EFFECT OF SELENIUM NANOPARTICLES ON BROILER PRODUCTIVITY AND PHYSIOLOGICAL RESPONSE USING RADIOIMMUNOASSAY TECHNIQUE

Abstract

The present study was carried out at Poultry Production Research Farm, Poultry Research Unit, Biological Application Department, Nuclear Research Center, Egyptian Atomic Energy Authority, during the period from March to May 2017, and the chemical analysis were conducted in the Biological Applications Department laboratories, Nuclear Research Center, Egyptian Atomic Energy Authority. A total of 210 broiler breeder eggs (Habbard Star-Bro) were obtained from a local hatchery (El-Tokhy Co., New Salhia, Egypt) from a maternal flock 54 week age. Eggs were incubated at 37.8ᵒC and 60% RH. Upon arrival, the eggs were individually weighed and divided into three in ovo treatment groups. The first treatment non in ovo-injected, and considered the control group, while the second and the third treatments were in ovo injected with 100 μL of nano –Selenium(elemental selenium ) with concentrations of 5, 10 ppb respectively at 14 day of incubation. The hatched chicks, from each treatment were randomly divided into two treatments , once was added 10 ppb nano -Se per kilogram ration, and the other without any additive, it had became six treatments .
