Conception Rate (CR) plays a major role to achieve a successful dairy farm. The present study was aimed to observe the conception rate of dairy cattle following artificial insemination (AI) in Sirajgonj district of Bangladesh. A total of 543 non descriptive indigenous and 317 crossbred cows were collected through face to face questionnaires with the farmers considering the breed, age, parity, retention of placenta, insemination after onset of estrous, calving interval and days open as potential risk factors affecting CR of cows. The collected data were analyzed by using SPSS software. The mean conception rate was 72 percent following AI. Cross breed cows (co-eff.= -0.003, p<0.05), removal of placenta >6 hours (co-eff. = -0.17, p<0.05), days open (co-eff.= -.001, p<0.01) were identified as the risk factors for low CR after AI. Age of cow <2.5 years (co-eff.= 0.005, p>0.005), parity>5, (co-eff. = 0.210, p>0.05), Insemination after onset of estrous <3 hours (co-eff. = 0.008, p>0.05), calving interval >551(co-eff.= 0.00, p>0.05) were associated with the risk for lower CR following AI. Therefore, it could be stated that conception rate depends on various factors.
