• Protein

2
Proteins

• Proteins are organic compounds made from amino
  acids.
• They contain carbon, hydrogen, oxygen, nitrogen,
  and some sulfur.

Protein Comes From

• Plants
• Protein is found in small amounts in the germ of
  grain kernels.
• Protein supplements include soybeans, soybean
  meal, cottonseed meal, canola, and legumes.
• Animals
• Protein supplements include fish meal, meat and
  bone meal, dried milk products, blood mea and
  tankage.

Why Are Proteins Needed?

• Proteins are needed for new tissue growth and
  replacement of old or damaged tissue due to
  injury or disease.
• Help to form the greater part of muscles,
  internal organs, skin, hair, wool, feathers,
  hoofs, and horns.

5
Protein Requirements

• The two (2) most important factors to remember
  when feeding protein
• Amount of protein.
• Quality of protein.
• These two factors interact with each other (we
  can feed less of a high quality protein and vice
  versa).

6
Essential Amino Acids

• Many Amino Acids are considered essential for
  poultry because they can not be made in
  sufficient amounts for body functions.
• Must be provided in the ration.
• Arginine, Histidine, Isoleucine, Leucine, Lysine,
  Methionine, Phenylananine, Threonine, Tryptophan,
  Valine, Alanine, Aspartic Acied, Glycine, and
  Serine.

7
Nonessential Amino Acids

• Nonessential Amino Acids in poultry rations.
• They are considered nonessential because they can
  be synthesized in the body of animals from other
  amino acids.
• They do not need to be provided in the ration.
• Citrulline, cysteine, cystine, glumaic acid,
  Hyroyglutaic acid, hydroxpyproline, Norleucine,
  Proline, and Tyrosine.

8
Too Much Protein

• Any protein in excess of the amounts needed for
  growth and tissue repair is burned and used to
  supply energy.
• This is a costly way to provide energy.
  Carbohydrates are a cheaper energy source.
• TIP-Feeding too high of a protein ration may
  cause fatty liver syndrome.
