Objectives of this research were to evaluate association of polymorphisms in the ADIPOQ and FSHR genes and weaning-to-first service interval (WSI), number of piglets born alive (NBA), total litter birth weight (LBW), number of piglets at weaning (NPW) and total litter weaning weight (LWW) in a commercial swine population composed of Landrace (L), Large White (W), L x W and W x L sows in northern Thailand. The dataset consisted of 470 records for WSI, NBA, and LBW, and 330 records for NPW and LWW from 363 sows. Blood samples were also collected from these 363 sows. One SNP and 2 alleles were studied for the ADIPOQ (G and A) and FSHR (C and T) genes. The SNP for ADIPOQ was AJ849536: g.1716G GT A and the SNP for FSHR was SNP as AF025377: g.1166C GT T. Associations between traits and alleles, and traits and genotypes were performed using linear models. Allelic effects were modeled as regressions of traits on numbers of G alleles for ADIPOQ and numbers of T alleles for FSHR. Neither allelic nor genotypic effects were significant for either the ADIPOQ or the FSHR gene. Low numbers of animals, tropical environmental conditions and genetic similarity among animals due to intra-herd replacement of boars and gilts during the period of the study may have contributed to the lack of significant differences among allelic and genotypic effects in this population. Thus, the ADIPOQ and FSHR genes will be of little help for selecting pigs in this population.
