FIELD: poultry farming. SUBSTANCE: method involves withdrawing broiler chickens from hatching chambers; exposing to pulsed electromagnetic radiation, with mode of operation being 2,000 V, current frequency of 50 Hz at triple-pulse action for 15 sec, and 2,500 V, 50 Hz at single-pulse action. Method allows chicken safety to be increased by 13.1-11.2%, blood serum lysozyme activity to be increased by 5.44-5.4%, bloods serum germicidal activity to be increased by 5.0-3.2%, live weight to be increased by 30.4-37.4 kg per 1,000 beasts. EFFECT: increased efficiency by improved keeping conditions. 2 tbl, 3 ex
