Abstract: The present research was undertaken to study the effect of season on the sexual behaviour parameters viz. Reaction time, Erection time, Ejaculation time and Number of thrusts of Marwari stallions. The work was conducted in the Department of Veterinary Gynaecology and Obstetrics, College of Veterinary and Animal Science, Bikaner, Rajasthan and ICAR-NRCE, Equine Production Campus, Bikaner, Rajasthan. A total of six Marwari Stallion were maintained under uniform and standard conditions for the research. The overall mean values of reaction time was observed 64.17±3.02 seconds in the breeding season and 166.31±5.17 seconds in the non-breeding season for Marwari stallions which was significantly (p<0.01) higher in the non-breeding season than the breeding season. The overall mean erection time was significantly (p<0.01) higher in the non-breeding season as compare to breeding season with the range of 38.09±2.04 seconds in the breeding season and 52.12±4.35 seconds in the non-breeding season. A non-significant difference was recorded among breeding and no breeding season and overall mean values of ejaculation time for the Marwari stallions was 25.72±0.89 seconds in the breeding season and 29.48±2.55 seconds in the nonbreeding season. The overall mean numbers of thrusts were 3.75±0.24 in the breeding season and 5.08±0.28 in the non-breeding seasons which was non-significant among the seasons. The study concluded that sexual behaviour parameters are affected by seasons and give better performance in breeding season comparatively.
