The present study was designed to evaluate the Pregnancy Diagnosis-Positive Rate (PD-PR) along with conception rate (CR) in an organised farm (Livestock Research Centre, National Dairy Research Institute, Karnal) to take effective management decision. One year record of Artificial Insemination (A.I.) and PD of dairy animals (N=1327; comprised 1003 cows and 324 buffaloes) was analysed. On an average, cows and buffaloes were presented for per rectal pregnancy diagnosis after 75.63 (38-119) and 76.3 (46-128) days, respectively of A.I. Overall PD-PR value of cattle was observed to be significantly higher compared to buffaloes (70.77 and 59.45%, respectively, prus symptoms as well as on CR.
