abstract
Present study was undertaken to record the sperm abnormalities in eight Jersey bull maintained at Livestock development Board Sperm station, Palampur using Rose Bengal staining. A total of sixty four ejaculates, eight each from eight mature Jersey bulls, twice in a week, were collected and evaluated for morphological abnormalities at four stages of semen processing viz, post-dilution, equilibration, post thaw and 1 hr post thaw incubation. Sperm abnormalities were classified into head, midpiece and tail. Significant difference (p<0.05) was observed between head, midpiece, tail abnormalities at equilibration, post thaw and 1hour post thaw incubation. However, at post-dilution stage midpiece and tail abnormalities differed significantly. Since the different abnormalities of head, midpiece and tail were in the permissible limit this making ejaculates suitable for cryopreservation and its usage for artificial insemination at farmer’s doorsteps.
