In many regions in the world the reduction in population sizes of native pigs is a conservation concern (Li et al. 2000; Martinez et al. 2001). However, in Australia, feral (or wild) pigs are a significant invasive species, and there are upwards of 10 million feral pigs present, inhabiting over 40% of the continent (Choquenot et al. 1996). Coupled with these large numbers and advances made in marker technology, there is an increasing awareness of the value in quantifying (and understanding) the biodiversity retained in non-commercial livestock breeds (e.g. Hall and Bradley, 1995). Well-characterized microsatellite markers, such as those recommended by the Food and Agriculture Organization and International Society for Animal Genetics (FAO-ISAG), are ideal for such studies. There is an increasing amount of data being generated from indigenous pigs, including Asian (Li et al. 2000; Kaul et al. 2001), American (Lemus-Flores et al. 2001) and wild European (Laval et al. 2000; Martinez et al. 2000; Vernesi et al. 2003) breeds. However, there is no such information available on the diversity of wild pigs in Australia or Papua New Guinea. Overall, the preliminary findings suggest that Australian feral pigs are genetically diverse, with heterozygosity and allelic diversity at 0.758 and 11.0 alleles per locus on average, respectively.
