Summary Here, we report genotyping conditions for 434 new polymorphic pig microsatellite markers containing trinucleotide and tetranucleotide repeat motifs in pig. Microsatellite sequences were detected in silico from bacterial artificial chromosome (BAC) clone end sequences and mapped to the pig genome. A set of 22 microsatellites is described, which can be separated in a simultaneous electrophoresis by multiplexing across a large size range, in combination with 4‐colour labelling. Marker information content and false pedigree exclusion probabilities are documented in five purebred populations, allowing assessment of this panel in pig parentage testing applications. Combined exclusion probabilities >99.7% were achieved in all pedigree test cases.
