Use caution when adding to herds
The Prairie Star
Beef producers purchasing cows or cowcalf pairs as herd additions should keep animal health considerations in mind. By far the most common way of introducing new diseases into a herd is through purchase of infected animals, said SDSU Extension Veterinarian Russ Daly.
Daly said many good-quality cattle are moving through sale barns as producers in drought-hit areas of South Dakota sell livestock. As a result, producers in less affected areas may look at picking up additional livestock to add to their herds. In addition, producers may find themselves temporarily taking in cattle from these areas.
