METHOD OF LIGHT-AND-LASER TREATMENT OF CHICKEN EMBRYOS Russian patent published in 1999 - IPC

FIELD: poultry farming. SUBSTANCE: prior to laying eggs for incubation and in process of the latter, eggs are treated four times with 6-days interval every 5 min in succession with light of gaseous-discharge lump ДНЕСГ-500 at wavelength of 630-650 nm, with average dose on surface of eggs equal to 23.1 erg in 5-s exposure. They were irradiated by helium-neon laser ЛГН-104 at wavelength of 632.8 nm, with optical flux power on surface of eggs equal to 50 mW/sq.cm in 2-s exposure. They are irradiated further by mercury-quartz lamp ДРТ-400 at wavelength of 185-400 nm, with average dose on surface of eggs equal to 20 mer/h and by two germicidal lamps БУВ-15 in 5-s exposure. As a result, output of conditional chickens increases by 19 per cent. Activation of broiler embryogeny is accompanied by rise of postembryonic violability. Preservation of poultry at end of fattening increases relative to control period by 9.3 per cent. By daily average growth of living mass experimental broilers surpass control ones by 12.6 per cent. EFFECT: enhanced efficiency. 4 tbl
