Usage of systems with mechanic ventilation not taking into account high spends of electricity (6,4-12,3 kg u.t. per 1 с of weight gain) promotes the better microclimate parameters. It affects the bulls live weight growth at 1,9-5,2% and forage spends decrease at 1 с of weight gain at 2,8-5,9%. Cutting the ventilation volume at the 1st growing phase in winter period from 20-25 m3/h to 10-15 m3/h per 100 kg of live weight and from 40-50 m3/h to 25-30 m3/hin transition period let us decrease the annual energy and natural gas spends for ventilation and heating at 10-16% compared to the existing parameters
