The present investigation was carried out to study the effect of vaccination on the sexual behavior of six Pandharpuri buffalo bulls. The bulls were vaccinated against HS-BQ in July and FMD-I in September and FMD-II in February. The work was divided into four periods, viz., control/pre-vaccination period (Nov-Jan), and post-HS-BQ, FMD-I and FMD-II vaccination periods. Overall mean libido and sexual behavior score of bulls during the pre-vaccination period was 90.76±0.19 percent, which significantly decreased for first three (76.65±2.79 to 79.17±2.39), two (77.50±1.71, 76.67±3.07) and one (79.15±2.71) week after FMD-II, FMD-I, and HS-BQ vaccination, respectively. Mean reaction time (seconds) of bulls during vaccination free period was 46.25±0.14, it increased significantly in first four (59.17±2.01 to 56.67±2.11), three (56.67±2.11 to 57.50±2.14) and one (57.50±2.81) week post-FMD-II, FMD-I, and HS-BQ vaccination, respectively. FMD-II (February) vaccination had a more harmful effect on sexual behavior and reaction time compared to FMD-I (September) vaccination, perhaps due to the succeeding summer season. It was concluded that sexual rest should be recommended for three, two and oneweek post-FMD-II, FMD-I and HS-BQ vaccination, respectively, return to normal sexual behavior in Pandharpuri buffalo breeding bulls.
