The present study was undertaken to establish the seasonal variations in semen biochemical indices in Bhadawari bull. Four fertile, healthy adult Bhadawari bulls aged between 2 to 4 years were used as semen donors. The study was conducted over a period of six months and divided into three seasons as winter season (February-March), dry summer season (April-May) and wet summer season (June-July). Sixteen semen samples were collected in each season (four ejaculates from each bull) by using Artificial Vagina and seminal plasma were harvested by centrifugation. The results of the study showed gradual and significant rise in values of ALT, AST, ALP, cholesterol and triglycerides and decline in values of amylase with increase in ambient temperature and THI. Amylase showed negative correlation and other indices showed positive correlation with ambient temperature and THI. The ambient temperature and THI showed positive correlation with biochemical attributes except amylase while humidity showed negative correlation. It could be concluded from the study that temperature and THI of season significantly affects the semen biochemical attributes of Bhadawari bulls.
