Description:	The aim of this study was to describe the epidemiology of infectious bovine rhinotracheitis (IBR), bovine viral diarrhea (BVD), neosporosis (NEO) and leptospirosis (LEP) from the perspective of the impact these diseases have to cause reproductive problems in dairy cattle herds located in different mesoregions of Rio Grande do Sul State. The herds analysed belong to two cooperatives and an association of producers. The seroprevalences of IBR, BVD, NEO and LEP ranged from 54.4 to 60.3%, 30.0 to 42.5%, 21.8 to 35.0% and 15.8 to 27.5%, respectively. The seroprevalences of IBR show a homogeneous distribution of the disease according to the mesoregions. Nevertheless, IBR was associated with estrus recurrence and abortion in herds located in the northeast and northwest mesoregions. BVD was associated with rearing of estrus in herds located in the southeast, southwest, northeast and northwest mesoregions. NEO was associated with cases of abortion in the herds located in the northeast and northwest mesoregions. LEP was associated with miscarriages in herds located in the northwest mesoregion. It was found that the epidemiological character of the disease cases were distinct in the different mesoregions. In this way, the priorities in the control and prevention programs of these diseases are different between the mesoregions, cooperatives and association of producers. Despite that fact, common control procedures were found amongst the disease cases studied; each one of them has its peculiarity in relation to the epidemiology and consequently control and prevention
