This study was carried out to investigate the effects of in ovo feeding of L-carnitine and Satureja Khuzistanica extract on hatchability, post-hatch performance and carcass traits in broiler chickens. A total of 560 fertile eggs of Ross 308 strain (36-wk-old breeder flock) were assigned randomly to seven treatments with four replicates and 20 eggs per replicate. Treatments included control grou...

    Previous studies indicated the positive impact of dietary supplementation of arginine on meat quality and growth, though there is no report regarding the effect of in ovo injection of arginine on meat quality. So, the aim of this study was to evaluate the effect of in ovo injection of different levels of L-arginine on hatchability, growth performance, and meat quality of Ross 308 broiler ch...

The aim of this study was to determine effect of in ovo injection of nanoparticles of zinc oxide on hatching, growth performance and carcass yield of broiler chicks after hatching. In total, 324 fresh hatching eggs were randomly distributed into six treatment groups of 54 eggs per treatment with three replicates of 18 eggs each, and injections were performed on day 15 of incubation. The treatme...

   In-ovo injection of anti-aromatase compounds have been taken into consideration by researchers in order to achieve a higher male to female sex ratio, higher economic impact, higher growth rates and better feed conversion ratio in broiler industry.  This research was conducted to find out if in ovo injection of aqueous and alcoholic extract of tomato can affect sex differentiation, sex ratio,...

The purpose of this study was to determine the effects of in-ovo injection of oil-extracted propolis on the growth performance and immune status of broiler chicks (Ross 308) after hatching. A total of 324 fresh hatching eggs were randomly distributed into six treatment groups of 54 eggs per treatment with three replicates of 18 eggs each. Treatments included sham as negative control (without in...
