One of the important factors that influence the physiological state and productivity of cows is humidity in the livestock area. It is known that 10-15 % of water vapour with respect to the total amount of vapour emissions is released from cattle manure. The aim of this study was to identify the dependence of the amount of moisture released from the stored manure on its humidity, storage time and temperature. It was found that under natural manure moisture of 85-86 % and air temperature of 26-28 ºC, the most intense release of water vapour from manure occurs in the first 5-6 hours, then the emission process stabilizes. The absolute humidity in the laboratory installation increases from 16.5 to 32.8 g•mE-3.
