Abstract
Microsatellite FSHBMS polymorphism at the 5’ flanking region of <I>FSHB</I> gene was genotyped and associations with reproductive traits in several pig populations and with reproductive tract components in the Large White × Meishan F<sub>2</sub> offspring were studied. The results showed that FSHBMS allele 98 carriers had a non-significantly higher total number born and number born alive in multiple parities; 118/118 animals had a significantly higher number of piglets at weaning than 98/98 and 98/118 animals (<I>P</I> < 0.05) and significantly higher litter weight at weaning and individual weight at weaning than 98/98 animals (<I>P</I> < 0.05). The 98/118 animals had the shortest gestation length (<I>P</I> < 0.05); the length of uterine horns and the length of oviducts of 98/98 individuals were shorter and longer, respectively, than those with 98/118 genotype (<I>P</I> < 0.05).
