Abstract
The data were recorded during 1980-85 on crossbred
bulls maintained at the Semen Production Unit, Qadirabad,
district Sahiwal. From 2374 ejaculates it was found that volume per ejaculate was 6.65, 6.52, 5.94, 5.51 and 5.95 ml during
winter, spring, summer dry, summer wet and autumn seasons, respectively (A, B, C, D and E) with an overall average
of 5.98 ml per ejaculate. The motility percentage was 49.60,
46.25, 46.92, 40.39 and 44.35 while sperm concentration was
647.81, 714.51, 700.97,508.31 and 597.28 million per ml during
A, B, C, D and E seasons respectively. It was concluded that
season had no significant effect on volume, motility percentage and sperm concentration in crossbred bulls.
