Results of realized in the conditions of the Republic of Belarus energy estimation of veterinary and hygienic methods of microclimate organization in livestock buildings were presented. As a result of the conducted veterinary and hygienic estimation of conditions of cattle maintenance in premises at cattle breeding farm in Vitebsk region (Belarus) it was found out, that one of the reasons of decreasing in productivity and livability of calves was the unsatisfactory microclimate at livestock buildings. In particular, air temperature in calf houses was marked below standard on 25-29%. Indices of the relative moisture exceeded the standard requirements on the average on 7% and concentration of ammonia - on 19-24%. Natural and artificial light exposure at premises did not correspond to veterinary and hygienic requirements. Research results analysis showed that a principal reason of unsatisfactory microclimate condition was the unsatisfactory system of ventilation, application of artificial prompting of air that involved the exceeding expenses for the electric power. The veterinary and hygienic measures with regard for power economy were characterized. It was stated that the proper use of ventilation, manure removing, feed-supplying and lighting systems made it possible to save up to 30% of power energy
