Abstract.

These investigations were conducted in a standard barn for 200

stanchion cows in the summer period with a special electronic device, the analysis of

the obtained data was made with the use of graphical information modelling, the results

demonstrated, that CO2 concentration was from 700 till 1200 ppm average and did not

exceed 50% of the maximum permissible concentration. The lowest CO2 concentration

was registered on the windward and leeward side of the barn; and the highest one was

registered about in 1.4-1.9 times higher in the central part of the barn.

Keywords:

information model, microclimate, carbon dioxide, barn.
