Description: Two commercial barns for rearing pullets for egg production were monitored for 24-h periods during each month of the 18- to 20-wk rearing cycle to ascertain heat and moisture loads within these facilities. One barn was representative of the cage-rearing system and the other of on-floor rearing. Total heat production of the White Leghorn type pullets ranged from 2.3 to 30.5 kJ/(h.bird) over the rearing cycle, while the non-bird latent heat production ranged from 0.6 to 6.4 kJ/(h.bird). Approximately two-thirds of the total heat loss by ventilation was in sensible heat form. The conversion of sensible to latent heat in evaporation of moisture ranged from 12 to 38% of bird sensible heat production over the rearing cycle.
