- Enterotoxigenic E. Coli (ETEC) is a major cause of neonatal calf diarrhoea in the first 4 days of life but rarely causes diarrhoea in older calves
- Salmonella tends to affect calves between 2 and 6 weeks of age and ranges in severity from mild disease to septicaemia and high mortality
- Rotavirus and coronavirus typically affect calves less than 3 weeks old with a peak incidence between 6 and 10 days of age
- Only 5% of calves infected with Eimeria species develop NCD but subclinical coccidiosis has a negative effect on feed conversion and growth
- Mixed infections of ETEC, C. parvum and rotavirus are common; biosecurity, rapid diagnostics and early intervention are key for control
