Anabolism
Synthesis of complex molecules from simpler molecules
Catabolism
Breakdown of complex molecules to simpler molecules
Digestion tract is
A tube in the body
Feed must be
Broken down and moved to be utilized
Indigestible and unabsorbed nutrients are
Excreted
Digestion is
Breaking down of food
Absorption
Transfer of simple substances from the gastrointestinal tract to the blood and lymph system
Some feed is able to be
Broken down and absorbed readily
Some feed has
Higher Digestibility
Gross energy
Amount produced when feedstuff is burned
Digestible energy
Gross - fecal
Intake
Urge to eat
Enteric Nervous System
Brain of the gut
All mammal GI tract is
Controlled and monitored by ENS
Adiponectin

Hypothalamus and stomach cells
Ghrelin —- GI motility, gastric and pancreas secretion
Increases
What increases anticipation if a meal
