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