Sažetak
This paper investigates the possibilities of enrichment of meat with PUFA n-3, especially with EPA and DHA. For this purpose 225 Ross 208 male broilers were divided into 5 groups, each consisting of 45 broilers. From 1st to 21st day of the fattening period broilers were fed with standard diets that contained 22.67% of crude proteins and 14.19 MJ/kg ME. From 22nd to 42nd day broilers were fed with finisher diets, balanced at the 20.43% of crude proteins and 14.18 MJ/kg. The first group was given F1 diets, which, besides other feedstuffs contained 5% of poultry fat ; 2nd, 3rd, 4th and 5th group were fed with F2, F3, F4, and F5 diets, which were added marine oil Pronova Biocare Epax 3000 TG in the amount of 0.5%, 1%, 1.5% and 2% respectively. The obtained research results showed that PUFA n-6 were enhanced from 6% to 11.46% in the lipids of breast muscles, and from 3.71% to 10.44% in the lipids of thigh muscles. PUFA n-6 / PUFA n-3 ratio was lowered from 2.95 to 1.22 in the breast muscles, and 5.35 to 1.60 in the thigh muscles.
