This study was carried out to determine the relationship between the method of manure removal and clinical mastitis, dystocia, retained placenta and repeated breeding, which are some of the main problems of cattle rearing. 709 cows that were examined, were housed in 37 dairy herds and for each cow the following data were collected: dystocia (yes/no), retained placenta (yes/no), clinical mastitis (yes/no) and repeated breeding (yes/no). 594 cows (84%) were housed in the herds in which manure was removed manually, while the others had automatic manure scrapers. From the results, it was seen that prevalence of mastitis, dystocia and repeated breeding were dependent on the method of manure removal.
