Protein
large chains of amino acids, highest concentration of nutrients in animals
Insoluble Protein Locations
feathers, hair, wool, hooves
Soluble Proteins
plasma globins
Amino Acid Structure
amino and carboxy group on carbon skeleton
Amino Acid
building block of proteins
Protein Properties Source
amino acid sequence and links to other compounds
Iron and Protein
hemoglobin
Phosphorus and Protein
casein
Carbohydrates and Protein
glucoproteins
Lipids and Protein
lipoproteins
Protein Synthesis Control
DNA controls order of amino acids
Amino Acid Supplies
originates from diet or from digestive processes
Number of Amino Acids
20 amino acids in plant and animal proteins
Plant Amino Acid Production
can be fully synthesized from inorganic nitrogen
Essential Amino Acid
non dispensable, animals cannot produce in adequate amounts
Nonessential Amino Acid
dispensable, animals can produce adequate amounts
Likely Limiting Amino Acids
lysine, methionine, tryptophan
Cereal Grain Amino Acids
very low in most, may need to supplement
First Limiting Amino Acid
the amino acid that is present in the least amount, halts protein synthesis
Amino Acid Supplements
from protein feed sources or straight amino acids, economic considerations
Ruminant Amino Acid Requirements
different dietary requirements, microbes are utilized as microbial protein
Microbe Protein Production
microbes can reproduce with a nitrogen source, no protein required
Animal Protein
higher quality, milk and fish products
Plant Protein
oilseed meal, soybean meal
Highest Quality Protein
animal protein, sources are more closely matched to animal requirements
Protein Digestibility
75-80% digestible
Stomach Protein Digestion Enzymes
pepsin, trypsin, peptidase
Soybean Trypsin Inhibitor
can affect protein utilization by blocking trypsin
Pepsin Digestive Function
protein to polypeptides
Tryptsin Digestive Function
polypeptide to peptide
Peptidase Digestive Function
peptide to amino acids
Biological Value
portion of amino acids retained by an animal
Biological Value Factors
efficiency of digestive processes, feed efficiency, requirement for amino acids
Amino Acid Absorption
absorbed in anterior small intestine, affects biological value
Protein Efficiency Ratio
grams or body weight gain per unit protein
Net Protein Value
efficiency of growth between testing protein and a protein free diet
Net Protein Value Factor
comparing body nitrogen uptake
Net Protein Value Calculation
digestibility of protein multiplied by biological value
Blending Diets
helps obtain amino acid balance, associative effect from content differences
Excess Amino Acids
absorbed amino acids can be utilized to energy
Protein Biological Value Compared
animal > bacterial > plant
Amino Acid Requirements
highest in young growing animals, decreases as growth decreases, lowest during maintenance
Increased Amino Acid Requirement Condition
pregnancy, lactation, egg production
Dietary Protein Defeciency
one or more limiting amino acids, inadequate dietary protein levels
Signs of Protein Deficiency
poor growth rate, reduced nitrogen retention, poor utilization and lowered consumption of feed, lowered birth weights, higher infant mortality, reduced production, infertility
Blood Urea Nitrogen
can be used to assess protein status
Lysine Deficiency Sign
white barring of primary flight feathers in black turkeys
Excess Protein
no adverse effects short term
Excess Protein Issue
when giving non protein nitrogen to monogastrics
