MICROCLIMATE PARAMETERS AND VENTILATION INSIDE THE BARNS IN THE LOWLAND REGION OF BOSNIA AND HERZEGOVINA

Purpose of this paper is analysis of microclimate parameters in dairy cow barns in Bosnia and Herzegovina (Republic of Srpska), and examine the impact of the ventilation on the microclimate inside the barns. The study included 38 dairy barns in the lowland region of Bosnia and Herzegovina (Republic of Srpska), during the winter season. The following microclimate parameters were measured: air temperature, relative humidity of air, air velocity and concentration of gases (NH3 and CO2). Statistically significant correlations were determined between NH₃ concentration and air temperature (P<0,001) and between temperature and concentration of CO₂ (P<0,05). Also, are established positive and statistical significant correlation between manure gases (NH₃ and CO₂). The research has also shown that the average concentration of CO₂ in relation to the open area in the barn statistically significant (P
