Digestive Physiology
process
Digestion
Absorption
Ingestion
Elimination
Food Absorption
Absorption of amino acids and glucose
Absorption of amino acids and glucose
Digestion amd absorption of lipid
Mineral absorption
Food Intake
How animals obtain their food
depend on size
Sit and wait strategy
Reptiles, frogs, fish
Graze or browse on plants around
spend less energy, low food quality
Hunt, identify, chase and capture
spend more energy. high food quality
food that requires handling
for examples: large prey items and hard, fibrous food require a lot to handling
measuring food intake
Voluntary Food Intake (VFI)
easy to determine if animal is tame, amount of food given - leftover = VFI
difficult to determine for wild animals
Control of food intake
Short term control
Long term control
Metabolites detection
Hunger and Satiety
Sensors
Large Intestine
absorp 90% of water
Eliminated feces
beneficial gut flora
Vit B and K
Biotin
fermenting dietary fiber into short-chain fatty acids
generate gases
Food digestion
Classification
