The influence of this mutation on meatiness has been confirmed by other authors in various populations of pigs (Estelle et al. 2005). However, associations between the IGF2 muta- tion and growth performance and meat quality traits are not clear to date. Moreover, to date, there is no data about the influence of IGF2 on intra- muscular fat – an important trait determining the palatability of meat. The aim of our study was to compare body composition, growth performance,
and meat quality traits in Polish Landrace and Large White pigs, carrying opposite genotypes (A/A and G/G) in theIGF2 gene.
