The changes of fatty acids composition in beef of charolaise bulls slaughtered at different weight

Popis výsledku v původním jazyce

The aim of this work was to evaluate a slaughter weight influence (500--580; 581--640; 641--700 kg) of Charolaise bulls on intramuscular fat content and fatty acid profile in musculus longissimus thoracis (MLT). The beef samples from 144 bulls were usedto be evaluated. Statistically evidential (P < 0.05) differences in the intramuscular fat proportions (1.14 < 1.54 < 1.76%) in MLT samples were proved at all the weight categories of bulls. The highest average proportional ratio was determined in palmitic acid (C16:0), that ranged from 23.75% in bulls at 500--580 kg weight category to 24.79 % at 641--700 kg weight group. The lowest ratio of MUFA was in eicosapentaeonic acid (C20:1), its content ranged from 0.36% in the third weight group to 0.53% in 500--580 kg weight group. The highest MUFA ratio was in oleic acid (C18:1) at amount of 39.64% with difference +- 2.932%. The oleic acid ratio in beef rose up linearly according to the higher slaughtering weight (P < 0.01). Positive relation
