Abstract

In this attempt the relaxation times using 1H-NMR spectroscopy from three different (subcutaneous, perinephric and internal fat) fat depots of Hungarian Grey and Holstein Friesian extensive or intensive fattened young bulls were measured. The relaxation properties were compared with the analysis of fatty acid compostion. The different diets and the sample location have a higher influence on the relaxation times than the breed. In fat samples from extensive groups the T1-relaxation time was longer, while the T 2-relaxation time was significantly shorter in intensive fed groups. The T2-relaxation time, as well as the relaxation time of T 21,-und T22-components were the shortest in extensive fed animals, while the proportion of T21-component was the highest in kidney fat, furthermore the difference was statistics proved. The T 2-relaxation time showed a close negative relationship with the ratio of saturated fatty acids (SFA). The ratio of v21 and v22 depends on chemical composition of fat samples. In fat tissues with a high SFA percentage caused a higher proportion of v21. It is suggested that differences in fatty acid compositon of fat samples caused also alteration in the relaxation time.
