Antibodies to the historic RVC Cowden strain are transferred less efficiently across gut-mammary axis. Genotype specific VLPs (Cowden G1, RV0104 G3 and RV0143 G6 were used to coat immunoplates. Serum (A) and milk (B) from sows/gilts in Table 1 supplemental (fourfold serial dilutions 1:400, 1:1600, 1:6400 and 1:25 600) were tested for RVC IgA Ab titers.
