Abstract:
1. A method for providing a pig whose genome is homozygous negative for at least two porcine endogenous retroviruses (PERV) loci selected from the group consisting of a G3 locus, a G19 locus, and a G28 locus, the method comprising: determining in a plurality of pigs whether their genomes are homozygous negative, homozygous positive or heterozygous for each of at least two PERV loci selected from the group consisting of a G3 locus, a G19 locus, and a G28 locus; selecting a first pig and a second pig from said plurality of pigs wherein the genome of said first pig is either homozygous negative or heterozygous for a first PERV locus selected from the group consisting of a G3 locus, a G19 locus, and a G28 locus and the genome of said second pig is either homozygous negative or heterozygous for a second PERV locus selected from the group consisting of a G3 locus, a G19 locus, and a G28 locus; and breeding said first pig and said second pig for one or more generations to produce a progeny whose genome is homozygous negative for both said first and said second PERV loci.
