RESUMO:

Bovine neosporosis is a parasitic disease caused by the protozoan Neospora caninum. The parasite has a worldwide distribution and mainly affects the dairy cattle herd, however, reported in beef cattle, being described as one of the main causes of abortion in cattle. It is of great relevance in cattle breeding, since the presence of the etiological agent is associated with bovine abortion in the world, thus promoting direct and indirect economic losses. It can cause early embryonic death, fetal abortion or mummification, stillbirths and neonates with neurological symptomatology. This study was developed in the Dairy Cattle Sector of the UFRRJ, located in the city of Seropédica-RJ, where blood samples were collected from 40 dairy cows in the reproductive phase of the cranial surface epigastric vein, and the samples were tested by indirect immunofluorescence (RIFI) for detection of anti-N antibodies. caninum. The serology was performed at the Laboratory of Coccidia and Coccidiosis (LCC) of UFRRJ. From the serological results, we verified the association or not with the manifestation of reproductive disorders, analyzed through the collection of data from the records of reproductive history from 2017 to 2018 and observations of the herd in the course of the study. The Chi-square test was used as a statistical model to verify the existence of an association between serology and reproductive disorders, adopting a confidence level of 95%. The results of the study show a seroprevalence in the herd of 27% (11/40) for N. caninum, however, after statistical analysis the association between seropositivity and reproductive disturbances in the evaluated herd was not confirmed. These results allow us to infer that even if the parasite is present in the studied herd, it did not appear to be responsible for the reproductive alterations found.
