Effect of different dietary fats on the content of fatty
acids in the the blood serum and in the  longissimus
dorsi  muscle of rats

Forty eight rats divided into 6 groups were fed semi-purified mixtures with different kind of fats (6%); C - control group, T - tallow, L - lard, RO - rape seed oil, LO - linseed oil, FO - fish oil.The percentage content of fatty acids in the serum and in the longissimus dorsi muscle (l.d.m.) of rats was measured. The dietary fat did not influence the percentage content of saturated fatty acids (SFA) in the rat's serum. Increasing the percentage content of polyunsaturated fatty acids (PUFA) in serum and muscle at the expense of monounsaturated fatty acids (MUFA) was observed in rats receiving linseed oil. Feeding linseed oil and fish oil increased the content of PUFA_n-3 in serum and muscle. In contrast with serum, in the l.d.m. of rats a negative correlation between PUFA_n-3 and _n-6 was not found.
