Nutrition Flashcards
Transport or nutrients and excreta, cell component, temperature regulation, lubrication, metabolism
Water
Dietary energy supply, provides insulation and protection, source of essential- cell structure, precursor of hormones, serve as the carrier of fate soluble
Fats and lipids
C, B-complex
Water soluble
A,D,E,K
Fat soluble
Preparation of food for absorption, reduction in food particle size
Digestion
Passages of small molecule into the systems, passage is from the GI tracts -> cell
Absorbtion
Sum of all physical & chemical processes that occur within a biological system
Metabolism
Particle size reduction: mastication
Mouth
Little digestion, simply movement
Esophagus
Storage compartment, physical breakdown of feed, chemical digestion
Stomach
Enzymatic digestion, absorption of nutrients
Small intestine
Water resorption, storage of undigested food, microbial fermentation (limited absorption)
Large intestine
No chewing, instead of mouth
Beak
Enlargement of esophagus, more area than stomach
Crop
Secretes HCl, does not mix/grind
Proventriculus
Grinds feed to smaller particles, birds on fine rations could survive without it
Gizzard
Site of microbial fermentation in horse, production of volatile fatty acids, production of microbial protein, synthesis of B-vitamin by the microbes
Cecum
Eating own feces
Coprophagy
Use died energy (CHO) and N for own growth, excrete VFAs as a waste product
Microbe
Digest microbes to retrieve proteins & vitamins, VFAs (acetate, butyrate, propionate)
Animal
Measure of energy, other measures of energy used: NET ENERGY
TDN total digestible nutrients
Measure of lowely digestible material
Crude fiber CF
Measure of amino acids / nitrogenous cpds
Crude Protein CP
Feed constituent that is vital and functions in the support of life
Nutrient
