In an inbred pig family founded by commercial breeds, nine microsatellite markers from porcine chromosome 4 were screened to find associations with weight gain and fat deposition traits. In this family showing a linear decrease in weight gain with inbreeding, an association (P <0.05) was found between average daily slaughter gain and markers S0214 and S0373 located at approximately 88 and 98 cM in the linkage map constructed in this study. No association (P >0.05) between backfat thickness and marker genotypes could be detected. Furthermore, the genotypes of the markers showed a surprisingly high degree of heterozygosity in all of the inbred generations, even though the theoretical inbreeding coefficients reaching 0.59.
