When is brooding management in poultry done?
In the first 14 days period of the broiler poultry life.
How many weeks does a broiler stay in a broiler house?
Brooder up to harvest time (5-6 weeks of age)
How many weeks does a layer stay in a layer house.
Over 18 weeks up to 72 weeks.
It is a method of ventilating a barn system designed to maximize air exchange rates and air velocities over the birds.
Tunnel ventilation.
What are the benefits of tunnel ventilation system?
- Decreased heat stress-related mortality.
- Improved weight gain
- Better feed conversion
It is an art and science of rearing baby chicks either by natural or artificial heat.
Brooding
What is the temperature for brooding?
31.1-33.3 C for 24 hours from hatching.
T/F: Newly hatched chicks are cold blooded until 4-5 days.
True, because there thermoregulatory mechanism is not yet fully developed.
Factors affecting chick quality
- Temperature
- Humidity
- Chick holding
What is the temperature for chicks ages 1-7?
32.2-35 C
What is the temperature for chicks ages 8-14?
29.4-32.2 C
What is the temperature for chicks ages 14-21?
26.7-29.4 C
What is the indication of the right brooding temperature?
If the chicks are evenly scattered inside the brooding house.
What is the indication of extremely low temperature?
When chicks pile on the top of the other, stay together near the source of heat.
What is the indication if the temperature is too high?
Chicks move away from the source of heat, chicks spread their wings panting and drink a lot of water.
