Abstract

Five native buks aged between 2 to 2a years and weighing about 24.25±2.5 kgs were used to study the
seasonal variation in physical attributes of semen. Semen samples were collected twice in a week during winter and
summer seasons. The mean values for different semen characteristics were as follows, volume 0. 70±0.10 and
0.60±0.02, mass motility 4.46±0.06 and 4.34±0.08, individual motility(%) 81 .78±0.53 and 78.06±0.68, spenn
concentration (x I 09/ml) 2.45±0.31 and 2.35±0.02, live sperm count(%) 87.05±0.62 and 81.11±0.51, abnormal spenn
(%) 8.98±0.23 and 9.28±0.20 and intactacrosomes(o/o) 72.68±0.97 and 77.76±0.76 in winter and summer seasons
respectively. Seasons had significant effect on semen volume, individual motility, spenn concentration, live spenn
count, abnonnal sperms and intact acrosomes acrosomes where as mass motility did not significantly differ between
the seasons.
