Data from 19644 cows were collected and analyzed to determine effect of parity and season on the occurrence of various reproductive disorders in dairy cows. A total of 1251 cases of reproductive disorders were recorded making an overall occurrence of 6.36 per cent over a 6 year period. The relative occurrence of endometritis was 80.65 per cent followed by cystic ovaries (9.18%), retained foetal membranes (4.65%), dystokia (2.79%), genital prolapse (1.87%) and abortion (0.87%).
