Abstract
In an inbred pig family founded by commercial breeds, nine microsatellite m arkers from porcine chromosome 4 were screened to find associations with we ight gain and fat deposition traits. In this family showing a linear decrea se in weight gain with inbreeding, an association (P < 0.05) was found betw een average daily slaughter gain and markers S0214 and S0373 located at app roximately 88 and 98 cM in the linkage map constructed in this study, No as sociation (P > 0.05) between backfat thickness and marker genotypes could b e detected. Furthermore, the genotypes of the markers showed a surprisingly high degree of heterozygosity in all of the inbred generations, even thoug h the theoretical inbreeding coefficients reaching 0.59.
