total of 270 quail fertile eggs were set in hatchery. experimental groups including: negative control (neither received probiotic treatment nor challenged by salmonella), positive control (challenged by salmonella but not probiotic treatment) and 7 in hatchery administration methods: in ovo injection, spray, oral gavage, cloacal drinking (cloacal inoculation), cloacal drinking – in ovo injectio...

This study was conducted to evaluate the long-term effects of in ovo injection of nano-silver, thyme and savory extracts in broiler breeder eggs on growth performance, lymphoid organ weights, immune and blood parameters and bone mineral concentration of broiler chicks. A total of 560 fertilized broiler breeder eggs were divided into 7 groups. On d 5 of incubation, eggs were treated with the fol...

introduction: many birds do not have access to feed until 48 h after hatching (27). in ovo injection technology is a practical means for safe introduction of nutrients into developing embryos, including amino acids, carbohydrates, vitamins, l-carnitine, and hormones which may benefit post-hatch growth and bw gain (19, 36). the objective of this study was to evaluate the effects of in ovo inject...

Chicken embryonic retina is an excellent tool to study retinal development in higher vertebrates. Because of large size and external development, it is comparatively very easy to manipulate the chick embryonic retina using recombinant DNA/RNA technology. Electroporation of DNA/RNA constructs into the embryonic retina have a great advantage to study gene regulation in retinal stem/progenitor cel...

First, this study aimed to evaluate the effects on hatchability of in ovo supplementation beta alanine (βA). Second, it assessed performance, meat quality and serum constituents broiler chickens βA injection with feed for first seven days after hatching. For purpose, 960 fertilized chicken eggs were distributed hatchery trays four treatment groups six replicates day 17 incubation. The consisted...
