Summary
<p>This study was conducted to evaluate the effects of in ovo injection of coenzyme Q10 and maltodextrin into the amniotic sac on incubation performance, chick quality, immune organ weights, and antioxidant enzyme activities. As trial material, 278 broiler breeder eggs were obtained from a commercial breeding farm. Fertilized eggs were randomly divided into four treatment groups, including one control group, and placed in an incubator to be incubated under standard incubation conditions. On the 17th day of incubation, the second group, designated as the negative control group, received an injection of distilled water, while the third group received 0.2 ml of coenzyme Q10 (98%) and the fourth group received 0.2 ml of maltodextrin solutions. No treatment was applied to the control group eggs. At the end of the trial, there were no significant differences among the treatment groups regarding hatchability, incubation performance, and embryonic deaths. However, chick weights and relative chick weights, as well as the hatch window, were significantly affected by the in ovo application of coenzyme Q10 and maltodextrin (P<0.05). Some organ weights related to the immune system also showed significant differences among the groups. In hatchlings, alanine aminotransferase (ALT), aspartate aminotransferase (AST), catalase (CAT), nitric oxide (NO), and corticosterone levels were not affected by the applications of coenzyme Q10 and maltodextrin. However, differences in malondialdehyde (MDA) and superoxide dismutase (SOD) concentrations in the maltodextrin group indicated weak oxidative defense. In conclusion, it can be stated that in ovo injection of coenzyme Q10 during the incubation period is an effective method for protecting chicks against the risk of lipid peroxidation caused by hatch stress.</p>
