Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 8
Abstract
Objective: In recent years, antibiotics have been used widely in the glob to prevent and treat bacterial diseases. They injected into eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major concern. There is little information available about the safety of tetracycline drugs in the embryonated eggs of the birds. The objective of this study was to evaluation of the effect of doxycycline on the viability of the quail embryo during the first trimester of the incubation period. Methods: Fertile quail eggs were divided into two equal treatment groups. The uninjected group and doxycycline-injected group whose individuals were injected with doxycycline injectable solution at a dosage of 10 mg per Kg egg-weight. Embryos monitored daily during incubation until day 6 after which; they were examined for viability. Results: Results showed that 72% of embryos were alive in the doxycycline-injected group. Based on findings, it is concluded that doxycycline at abovementioned concentration has no severe lethal effect on the quail embryo. So, doxycycline egg-injection can be used to eliminate pathogens and prevention of egg transmission of the disease.
