dc.description.abstractA study was undertaken on the consistent occurrence of sperm abnormalities in a Jersey bull maintained in an organized frozen semen production station. Data on semen collections and a representative ejaculate from the bull in question were collected to evaluate the semen characteristics. From the records it was observed that 74.5% of the ejaculates were rejected as fresh semen for poor semen quality especially in sperm morphology. The representative semen sample also revealed low sperm concentration, poor sperm motility and sperm abnormalities up to 82.4%, of which 65.2% of the spermatozoa showed ‘Dag-like’ defect. Majority of the spermatozoa in the ejaculate also showed abnormal acrosome status (75.1%). Consistent occurrence of high proportion of ‘Dag-like’ sperm defect and acrosome abnormalities suggested a genetic cause.en_US
