  1. The calves were exposed to BCoV in the field (F1-6), were exposed to F-animals (E1-4) or exposed to E-animals (S1-2). aPeak rectal temperature (rt) bRunny to watery stools were considered diarrheic. c Mucopurulent or purulent nasal discharge (nasal discharge score =2). d Five days of i.m. treatment with 30 000 IU procaine benzylpenicillin was initiated on indicated day. e Calf F3 was treated for six days
