What happens if there isn't enough protein?
    affects metabolism, enzymes and growth
  3. What happens if there's too much protein?
    interrupts the pathway
  4. What differentiates proteins?
    type and length of amino acid chains
  5. Why is quality of proteins important?
    higher quality proteins have all essential amino acids
  6. What dictates the amino acid?
    R group
  7. What does the liver do for amino acids?
    breaks amino acids into specific proteins
  8. What are the limiting amino acids?
    • lysine
    • threonine
    • methionine
  9. Types of proteins, one example and function:
    • enzymes--amylase--digestion
    • transport--hemoglobin--transport oxygen in blood
    • storage--milk--milk
    • contractile--actin, myosin--muscle movement
    • protection--antibodies--fight infection
    • hormones--insulin--carbohydrate metabolism
    • structural--elastin--ligaments
    • toxins--snake venom--snake venom
  10. What has higher levels of protein? legumes or grasses
    legumes
  11. How can you determine CP?
    Nitrogen x 6.25
  12. CP needed depends on what?
    • feed intake
    • digestibility of protein
    • classification/horse's need
    • quality of protein
  13. feed intake is based on:
    dry matter (feed without water content)
  14. If a feed is high in fiber...
    it will by-pass the small intestine and go straight to the cecum
  15. When is the protein value in a plant higher?
    • when it is young
    • decreases with age
  16. fiber is higher when...
    a plant is older
  17. CP requirements:
    range for a horse at maintenance based on amount of activity
  18. What are BCAAs?
    • branch chain amino acids
    • drive carbohydrate metabolism
