Vaccination for Bovine Respiratory Syncytial Virus

Benefits for both Cow /Calf Herds and Feed lot Cattle

Abstract

The bovine respiratory syncytial virus (BRSV) belongs to the genus Pneumovirus within the family Paramyxoviridae. Although isolation of the virus from sick cattle has proven to be very difficult, serologic studies have shown that 60-80% of cattle in the United States have anitbodies to BRSV.¹ Along with the increasing awareness of the presence of the virus, BRSV has recently been implicated as an important primary pathogen in the development of respiratory disease in dairy cattle, cow/calf herds, and in feedlot cattle.^1-7
