The population of the present study was crossbred dairy cows in respective dairy farm. A observational survey method was applied in dairy farms up to their parturition period. Reproductive histories of the studied cows were assessed by direct interviewing and from record book of the owners and near by government veterinary hospital. At the beginning of the study, 317 cows were selected and registered and then follow up them in pre and postpartum period. All study animals were selected and identified by individual tag number/ID. Then all necessary information: breed, age, parity, date of service, date of calving , Estrous after last calving, conception rate, service per conception, milk production rate, managemental system, body condition score, reproductive complications before and after postpartum period. A regular visit of the farms was carried out to collect data on the major postpartum reproductive problems of dairy cows. Finally, parturient cows were grouped in to those giving birth without any problem and those giving birth with problems according to the following definitions.
