The effects of different nutrient composition in the feed on the muscle fibers typology in pigs
Original language description
The study deals with the effects of different levels of crude protein in the feed on the muscle fibers typology in pigs. The test included 72 hybrid animals (barrows and gilts) of the Dx(LWDxL) genotype. The pigs were fattened ad-libitum in three feedingphases. All animals were divided into 3 groups according to the crude protein (CP) level intake. In order to monitor the quantitative (number) and qualitative (area, diameter) parameters of the muscle fibers, there were muscle samples taken from the musculus longissimus lumborum et thoracis (MLLT) muscle following the animals' slaughter. The study showed that pigs with the highest amount of rapeseed meal level in their diet showed the smallest (P<0.01) slow oxidative muscle I type fibers area (2 292 ?m2). Furthermore, the highest (P<0.001) percentage of the type I muscle fibers (16 %) and their number/1 mm2 (31.0) were observed in the same group. The results show that different crude protein levels in the pig diet can affect their musc
