This study was carried out to evaluate the effect of age on the fresh semen quantity and quality of Madura bulls. One hundred and two semen samples collected from three Madura bulls aged at 4, 8, and 12 years old (34 samples of each bull) were involved in this study. All data were analyzed using one-way analysis of variance followed by post-hoc Duncan test. Interrelationship among semen volume, sperm concentration, and individual sperm motility was analyzed using the Pearson correlation test. Results showed that the semen volume significantly increased (P0.05) with individual sperm motility. It could be concluded that age greatly affects the fresh semen quality of Madura bulls. The fresh semen quantity and quality of Madura bulls reaching optimum performance at 8 years old.
