Dissertation note In this study twelve normally producing breeding bulls three of each Sahiwal and Friesian breeds and six bulls of 50% Cross-bred were selected. The mean volume of ejaculates were 4.87, 4.22 and 5.95m1 in Sahiwal, Friesian and Cross-bred, respectively. There is no significant difference among the volume of breeds during the months May, June and July. The semen concentration were 637.369, 606.554 and 312.806 million per ml in Sahiwal, Friesian and Cross-bred. However, the concentration of spermatozoa in Cross-bred were significantly lower (P<0.01) as compared to Sahiwal and Friesian bulls.
The overall average values for head abnormalities percentage were significantly lower (P <0.01) in Sahiwal vs Friesian and Crossbred (2.65 vs 7.20 and 8.90%) respectively during summer season.
The neck abnormalities percentage were significantly lower (P<0.01) in Sahiwal vs Friesian and Cross-bred 1.13 vs 3.52 and 5.59% respectively during summer season. Similarly the values of mid piece abnormalities percentage were significant higher in Cross bred vs Sahiwal and Friesian (2.04 vs 0.60 and 1.83%) respectively during summer season. The same results pertaining to protoplasmic droplets and tail abnormalities were obtained.
The overall average abnormalities percentage in spermatozoa of Sahiwal breed were significantly lower vs Friesian and Cross-bred (8.64 vs 21.32 and 27.67%) respectively during summer season. These results indicated that Exotic breed (Friesian) as well as Cross-bred have poor adaptability against the stress of the high temperature during summer season, so they produce lower quality semen.
