PROTEIN TERSUSUN DARI ASAM AMINO H R C NH 2 COOH

Proteins • Chains of Amino Acids – Essential amino acids • Must be provide through the diet • Ruminants add in microbial growth – Non-essential amino acids • Required but the body can synthesize them

Protein • Swine – Very important – Lysine a limiting amino acid in swine diets • Ruminants – Important, but…. . Fermentation microbes can make them

Protein • Sources – Vary in absorption rate • Egg proteins the highest • Animal sources • Plants 90% 60 -80% 40 -60%

Protein • largest and most costly part of the ration • composed of amino acids

Protein • enzymes are composed of protein • protein can be used to supply energy

Protein • some animals need more protein than others • young animals • lactating (milk producing) animals

Protein • twenty three types of amino acids • ten essential • thirteen nonessential

Protein • crude protein content • total amount of protein in a feed • calculated by multiplying nitrogen content percentage times 6. 25

Protein • digestible protein • the protein in a feed that can be digested and used by the animal • usually about 50 -80% of crude protein

Protein • protein sources • animal • slaughterhouse by products • dried fish meal

Protein • plant • superior to animal sources • cottonseed meal • soybean meal, linseed meal • peanut meal, corn meal

Protein • balancing rations is based on the amino acid content
