These indicators were determined in a trial on three breeds of slaughter bulls (Slovak Pied, Slovak Pinzgau and Black-pied Lowland) at average pre-slaughter weight of 501 to 545 kg: fatty acid spectrum, cholesterol content, as well as the ratio of the contents of unsaturated to saturated fatty acids and the index of fat nutritive value, which describes the ratio of essential fatty acids to saturated fatty acids. There were no significant differences between the breeds besides three, less important fatty acids with minimum concentrations. As for the calculated indexes, the values of fat unsaturation index (I1) ranged from 1.02 to 1.06 and those of fat nutr4itive value index ranged from 0.07 to 0.08. The determined average cholesterol content was 65.34 to 71.11 mg/100 g. Average content of saturated fatty acids ranged from 48.60 to 50.28 % and that of unsaturated fatty acids from 49.42 to 51.42 %.
