Abstract
Genes encoding retinol binding protein 4 (RBP4), follicle stimulating hormone subunit beta (FSHB) and epidermal growth factor (EGF) have been proposed as candidate genes for reproduction traits in pigs. The study presented in this paper aimed to find associations between variants of these genes and reproduction traits in pigs reared in Poland. Investigation included Polish Large White x Polish Landrace (n=288) and Yorkshire (n=195) sows. Individual genotypes were determined by means of PCR-RFLP (single nucleotide polymorphism in RBP4, FSHB) or PCR (insertion/deletion in EGF) methods. Obtained result showed that RBP4 variants were related to total number born (TNB) and number born alive (NBA) in 1st, 2nd and 5th parities, FSHB to TNB and NBA in first two parities, however EGF with both traits in all parities (P≤0.05 or P≤0.01). In case of RBP4 gene, heterozygous genotype (AB) was favorable for analyzed traits, however in case of FSHB and EGF homozygous genotype, AA and BB respectively. Obtained results indicate that polymorphism in three analyzed genes is associated with important reproductive traits of pigs kept in Poland.
