Resumo: | The association between seropositivity for Neospora caninum and pregnancy rate in cows belonging to a surrogate herd submitted to embryo transfer technology was determined. The serological status was evaluated in 275 heifers, aging from 14 to 20-month-old. For N. caninum serology analysis of a monoclonal competitive ELISA test Kit was used, and 81 animals (29.5%) showed seropositive. Thus, two groups were randomly formed selecting 33 seropositive heifers and other 33 seronegative animals out of the remaining 194 animals. Seronegative animals were followed up by serological analysis until the end of the trial in order to identify persistently infected individuals. The pregnancy rate was 72.7% in the group of N. caninum-positive sera, and, 81.8% in the seronegative group.No significant difference was observed between groups according to Chi-square test. No association between N. caninum seropositivity and pregnancy rates in surrogate heifers was found. |
