Description
  • The aim of this work was to evaluate a slaughter weight influence (500--620 and 630--740 kg) of Charolaise bulls on fatty acid profile in musculus longissimus thoracis (MLT). The bulls were slaughtered at the age of 485--569 days. The average weight gain during fattening was 664 +- 91 g per day. The carcasses (weight ranged from 300 to 395 kg) were classified to the class of meatiness %22U%22 and %22R%22 and the class of fattiness %222%22. The beef samples (n=83) were excised from carcass at the half cutting level between 8th and 9th rib and analyzed. The highest average proportional ratio was determined in C16:0 that ranged from 22.804 % in bulls at 500--620 kg weight category to 24.797 % at 630--740 kg weight group. The lowest ratio of MUFA was in eicosapentaeonic acid, its content ranged from 0.234 % at the second weight group to 0.587 % at 500--620 kg weight group. The highest MUFA ratio was at C18:1 at amount of 38.857 % with difference +- 2.373 %. The oleic acid ratio in beef rose up linearly according to the higher slaughtering weight (P < 0.01). Positive relation was proved between a slaughter weight and C18:3; C20:5 and C22:5 PUFA content. The decrease of eicosapentaeonic and eicosadienoic acid was negative fact due to the essentiality for human health.
