definition of Nutrition
What is the steps in which a living organism takes in food to help with growth, tissue repair and replacement or elaboration of products?
dry matter definition
proximate analysis definition
what is use to desrcribe feedstuff?
digestion definition
what is preparation of food for absorption?
growth trials are...
what is gain in body weight during a period of feeding a test diet?
Definition of nutrient
What is any chemical element or compound in the diet that supports normal reproduction, growth, lactation, or maintenance of life?
ash definition
what is total minerals?
simple way to determine dry matter
What is to put in oven, leave until all free water is evaporated?
absorption definition
what is processes that result in the passage of small molecules from the lumen of the GIT through mucosal cells lining the surface of the lumen and into the blood or lymph systems?
digestion trials are...
what is determine the amount of nutrients in a feed that is absorbed from the GI tract?
Definition of essential nutrient
What is required in the diet because they cannot be synthesized by the body in sufficient amounts so to satisfy metabolic needs?
amount of nutrients animals should get
What is 40 nutrients?
fractions of dry matter include
what is water, crude protein, ether extract, ash, crude fiber, nitrogen-free extract?
saliva definition
what is helps form a bolus, enzyme source, moistens mouth and aids in taste?
apparent digestibility formula
what is nutrient intake - nutrient in feces / nutrient intake x 100
Animal Nutritionist, what they do
What is formulate diets or supplemental feeds that are palatable to ensure an adequate intake for the purpose desired?
plant composition dependence
what is stage of growth and species of plant?
other methods of proximate analysis include
what is neutral detergent extraction, acid detergent extraction, pH, bomb calorimetry, amino acid analysis, atomic absorption spectrophotometry, gas-liquid chromatography, infrared?
digestibility definition
what is digestion and absorption?
batch trials are...
what is get rumen fluid, remove food particles, add buffer to simulate saliva and then add the sample being tested?
Founder of the science of nutrition
who was Antoine Lavoisier?
partial digestion definition
what is different parts of digestive tract studied and most information found in ruminants?
nylon bag technique is...
what is sample being tested, placed in nylon bag which is then suspended in rumen of an animal with a rumen fistula?
