Abstract: Transmission of bovine leukosis virus (BLV) by embryo transfer was investigated in a large commercial Holstein herd. One hundred and sixteen calves, transplanted as embryos from BLV-positive cows into BLV-negative heifers, were serologically negative, as were recipients, whereas 5 of 29 (17%) calves transplanted as embryos into BLV-positive recipients were infected with BLV, as evidenced by antibodies in the agar gel immunodiffusion test.
