METHOD FOR INCREASING IMMUNITY AGAINST NEWCASTLE DISEASE Russian patent published in 2008 - IPC A61K39/17 A61N5/08 A01K45/00 

FIELD: veterinary science.

SUBSTANCE: the present innovation deals with heating hens' embryos with light of fluorescent lamp DNESG-500, wave length being 630-650 nm, average dosage at eggs surface being 23.1 erg at exposure of 5 min, irradiation with He-Ne laser LHN-104, wave length being 632.8 nm, power density of optic flow at eggs surface being 50 mW/sq. cm, with mercury-quartz lamp DRT-400, wave length being 400/185 nm, average dosage at eggs surface being 20 mErg/h out of "Bor-74 VGNKI" strain. Light treatment of embryos in the same mode and poultry immunization should be combined with eggs disinfection from all sides with two bactericidal lamps BUV-15, wave length being 254/800 nm, nominal power at eggs surface of 15 W and three bactericidal lamps BUV-30, wave length being 254/800 nm, nominal power of 30 W at exposures per 3 min. And poultry light treatment in the same mode should be carried out before incubation on the 6^th, 12^th, 18^th d of embryos development and in incubated day-long chickens. The innovation prolongs survival rate in broilers grown under industrial conditions being unfavorable on Newcastle disease.

EFFECT: higher efficiency.
