The aim of this study was to determine the fatty acid profile in 4 types of fat deposits in Polish Holstein-Friesian (PHF) and Limousine × Polish Holstein-Friesian (LM × PHF) bulls. The experimental materials included samples of intramuscular, intermuscular, subcutaneous, and internal fat collected from the carcasses of 28 PHF bulls and 26 LM × PHF bulls. Determined fatty acids (FAs) were divided into saturated (SFAs) and unsaturated (UFAs) FAs, including monounsaturated (MUFAs) and polyunsaturated (PUFAs) FAs. The UFA/SFA, MUFA/SFA, PUFA/SFA, and PUFA n-6/PUFA n-3 ratios were calculated. Internal fat was characterized by the highest SFA concentrations, and subcutaneous fat had the highest MUFA content. Intramuscular fat was marked by a high proportion of PUFA and the highest PUFA/SFA ratio. The subcutaneous fat of PHF bulls had the highest n-6/n-3 PUFA ratio.
