ABSTRACT

FSHB gene is considered as a marker for reproductive traits in human as well as in domestic animals. The aim of this study was to estimate associations between polymorphism in FSHB gene and reproductive traits in Polish Landrace breed (n=260) and Polish Large White × Polish Landrace crossbreed (n=381) sows. The following traits were analyzed: total number of piglets born (TNB), number of piglets born alive (NBA) and number of piglets weaned (NW). The polymorphism in FSHB gene was determined by PCR-RFLP method using HaeIII restriction enzymes. Mixed linear model  was applied for association analysis which considered effects of genotype, litter order and year season. Two alleles of FSHB gene were identified – A and B with following frequency: 0.058 and 0.942 (Polish Landrace), 0.150 and 0.850 (Polish Large White × Polish Landrace) respectively. The distribution of genotypes was in Hardy-Weinberg equilibrium in both of analyzed herds. Analysis of relationship between FSHB/HaeIII polymorphism and reproductive traits in sows showed that genotype BB was favorable for all analyzed traits in first and second parity but differences were small and not confirmed statistically. The significant effect (P≤0,01) of litter order on analyzed traits was however observed.

Key words: FSHB gene, pigs, polymorphism, reproductive traits.
