RESUMO
The surroundings of wild and captive birds are divergent in existence. Wild birds inhabiting their natural environment have unlimited resources availability. They face variety of captivity stresses when moved from wild habitat to caged enclosures. The effect of similar captivity stresses on the DNA of birds living in cages for longer stretches of time is addressed in this study. The laboratory analysis to investigate DNA damage in Pavo cristatus was performed using single-cell gel electrophoresis (SCGE) or comet assay. Our results showed that measurable DNA damage was observed in Pavo cristatus species. Endogenous stress factors owing to long-term captivity were responsible to cause this damage. The caged conditions provided to the captive birds can be improved in order to prevent DNA impairment. Moreover, appropriate monitoring and effective management are necessary on continual basis to ensure the well-being of caged birds.
