Preventing disease transmission through the transfer of in-vivo- derived bovine embryos

Investigation and experience have demonstrated that movement of in-vivo-derived bovine embryos can be accomplished while effectively limiting spread of infectious disease between populations of cattle. Experimental and theoretical justifications of current strategies for production of specific-pathogen-free, in-vivo-derived embryos are reviewed. Hazards of spreading bovine viral diarrhea virus via in-vivo-derived embryos are dealt with specifically. It is concluded that established sanitary procedures for producing pathogen-free, in-vivo-derived embryos are efficacious if the ethical and technical excellence of those performing the procedures can be assured.  2000 Elsevier Science B.V.
