Energy Sources Spends in Rooms for Blank and Conditionally Pregnant Sows in Winter Period

Abstract

Researches helped to determine that for blank and conditionally pregnant sows the most effective management technology is the technology of management in rooms with heat irradiation resistance coefficient for walls of 2,1 m²*^оS/Wt, floors - 2,5 m²*^оS/Wt, with automated ventilation system of negative pressure, with air heating during the cold period of the year by heat generator of direct effect, with automated system of dry feeding, with automated system of manure removal. The energy saving during the winter period 1 in room for blank and conditionally pregnant sows made 6,51 kWt/animal.
