Ten Essential Amino Acids Phenylalanine Valine Threonine Tryptophan Isoleucine Methionine Histidine Arginine Leucine Lysine Ten Non-Essential Amino Acids Protein and Amino Acids in Swine PIH-5 Swine do not have a protein requirement Requirement is to : 1. 1. Specific amounts of the ten individual essential amino acids. 2. 2. Non-specific N to synthesize the non-essential amino acids. Other Concepts 1. If any one of the essential amino acids is deficient - it limits tissue growth. Protein Synthesis "all or none" FIGURE 1 Ideal Protein Balance of Amino Acids A.A. % of Lysine Lysine 100 Threonine 65 Methionine & Cystine 55 Tryptophan 18 Isoleucine 60 Leucine 110 Histidine 33 Phenylalanine & Tyrosine 120 Valine 75 Essential Amino Acids 45 Non-Essential Amino Acids 55 2. Amino acid requirements are dependant upon: a. Energy content of the feed must maintain constant protein: calorie ratio actually lysine: calorie ratio.

b. Increase with protein content of > diet. c. Genetic potential to growth. d. Sex: boars > -gilts > -barrows e. Objective maximum carcass leanness > F/G > liveweight gain. f. Interrelationships between the amino acids. f.1. Cystine can provide up to 50% sulfur amino acids methionine and cystine. f.2. Tyrosine can provide at least 50% of total of phenylalanine and tyrosine. 3. Pigs utilize L-isomers only with exception: D-methionine 100% available D-typtophan 60% - 70% available 4. Diet with good amino acid balance even though below the recommended level in protein will not hurt feed intake. A deficiency of amino acids or imbalance excess will hurt feed intake and growth. 5. High protein feedstuffs must provide the correct ratio of amino acids limited in the energy feed grains; corn, milo, wheat, etc. i.e. grower with corn protein source must be as a percent or total protein, lysine 6.25%, . 66% tryptophan, 2.41% threonine. High Protein Feedstuffs % of Protein Feedstuff CP Lysine Tryp Thr Soybean Meal 44 6.55 1.25 4.25 Soybean Meal 48 6.55 1.30 4.12 Blood meal 85 9.53 1.29 4.82 Meat & Bone Meal 50 5.20 .56* 3.00 Fish Meal 60 7.67 .87 4.45 Skim Milk 32 7.50 1.38 5.00 Whey, whole 12 5.66 1.25 8.58 Fish meal, skim milk, whey - high biological value feed.
