Abstract

Eleven yearling calves were vaccinated with BRSV
Vac® 41. Serum samples collected 35 days after vaccination were sent to 14 different diagnostic laboratories around the United States for assay of IBR, BVD and BRSV antibodies. A great deal of lab to lab variation was encountered. This variation was due in part to the virus strain used, lab technique and cell culture line utilized.
