Producers understand neonatal calf diarrhea is a problem on their farms. National Animal Health Monitoring System data from 2007 reported an average calf mortality of 8% annually, with scours as the leading cause of death in unweaned calves at 56.5%.

Most causes of scours are preventable. However, the infectious causes of neonatal diarrhea are typically bacteria, viruses or protozoa. Other noninfectious causes that may contribute to neonatal diarrhea are:

■ poor-quality colostrum

■ poor sanitation

■ stress

■ inadequate ventilation

■ adverse weather conditions
