摘要:
Methods for protecting porcine fetuses from infection with Porcine Reproductive and Respiratory Syndrome Virus (PRRSV). The methods comprise breeding a female porcine animal with a male porcine animal. The female porcine animal comprises modified chromosomal sequences in both alleles of its CD163 gene, wherein the modified chromosomal sequences reduce the susceptibility of the female porcine animal to infection by PRRSV, as compared to the susceptibility to infection by PRRSV of a female porcine animal that does not comprise any modified chromosomal sequences in the alleles of its CD163 gene. The male porcine animal comprises at least one wild-type CD163 allele.
