Comparative study of semen physical characteristics and DNA sperm integrity in different breeds of falcon in Iraq

Abstract

This study was conducted to evaluation of semen quality with the DNA integrity in the season of falcon in Iraq in the different breed (Saker falcon Falco peregrines, and Falco tinnunculus) due to selection of breeding falcons used in the reproduction .the objective of study was to characterize semen quality in the deferent species of falcon. A total of 24 semen sample were collected from males by massage method. Semen parameters include mass activity, individual motility, dead and alive, abnormality and DNA integrity. Mass activity varied between breeds mass activity observed significant (P≤0.05) in the middle period of season, individual motility shows significant between initial, middle and later of season (P≤0.05). The evaluation of viability show no significant between breeds. Some teratospermia recorded, micro-head, tailless, and immature sperms in the different breeds with no significant differences. DNA integrity revealed significant among the individual males (P≤0.05). In conclusion the season of reproduction in Iraq play a role of semen viability and quality between different falcon breeds in Iraq.
