COMPARATIVE EVALUATION OF FRESH SEMEN PARAMETERS OF SAHIWAL BULL ALONG WITH THEIR METHODOLOGY.

The present study was conducted on four healthy breeding Sahiwal bulls with the aim to evaluate fresh seminal characteristics of Sahiwal bull along with their methodology. Physio-morphological seminal attributes of ejaculated semen were evaluated and recorded. Overall mean seminal volume irrespective of the bull was recorded as 5.83 ± 0.15. Overall mean seminal pH in the freshly collected semen of Sahiwal bull was 6.71±0.02. Overall mean mass motility of spermatozoa in the freshly collected semen of Sahiwal bull was 4.78 ± 0.05. Seminal mass motility did not differ significantly amongst different bulls. Overall mean sperm concentration in the freshly collected semen of Sahiwal bull was 1434.72 ± 276.42. Mean value of bull number S-109 was significantly higher compared to other bulls. Overall mean percentage of live spermatozoa in freshly collected semen of Sahiwal bull was 92.91 ± 0.59. Mean value of bull number S-103 and S-109 was significantly higher as compared to other bulls. The overall mean percentage of progressively motile spermatozoa in freshly collected semen of Sahiwal bull was 84.06 ± 0.97. The progressive motility did not differ significantly amongst different bulls. [ABSTRACT FROM AUTHOR]
