    Abstract:
    Studied was the dynamics of the microclimate at the cow complexes in the district of Vidin, where cows are raised of the Dutch Black Pied, Bulgarian Simmental, and Bulgarian Red cattle breeds. The temperature and relative humidity dynamics of the air was followed up as well as the values of ammonia gas and carbon dioxide, the microbial contamination, the coefficient of natural illumination, and the level of noise. The effectiveness of the ventilation system was assessed by direct and indirect criteria as suggested by the authors. The veterinary and sanitary evaluation by individual elements of the microclimate is carried out on the basis of normative documents in the People's Republic of Bulgaria, USSR, and GDR.
