ANSC*4100 Poultry Housing ACTUAL UPDATED QUESTIONS AND CORRECT
ANSWERS
C
Terms in this set (21)
Egg Production
Broiler Production
Poultry Demographics Turkey
Ducks
other fowl
Animals:
- Pullets (non-layers)
- Layers (15 WOA start)
- Layer-Breeder Management (breeding laying hens)
What is "Egg Production" composed of?
(Animals and Housing Structures) Housing:
- Conventional Cages
- Enhanced Cages
- Aviaries
- Alternative Cages
VERY NARROW ZONE FOR BOTH UCT and LCT!
* Very little le-way for extreme temperature fluctuations.
Trends of Upper and Lower Critical Meaning... temperature regulation in poultry housing is important.
Temperatures in Poultry?
Exception: Turkeys
- better LCT range (can withstand colder temperatures better than other poultry)
- still not great though (view graph)
What does it mean that poultry are They use metabolic and behavioural modifications to maintain a constant
"Endothermic Thermoregulators"? temperature.
Shivering Thermogenesis
Panting: Evaporate water to dissipate heat through respiration
High Metabolic Rate
- increases O2 consumption to support metabolism
- energy expenditure for thermoregulation
How do Poultry Thermoregulate?
"Double Circulation"
- the same as mammals
- the idea that blood will pass through the heart twice before being pumped to
systemic circulation) (enters through the right atrium, pumped from right ventricle to
the lungs, from the lungs to the left atrium, then from the left ventricle to system
circulation)
why does this matter? ("cool the temperature they respire")
- blood entering the lungs will be cooled/heated depending on the air temperature.
Do Poultry Sweat? No.
