Protein in Animal Feeding
Organic compounds made up of amino acids
Contain: carbon, hydrogen, oxygen, and nitrogen. Some may contain sulphur, phosphorus, and iron
Supply materials to build body tissue (ligaments, hair, hooves, skin, organs, and muscle are partially formed by protein)
Protein in animal production
Is the largest and most costly part of the ration
Is limited available As essential nutrients Is most deficient nutrient Excess intake, economically and
biologically not efficient
Crude and True protein True protein : Nitrogen compound
only as protein. Crude protein : All nitrogen
compounds including also Non Protein Nitrogen (NPN) in addition to protein.
Crude protein Total nitrogen x 6.25 Proteins on average contain 16%
nitrogen
Protein in Non- Ruminant Animals
Non-ruminant animals can not synthesize the essential amino acids fast enough to meet the animals needs therefore those essential amino acids must be provided in the ration
Need to feed balanced ration with the right balance of essential amino acids
If grains are combined in the correct combination they will provide a balanced ration.
Soybean meal is most commonly used
Ruminant animals generally synthesize the essential amino acids by the rumen at a rate to meet the needs of the animal
Can be met by feeding proteins of vegetable sources
Also by feeding urea (synthetic nitrogen source made from air, water and carbon)
Urea is mixed with the ration to to provide nitrogen for making amino acids in the ruminants body
