METHOD FOR INCREASING IMMUNITY TENSION TO NEWCASTLE DISEASE Russian patent published in 2008 - IPC A61N5/08 A61N5/67 A61K39/17 A01K45/00 

FIELD: veterinary science, poultry science.

SUBSTANCE: the present innovation deals with pre-incubation treatment of hen embryos with the light of fluorescent lamp DNESG-500 at wave length of 630-650 nm, average dosage at egg surface being 23.1 erg at exposure of 17 sec, with He-Ne laser LHN-104 at wave length of 632.8 nm, power density of optic flow at egg surface being 50 mW/sq. cm·sec at exposure of 3 sec, with mercury-quartz lamp DRT-400 at wave length of 400/185 nm, average dosage at egg surface being 20 merg/h at exposure of 3 min. Moreover, such treatment should be fulfilled before laying for incubation on the 6^th, 12^th, 18^th d of incubation and in daily chickens 4-fold at 5-min-long interval. Then comes disinfection from all the sides with two bactericidal lamps BUV-15 at wave length of 254/800 nm, nominal power at egg surface being 15 W at exposure per 5 sec and with three bactericidal lamps BUV-30 at wave length of 254/800 nm, nominal power at egg surface being 30 W at exposure of 17 sec. Incubated broiler chickens should be immunized with the vaccine of "Bor-74 BGNKI" strain. The innovation enables to increase specific resistance to Newcastle disease in poultry.

EFFECT: higher efficiency.
