Abstract	Bovine neosporosis caused by Neospora caninum, contributes together with other infectious agents to undermine the reproductive effi ciency of cattle. In order to determine the seropositivity to N. caninum were processed 2542 samples from 124 farms dual purpose cattle, distributed in fi ve municipalities (Simon Planas, Urdaneta, Torres, Crespo and Jimenez) Lara state. Seropositivity was detected by indirect ELISA immunoassay. The seropositivity (SP) general was 17.23%. Simon Planas municipality presented a signifi cantly higher SP (26.11%) with respect to municipalities Crespo (9.88%), Torres (14.05%) and Urdaneta (14.39%), while Jimenez (20%) showed no statistical differences with the rest municipalities. In 91.94% of cattle farms were found positive for N. caninum, with ranges of SP ranging from 2.78 to 62.5%. Females showed a 17.69% of SP and males 13.39%, without signifi cant differences between groups. Nor were any differences of SP by age group, with 20% for yearling calves, 17.06% for adults, 15.52% for heifers and 12.5% for calves. This suggests that in the herds studied, Neospora caninum infections are predominantly transmitted transplacentally. These results help to broaden the epidemiological studies on the geographic distribution of bovine neosporosis in Venezuela, and suggest strategic measures of control to reduce the impact of neosporosis might have on the reproductive effi ciency of cattle herds.
