Neospora caninum is one of the most common, and most overlooked, causes of abortion in beef and dairy herds. This parasite spreads through infected dogs, foxes, or coyotes and can pass from dam to calf during pregnancy, often going unnoticed until it costs you pregnancies and profitability.
Testing is the only effective way to manage Neospora in your herd. A simple blood or serum test can identify carriers so you can make informed breeding and culling decisions. By identifying and managing carriers early, producers can break the cycle of infection and protect future calf crops.
