The aim of this study was to compare muscle histochemical composition in m. longissimus lumborum between different crossbreed fatteners. The research was carried out on 36 fatteners from three different crossbreed (12 animals in each) as follows: group I (♀Duroc x Hampshire♂), group II (♀Polish Landrace x (Duroc x Hampshire)♂) and group III (♀(Polish Landrace x Polish Large White) x (Duroc x Hampshire)♂). For histochemical analysis of muscle fibre types the activity of dehydrogenase NADH2 (diaphorase) was detected using specific histochemical testes. The results of the current histochemical investigations showed that genotypes of fatteners can influence on histochemical composition of the muscle fibre types - especially on percentage and size of muscle fibre. These changes can have some influence on meat consumption quality.
