FILIPCIK RADEK, VOŘISKOVA JARMILA, DUFEK ALES, PAVLIK ALES, HOSEK MARTIN. 2015. Comparison of the Carcass and Beef Quality of the Czech Fleckvieh Bulls with Genotype TT and CT for Leptin and Bulls of Galloway and Charolais Breeds. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 63(1): 29–37. The objective of the present study was to compare the quality of the carcass and beef of bulls genotyped for leptin (TT and CT) of the Czech Fleckvieh cattle with Galloway and Charolais bulls. Analysed were 232 bulls. The quality of the carcass body was signifi cantly (p 0.05) aff ected by the breed. In terms of fatty acids signifi cant (p < 0.01) diff erences were discovered in the intramuscular fat of the MLT between the Czech Fleckvieh cattle and both beef breeds in the levels of C16:0; C20:0; C14:1; C16:1; C20:1; C20:2 and rate of the C14index. A signifi cant (p < 0.05) diff erence in the level of oleic acid was detected between the meat of the Czech Fleckvieh cattle (37.77 g.100g −1) and Charolais (41.23 g.100g−1). From the viewpoint of human health the most favourable rates of fatty acids (C14index = 22.07; C16index = 13.63; C18index = 64.19; AI = 0.67) were seen in the meat of the Czech Fleckvieh cattle. The smallest diameter of muscle fi bres (35.61 μm) was detected in the Czech Fleckvieh cattle as compared to the Galloway (37.60 μm) and Charolais (38.01 μm) breeds.
