Abstract

Heat and moisture production of layers under constant and cyclic temperature and humidity environments were measured and compared to published values. These data were obtained from two environmental chambers each with a capacity for 48 caged birds. The environmental chambers were used as calorimeters in which flow rates and temperatures were measured in the various air streams with pitot tubes and thermistors. Sensible heat production for the constant thermal environment compared favorably with published values. Latent heat production differed from published values, this difference was attributed to evaporation from fecal matter which was a part of the measured values. Preliminary results from the cyclic environments are also presented.
