The aim of the thesis named: "Evaluation of amino acid content in beef meat of Czech Fleckvieh bulls" was to evaluate the dependence of selected factors on the quality para-meters of beef, but primarily on the content of free amino acids. Amino acids are among the most important indicators of the nutritional quality of meat. The influence of slaughter age (520 - 540 days and 640 - 760 days) and the effect of carcass weight (220 - 300 kg, 301 - 350 kg and 351 - 500 kg) was analysed, both these indicators have a demonstrable effect on meat quality. In the case of essential free amino acid, the most represented was leucine, the amount of leucine was highest in animals in older and heavier weight categories. Furthermore, an effect of net gain (g.day-1) was observed, in this case the animals were categorized as follows: 437 - 550 g.day-1, 551 - 600 g.day-1 and 601 - 880 g.day-1 . Last factor whose effect was observed in relation to the quality of the meat was genotyping bulls in order to pro-ve the presence or absence of leptin genotype allele called "T".
