Proteins
  • Chains of Amino Acids
    • Essential amino acids
      • Must be provide through the diet
      • Ruminants add in microbial growth

Essential & Nonessential Amino Acids
protein1
Protein
  • Swine
    • Very important
    • Lysine a limiting amino acid in swine diets
  • Ruminants
    • Important, but…..

Fermentation microbes can make them

protein2
Protein
  • Sources
    • Vary in absorption rate
      • Egg proteins the highest 90%
      • Animal sources 60-80%
      • Plants 40-60%
protein3
Protein
  • largest and most costly part of the ration
  • composed of amino acids
protein4
Protein
  • enzymes are composed of protein
  • protein can be used to supply energy
protein5
Protein
  • some animals need more protein than others
  • young animals
  • lactating (milk producing) animals
protein6
Protein
  • twenty three types of amino acids
  • ten essential
  • thirteen nonessential
protein7
Protein
  • crude protein content
  • total amount of protein in a feed
  • calculated by multiplying nitrogen content percentage times 6.25
protein8
Protein
  • digestible protein
  • the protein in a feed that can be digested and used by the animal
  • usually about 50-80% of crude protein
protein9
Protein
  • protein sources
  • animal
  • slaughterhouse by products
  • dried fish meal
protein10
Protein
  • plant
  • superior to animal sources
  • cottonseed meal
  • soybean meal, linseed meal
  • peanut meal, corn meal
protein11
Protein
  • balancing rations is based on the amino acid content
