LIGHT-AND-LASER TECHNOLOGY FOR BROILER PRODUCTION Russian patent published in 2000 - IPC

FIELD: food industry. SUBSTANCE: hatching eggs prior to being placed in incubator, embryos in the course of embryonic development, and one- day baby chicks are sequentially exposed four times every 5 minutes to gas-discharge lamp DNESG-500 at wavelength of 630-650 nm, mean dose on egg surface of 23.1 erg for 15 s, to LGN-104 laser beam at wavelength 632.8 nm, optical flux power on egg surface of 50 mV/sq. cm per s for 2 s, to mercury-quartz lamp DRT-400 at wavelength of 400/185 mn, mean dose on egg surface of 20 merg/h, and to bactericide lamp for 5 s with the result that fertility of eggs influencing the number of chicks hatched has raised by 3.0% and their post-embryonic vitality as well as their safety by end of feeding relative to control value has increased by 10%. High vitality of poultry during post-incipient period of development was combined with high energy of growth. Mean daily increase in chick mass to broiler size was greater by 14.5% compared with control value. EFFECT: reduced time required to grow chick to broiler size. 4 tbl
