SUMMARY
A study was conducted to assess the semen quality using Resazurin Reduction Test (RRT) in Jerseyand Jersey cross bulls. A total 36 fresh ejaculates were collected for evaluation RRT, sperm motility,acrosomal integrity and sperm concentration. The mean value of RRT in bulls was 15.770.85minutes.Statistical analysis revealed that RRT was highly significantly (p<0.01) and positivelycorrelated with sperm concentration (r=0.769), sperm motility(r=0.858) and acrosomal integrity(r=0.515), hence it may be helpful in evaluating the quality of semen in bulls.
