The insulin-like growth factor 2 gene (IGF2) has been described in several studies as a candidate gene for meat efficiency in pigs. IGF2 is a member of the growth factors family and has an effect on development of muscle tissue. The effect of IGF2 gene polymorphism on meat efficiency was analysed in a population of 121 Large White pigs. A PCR-based test and RFLP methods were used for detection of genotypes. Allele A, lacking the restriction site, was characterised by the presence of a 0.9-kb fragment. In allele B, the amplimer was cut into a 0.8-kb fragment and some barely detectable fragments. The statistical analysis was carried out according to the General Linear Model procedure. The genotype frequencies observed were: 1.65%, 33.88%, 64.46% for AA, AB and BB genotypes, respectively. There was a significant difference (P 0.05) between the AB and BB genotypes in live weight before the test. A significant association between AB and BB genotypes and body weight before the test was found. No significant difference in other traits of growth and meat efficiency was observed (P > 0.05).
