Abstract:
Fixed-time artificial insemination method (FTAI) has been used in buffalo to improve reproductive efficiency and rate. Estrus intensity and duration vary significantly among individuals and are affected by many factor. Therefore, estrus identification technology plays an important role in reproduction management of dairy herds. Vaginal and vulvar temperature measurement are more reliable and realistic method to use for the purposes of regulating reproduction and managing production. Hence present study was designed to investigate the change in vaginal and vulvar temperature during estrus induction protocol on 193 buffaloes and buffalo heifers during summer and winter under farm and field conditions. Study concluded that average vaginal temperature on the day of estrus increased in both winter and summer seasons in both buffalo and buffalo heifers.
