Protein Swine Ruminants 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 90% Animal sources 60-80% Plants 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
