Nationwide survey of antibodies to bovine coronavirus in bulk milk from Swedish dairy herdsNationwide survey of antibodies to bovine coronavirus in bulk milk from Swedish dairy herds
Bulk milk samples from 2236 dairy herds randomly selected throughout Sweden in proportion to region and herd size were analysed for antibodies to bovine coronavirus (BCV) in an ELISA. The results were expressed as optical density (OD) values and an OD>0.04 was considered positive. Eighty‐nine per...
