Moisture Production rate (MP) from animals and their housing components provide fundamental data for the engineering design of a building environmental control system. MP of a commercial laying hen house with manure belt and tunnel ventilation was measured for a one-year period. The MP values included both latent heat loss of the birds and evaporation of moisture from the feces on manure belt. During the one-year measurement period, MP varied from 1.57 to 11.74 g H2O h -1 kg -1 with housing temperature ranging from 18 to 32 o C. Regression equations were established to predict MP of the commercial layer house over common ranges of outside temperature (-17 to 29 o C), RH (30% to 98%), inside temperature (18-32 o C), age condition (20- 42 wk and 97-119 wk) and lighting condition (light or dark). Results from this study provide new data for updated standards to be used in design and operation of laying hen houses.
