Histological characteristics of the musculus longissimus lumborum et thoracis muscle fibres in pigs in relation to selected RYR1, MYOG, MYOD1 and MYF6 genotypes

Original language description

Histochemical and biochemical muscle fibre properties are the factors that influence the quantitative and qualitative characteristics of pork meat. The aim of the study was to assess the influence of genetic effects of selected genetic markers MyoD genesand RYR1 on the achieved indicators of muscle fibres in the musculus longissimus lumborum et thoracis (MLLT). The study included a total number of 216 hybrid pigs with the mean slaughter weight of 123 kg. Gene polymorphism was determined by the PCR-RFLPmethod. The gene polymorphism was determined in the RYR1, MYOD1, MYOG, and MYF6 genes. Muscle fibre types from MLLT were identified. Concerning the RYR1 gene, the study found that homozygous-dominant animals reached a lower number of type I (8.35 vs. 10.52; P<0.05) and a higher number of IIA (3.66 vs. 2.10; P<0.05) and a higher number of IIB (76.61 vs. 67.91; P<0.05). The maximum number in all types of muscle fibres reached BB genotype of the MYOG gene (type I: 14.02; IIA: 18.47; IIB: 8
