This study presents and discusses the results of 2-year measurements of air temperature, air humidity, litter temperature and litter moisture in a broiler house and of ground temperature below the floor and outside the building. Except temporary overheating, air temperature was found to conform to animal breeding standards. Air humidity was too low at the start of rearing and had to be additionally increased. It was subject to considerable fluctuations in the summer cycles. Litter studies showed that broiler chickens were exposed to adequate temperature for 20 days during the winter production cycle and for just 7 days during the summer cycle. Changes in litter moisture showed an upward trend in time. Litter moisture was greater next to walls than in the centre of the production facility. The time course of litter moisture was approximated by a quadratic function. Results of ground temperature measurements revealed considerable heat accumulation in the ground and its cooling during technolo.
