Neonatal diarrhea remains an important cause of illness and death of beef calves. Costs of the disease include loss of performance, mortality and the expense of medication and labor to treat sick calves. In addition, cattle producers often become disheartened after investing long hours to treat scouring calves during an already exhausting calving season. Our objective was to design and test calving systems that would reduce morbidity and mortality due to neonatal calf diarrhea.
