Association of BF gene polymorphism with litter size in a commercial pig cross population

Abstract In the present study, the single nucleotide polymorphism of CFB (Complement Factor B), BF gene, was analyzed by PCR-RFLP in a commercial pig population in Greece. BF gene is coding for properdin, a protein that plays an integral role in the uterine epithelium growth and is found in a QTL region with many other genes associated with specific reproductive traits. BF gene is considered to affect various reproductive traits in pigs and the present study associated the BF gene genotypes with litter size of the sows (TNB, total number born and NBA number born alive piglets/birth). Sows with AB genotype gave statistically significant lower values for TNB and NBA piglets/birth ( p
