APPARATUS FOR EXPOSING BIRD EMBRYO TO PULSED ELECTROMAGNETIC FIELD

摘要

FIELD: poultry farming, in particular, egg incubation under intensified bird reproduction and keeping conditions. SUBSTANCE: apparatus has casing, metal plate attached to upper part of casing, magnetic core made from electrotechnical steel and positioned in lower part of casing. Magnetic core is provided with slots for receiving three-phase winding. Egg tray is movable in inductor along guides. Three-phase winding is connected in phase-by-phase manner to outputs of single-pole pulse amplifiers, whose inputs are connected to DC sources and pulse former. Action of travelling pulsed magnetic field with frequency equal to multiple bird's heart rate causes resonant effect. EFFECT: increased efficiency and egg yield. 3 dwg
