The present study was undertaken to investigate the effect of temperature humidity index (THI) on various seminal attributes in buffalo bulls. Forty one ejaculates (41) from two buffalo bulls of 4 to 6 years weighing 500 to 750 kgs reared at semen production centre, Department of Veterinary Gynaecology and Obstetrics, Pantnagar India, were used. Semen was collected twice a week through AV method for 6 months. The temperature and relative humidity of respective days was taken from meteorological department located nearby. Three groups were formed on the basis of THI i.e. Group I (64 to 72, n=10), Group II (72 to 78, n=13) and group III (78 to 84, n=18). Data was analyzed by least square of mean analysis to assess the effect of THI on various semen quality parameters. THI had no significant effect on ejaculate volume and pH but it had a significant (P<0.05) effect on mass motility and progressive motility. The results of this study indicated that the mass motility and progressive motility of the semen is found highest at the THI value of 72-78 and lowest at the THI value of 78-84.
