Alternative / Ventilation
A general rule for figuring required fan
capacity is four cubic metres of air
movement per kilogram of body weight per hour (one cubic foot per minute per pound of body weight).
The birds optimum environmental temperature and humidity should be in the range of 21 - 27°C (70 - 80°F) and 40 - 60% relative humidity.
Ventilation
Ventilation should be used as a major management tool to provide the optimum micro-environment per bird.
Controlled ventilation can do a great deal to dilute pathogenic organisms as well as provide an optimum micro-environment when ventilation equipment is designed and operated to give correct air speed and direction.
