Termini in questo insieme (40)
Nutrient
chemical substance in food that provides nourishment and growth
Feed
Any material given to animals for consumption
Food
substance consumed to provide nutritional support
Feed Stuff
single ingredient or material used in animal feed
Forage
plant material eaten by grazing animals
Diet
total feed consumed by an animal over a period of time
Ration
Amt of feed given to an animal in 24hrs
Absorption
process by which digested nutrients move from the digestive tract into bloodstream or circulation
Digestion
physical and chemical breakdown of food into nutrients that can be absorbed
Macro nutrient
nutrient required in large amounts, such as carbohydrates, proteins, fats, and water
Micronutrient
nutrient required in small amts such as vitamins and minerals
Macrominerals
Minerals required in large amts like calcium, phosphirus, potassium, sodium, and magensium
Microminerals
Minerals required in very small amounts; also called trace minerals.
trace minerals
Essential minerals needed in tiny quantities, such as iron, zinc, copper, iodine, selenium, and manganese
vitamins
organic compounds
Water Soluble Carbohydrate (WSC)
carbohydrates that dissolve in water like sugars, starches that provide energy
Forgut
digestion where microbial fermentation happens before small intestines in ruminants
Hindgut
digestion where microbial fermentation happens in the cecum/ large intestine after small intestine.
Ruminant
animal with multicompartment stomach that ferments feed before digestion like cattle sheep goat
coprophagy
The consumption of feces to recover nutrients not absorbed during the first passage through the digestive tract.
Crop
An enlarged pouch in the esophagus of birds used for temporary food storage
Rumen
largest compartment of a ruminant stomach where microbial fermentation happens
Gizzard
muscular stomach in birds the grinds food
sacculated
pouch like compartments used to increase fermentation capacity
Producer
organism that makes its own food usually through photsynthesis
Consumer
organism that obtains energy and nutrients by eating others
Gel Electrophoresis
A laboratory technique used to separate molecules such as DNA, RNA, or proteins based on size and charge.
Chromatograph
technique used to separate and identify components of a mixture
Gravimetric Procedures
Analytical methods that determine an amount by measuring weight.
Mass Spectrometry
A technique used to identify and quantify compounds by measuring their mass-to-charge ratio.
Colorimetry
A method that determines the concentration of a substance by measuring color intensity.
Kjeldahl Method
A laboratory procedure used to determine nitrogen content and estimate protein levels.
Ash
The mineral residue remaining after organic matter is completely burned.
Crude Protein
An estimate of total protein content based on the nitrogen content of feed
Crude Fiber
A measure of the less digestible structural carbohydrates in plants.
Lignin
A complex compound in plant cell walls that is largely indigestible and reduces feed digestibility.
Cellulose
A structural carbohydrate in plant cell walls that can be digested by microbial fermentation.
ERDN
estimate of digestible nitrogen in feed
UDN
Nitrogen remaining unavailable for digestion
Bypass protien
protien that esapes breakdrown in the rumen and is disgested in the small intestine
