Abstract: The present study was conducted with an aim to access the incidence of peri-parturient reproductive disorders and to determine the seasonal calving pattern in cross bred cows of Jammu region. A total of 2638 calving records of cross bred dairy cows between 2010 – 2016 were screened retrospectively for peri-parturient reproductive disorders. The most common reproductive problems recorded in the present study were retained placenta (13.34%), still birth (6.36%), abortions (5.68%) and dystocia (2.19%). Incidence of retained placenta, still birth and dystocia were higher in winter season than in rainy and summer season. Whereas the incidence of abortion was higher in rainy season.
