1. Poultry Improvement Contest Protein

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

3. 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.

4. 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.
