Concentrates
high energy low fiber feed
highly digestible
mostly for monogastrics
carbonaceous concentrates
low in protein
EX) cereal grains, molasses
nitrogenous concentrates
high in protein
EX) soybean meal, cottonseed meal
Roughages
low energy high fiber
less digestible than concentrates
best for ruminate animals
Corbonaceous roughages
low protein
EX) grass hay, stover, mature cereal grain silage
Nitrogenous roughages
high protein
EX) legume hay and silage, immature grass hay, growing pasture and silage
water
cheapest most abundant nutrient
causes quicker death than lacking any other nutrient
water sources
drinking
ingested in or on feed
metabolic - derived from breakdown of nutrients
water function
transport nutrients and excretions
chemical reactions and solvent properties
temp regulation
maintain shape of body cells
lube and cushion joints and organs
Protein
composed of amino acids - 22 amino acids
, Protein structure
amino acids --> peptide-->polypeptide-->protein
Essential Amino Acids
Animal must have - must be through diet
Essential Amino Acids
Methionine
Arginine
Threonine
Tryptophan
Histidine
Isoleucine
Leucine
Lysine
Valine
Phenylalanine
Nonessential Amino Acids
needed but made in the body
Protein Analysis
determine Nitrogen content then multiply by 6.25
1. Crude protein
2. Digestable Protein
Nonprotein Nitrogen
urea, biuret
Protein Function
4cal/g
basic structure unit of animal
body metabolism - enzymes, hormones, immune antibodies
Energy source
Photosynthesis
produces carbs
Monosaccharides
one sugar molecule
glucose
fructose
galactose
mannose
Disaccharides
