ANSC 1401 - TTU (Nutrition, Digestion, and Feeds) Latest Update 100% Correct

ANSC 1401 - TTU (Nutrition, Digestion, and Feeds) Latest Update 100% Correct Nutrition science that deals with food and the nutrients it contains that man and animals must have to live and function Study Nutrition because - most costly link to animal production Concentrates high in energy, low in fiber, highly digestible Carbonaceous (Concentrate) low in protein; cereal gains, molasses, carbs turn to energy, examples - corn, milo, wheat, starch, cereal grains Nitrogenous (Concentrate) high in protein; oil meals, fish meal, packing house by-products such as tankage, dairy products, feeding for protein, examples - soy bean mean, cotton seed meal, tankage, dairy products Roughages low in energy, high in fiber, less digestible than concentrates Carbonaceous (Roughages) low in protein; mature grass hay, stover, mature cereal grain silage Nitrogenous (Roughages) high in protein; legume hay and silage, immature grass hay and silage, growing pasture and silage Nutrients chemical substances in either mineral or compound form that are absorbed from the digestive tract into the blood and function in metabolism of the body Water (Nutrient) cheapest and most abundant nutrient, necessary for life, death occurs after loss of 10-14% of ? in the body, minerals regulate body ?, die most quickly without ? Sources of Water 1) drinking 2) ingested - contained in or on feed 3) metabolic - derived from breakdown of nutrients Function of Water 1) transport of nutrients and excretions 2) chemical reactions and solvent properties 3) body temperature regulation (most important) 4) maintenance of shape of body cells 5) lubrication and cushioning of joints and organs Proteins composed of 22 amino acids, building blocks Structure of a Protein amino acids - peptide - polypeptide - protein Essential Amino Acids must be supplied in diet because body cannot synthesize them fast enough to meet requirements, examples - methionine, arginine, threonine, tryptophan, histidine, isoleucine, leucine, lysine, valine, and phenylalanine (MATT HILL VP) Nonessential Amino Acids essential to the animal, however, they normally are synthesized or are insufficient quantity in the diet and need not be fed to the animal Protein Analysis determine N content and multiply by 6.25 (100/16% N in protein) average Nitrogen content of Protein is 16%, crude protein and digestible protein
