Percent contents of particular fatty acids and total cholesterol content were determined in intramuscular fat in m. longissimus thoracis and in m. semimembranosus in a trial on 10 cows of the Black-Pied Lowland breed with preslaughter live weight of 510-550 kg. Fat nonsaturation index was calculated as the ratio of unsaturated to saturated fatty acid contents, while fat nutritive value index was calculated as the ratio of essential fatty acids to saturated fatty acids. The percentage of saturated fatty acids in m. longissimus thoracis was 49.86 % and 47.45 % in m. semimembranosus. There were not any significant differences between the muscles in total cholesterol content (73.88 and/or 72.77 mg/100g). The content of total intramuscular fat in m. longissimus thoracis (3.90 g/100 g) was found to be higher than in m. semimembranosus (1.98 g/100 g).
