Short summary
The aim of this study was to investigate the polymorphism in the IGF-I gene and its associations with growth, body size, carcass and meat quality traits in Coloured Polish Merino sheep. The IGF-I genotype was found to have an effect on fore shank weight, kidney fat class and EUROP fat class, external fatness on carcass class, drip loss, and subjective assessment of meat colour. The IGF-I gene could be considered as a candidate gene of selected carcass and meat quality traits in sheep.
