There are five major infectious causes of diarrhea in calves less than 21 days of age. These include E. coli K99, rotavirus, coronavirus, Cryptosporidia, and Salmonella species. Noninfectious factors such as insufficient or poor-quality colostrum, poor sanitation, stress and cold weather can also cause or contribute to neonatal calf diarrhea.
