Koçlarda taze sperma parametreleri ve DNA bütünlüğü arasındaki ilişkilerin araştırılması

The aim of the present study was to evaluate the correlation between the routine semen analyses and sperm DNA integrity, as assesed by TUNEL in fresh semen of rams in Kivircik and Awassi breeds in breeding season. Semen was collected by electro-ejaculation five times every other day. For that purpose, 50 fresh ejaculates from 6 Kivircik and 4 Awassi rams were evaluated. The mean percentages of semen volume, concentration, mass activity, motility, acrosomal defects, HOST and DNA fragmentation of Kivircik and Awassi rams were 1.3 ml, 1.9 x109, 3.3 (0-5 scale), 72.6%, 13.2%, 73.6%, 16.2% and 1.0 ml, 1.9 x109, 3.3 (0-5 scale), 72.5%, 11.1%, 77.9%, 15.9%; respectively (P>0.05). Sperm DNA fragmentation was correlated adversely with semen volume (r=-0.329, P0.05), mass activity (r=-0.349, P0.05) and HOS test (r=-0.513, P0.05), mass aktivite (r = -0.349, P0.05) ve HOS testi (r= -0.513, P
