Rotavirus

Rotavirus is widespread but herd resistance is good thus outbreaks are not common. Scours generally start after 4 days of age and is less severe if they are older when they contract the virus. Diarrhoea is often associated with E. coli or coccidiosis. The scour is usually yellow-grey and pasty in the early stages, then become grey. Affected pigs can become scrawny and rough haired, but mortality is low.
