Nebraska innovation reduces calf scours and improves herd health outcomes
Cold spring mornings during the calving season can be difficult for ranchers, especially when calf health problems arise. About 25 years ago, a simple yet powerful solution was developed in Nebraska to address calf scours, a disease that once caused major losses in beef herds.
The Sandhills Calving System was created through a collaboration between a ranch family, a local veterinarian, and researchers from the University of Nebraska. Their goal was to find a practical way to reduce illness and death in newborn calves.
Instead of relying only on medicines, the team focused on improving management practices. The system works by separating calves based on age and regularly moving pregnant cows that have not yet calved to clean pastures. This reduces the risk of younger calves being exposed to harmful pathogens.
Research showed that calf scours are often caused by the buildup of common bacteria, viruses, and protozoa in the environment. As calving season continues, these pathogens increase, putting younger calves at higher risk. By controlling exposure, the system helps break this cycle.
Early results showed strong improvements. Many ranchers reported fewer illnesses, lower treatment costs, and in some cases, no calf deaths from scours. “When we first started trying it, we didn’t know if it would work,” said Mart McNutt at the McNutt Ranch west of Tryon. “But once you learn the basics of it, it’s just like turning the scours switch off.”
The system was developed without formal funding, showing the strength of teamwork between ranchers and veterinarians. Over time, it has been widely adopted across North America.
Today, the Sandhills Calving System remains an important example of how simple, science-based management changes can improve animal health. It continues to help ranchers raise stronger, healthier calves while reducing costs and stress during the calving season.
