Heat and moisture loads and their variability under commercial conditions were determined by monitoring taree broiler breeder barns with partially slatted floors, one utilizing (deep-pit and two shallow-pit droppings storage systems. Data were collected for 24-h periods at regular intervals during the production cycles and under cold winter conditions. The bird total heat production in the three barns ranged from 67.7 to75.4kJ/(h.bird), while the latent hear, production ranged from 25.7 to 36.2 kJ/(h.bird). The proportion of sensible heat converted to latent heat by evaporation was 24 and 37% in the shallow pit barns, and 36% in the deep-pit bam. The ratio of latent to total heat in the exhaust air averaged 0.38, with the highest ratio occurring in the deep-pit barn.
