The study evaluated and compared the sperm abnormalities in frozen–thawed semen namely head, mid piece and tail in pure and crossbred Jersey bulls in 36 ejaculates (3 ejaculates from each bull). The mean abnormalities of head, mid piece and tail between pure and crossbred Jersey bulls were 5.08 ±0.23 Vs.5.77±0.34; 5.94±0.32 Vs.5.23±0.37 and 6.66±0.55 Vs. 6.00±0.53, respectively which did not differ significantly (p>0.05). The incidence of asymmetric head, detached/free head, bent mid piece, free tail and highly coiled tail was higher in crossbred Jersey bulls and differ significantly (p<0.05) from pure Jersey bulls whereas volume, sperm concentration, post thaw motility, and plasma membrane integrity did not differ significantly (p>0.05) between the breeds. The percentage of sperm viability and acrosome intactness was significantly (p<0.01) higher in pure Jersey compared to crossbred Jersey bulls. On the basis of overall parameters, the quality of semen of pure Jersey bulls was good.
