The aim of this work was to examine consequence of riboflavin in ovo injection on the chicken embryo development and chickens production parameters. The aim of the experiment was to investigate the influence of high doses of riboflavin (0, 300, 1,500 and 3,000 ?g/egg, n= 1,200 eggs from the broiler breeder flock of Ross 308 line) injected in ovo on 0. or 6. day of incubation for hatching and growth during the fattening. It was proved that in ovo injection of riboflavin before the beginning of incubation caused mortality increase of embryos in the early stages of embryogenesis. 3,000 µg/egg riboflavin application decreased chickens fattening rates. Summarizing the data presented here suggest that riboflavin in ovo injection affect hatching and some aspects of chicken metabolism. Further studies are needed to explain the role of riboflavin in chicken embryogenesis.
