Visfatin encoded by the NAMPT gene (nicotinamide phosphoribosyltransferase, formerly also known as PBEF – pre-B cell colony-enhancing factor) is suggested to play a role in lipid metabolism and pathophysiology of diabetes mellitus type 2. A new microsatellite SCZ004 was detected within intron 9 of the NAMPT gene. In Czech Large White (n = 95) frequencies of alleles 282, 286, 287, 299, and 304 were 0.02, 0.39, 0.07, 0.04, and 0.48, respectively. Allele 286 was predominant also in Landrace (n = 11) and Black Pied Prestice (n = 11) breeds. Association analysis was carried out between previously reported SNP AM999341:g.669T>C in intron 9 of the NAMPT gene and backfat thickness, average daily gain and lean meat content in Czech Large White (n = 215), Black Pied Prestice (n = 96) and Landrace (n = 105). The CC genotype was associated with higher backfat thickness (CC was associated with lower backfat thickness when compared to TT and CT genotypes (CC genotype was associated with higher lean meat content when compared to CT (not significant) and TT genotype (CC had the lowest lean meat content when compared to CT and TT genotypes but only the difference between CC and CTT was statistically significant (Keywords:visfatin; NAMPT; PBEF; SNP; microsatellite; pig; association analysis
