Sažetak
This paper elaborates the effect of dietary supplementation of sunflower, rapeseed and linseed oils on the profile of fatty acids in breast muscle lipids. Fattening of the Ross 308 chickens lasted for 42 days. Chickens were divided into three groups. From the 1st to 21st day, chickens were fed starter diets that contained 22% of protein and 12.64 MJ/kg ME. From the 22nd to 42nd day feeding was continued with finisher diets that contained 20% of protein and 13.5 MJ/kg ME. The 1st group was given diets supplemented with 5% of sunflower oil, the 2nd group had diets with 5% of rapeseed oil, and the 3rd one was fed diets containing 5% of linseed oil.Based on the completed research into the vegetable oil supplementation to chickens’ diets (5% of sunflower oil in diets of the 1st group, 5% of rapeseed oil in diets of the 2nd group and 5% of linseed oil in diets of the 3rd group) and its effect on the profile of fatty acids in breast muscle lipids, it can be concluded that the 1st group had statistically significantly higher (P<0.001) content of SFA and PUFA n-6, and the 2nd group had higher content of MUFA. In comparison with the 1st and 2nd group, statistically significantly higher (P<0.001) content of PUFA n-3 (with the highest portion of α LNA) was determined in breast muscle lipids of the 3rd group. The ratio of PUFA n- 6/PUFA n-3 in breast muscle lipids was statistically significantly lower (P<0.001) in chickens fed diets supplemented with linseed oil (2.47) than in chickens fed diets with supplemented rapeseed oil and sunflower oil (6.52 : 10.87, respectively).
