LPM 221: Commercial Poultry Production and Hatchery Management (1+1)

VENTILATION

• Ventilation must be adequate and should be based on a minimum of eight complete changes of air every hour.
• No specific system is recommended, but the air inlets must be provided to prevent straight draughts; outlets whether fan assisted or natural draught must not be placed immediately above the upper outlets of the incubators since this will interfere with the proper internal ventilation of the incubators.
• Incoming air should be cooled in the summer to keep the room temperature around 18.3 to 21.1^oC which is not too warm to the incubators.
• More air should be moved through the hatchery rooms during warm seasons than cool.
• Therefore, rheostats should be installed on all ventilating fans to provide increased or decreased air flow to help control room temperature.
