ResumoA cross-sectional study was conducted to determine the prevalence of infection with Neospora caninum and its association with risk factors in cattle farms located in the Bolivar municipality of Yaracuy State. A total of 408 cows and 142 heifers were evaluated from 51 farms randomly selected to determine the presence of antibodies against N. caninum using the indirect ELISA technique. By odds ratio (OR) was assessed the association of parasite prevalence with risk factors intrinsic and extrinsic to the animals. There was obtained a prevalence of 17,09% for animal and an infection rate of 74,51% for farm. The prevalence was significantly associated (P <0,05) with aptitude for milk production (OR = 3,01), the racial pattern Bos taurus (OR = 4,29), the fact that the animal was born on-farm (OR = 2,09), consumption of balanced commercial feed (OR = 1,82) and density greater than 3 cattle / ha (OR = 1,91). It was also found a negative association with the racial pattern B. indicus (OR = 0,48) and the size of the herd increased to 1.000 animals (OR = 0,33). No significant association was
