Abstract

In the last 10 years Neospora caninum has been identified as a major cause of abortion in dairy cattle worldwide. The objectives of this study were to characterize the impact of N. caninum infection on production and health in Ontario Holstein dairy herds and to identify possible risk factors for N. caninum serostatus and related abortions.
