Abstract: Prior to this work, predicted the optimal values of temperature humidity regime in cowsheds, which is necessary in designing and operating the ventilation systems. In addition, investigate the operation of ventilation systems in two cowsheds by observing the temperature differences between indoor and outdoor air, indoor air relative humidity, CO2 concentration. Having performed analytical research has been drawn an equation, which relates the temperature differences between indoor and outdoor air with the indoor air relative humidity, outdoor climate conditions and thermal factors of cowshed. Experimental research were carried out in two production cowshed with different thermal factors (one cowshed uninsulated, another with insulated roof - partly insulated) and different operation of ventilation systems. Both cowsheds dimensions of the ventilation system were designed sufficient size. The difference between the predicted and observed temperature humidity regime of uninsulated cowshed was non- essential, and average relative humidity of the indoor air was in line with the minimum possible. But for partly insulated cowshed observed difference between indoor and outdoor temperature humidity was too much, and in winter the indoor air humidity usually exceed the minimum possible and sometime reached 100 %. That's shows that ventilation system management was poor
