Özet: This study examined the effect of different oil sources use on the growth performance blood serum lipid profile of broilers. In the experiment, a total of 640 1-day-old unsexed broiler chicks were used. The dietary treatments were sunflower oil (SO), canola oil (CO), tallow (T) and the mixture of these oils in equal proportions. Thus, chicks were randomly distributed four dietary treatments with eight replications each has 20 chicks. The oil sources were supplemented to corn-soybean meal based starter (1 to 21 d; % 23 CP, 3000 kcal ME/kg) and finishing feeds (22 to 42 d; % 20 CP, 3200 ckal ME/kg) at inclusions levels of 5% and 7.5%, respectively. During the six-week trial, feed and water were given as ad libitum. As a result of the experiment, the use of different fat sources in broiler feed has no significant effect on body weight gain (P>0.05). The feed intake and feed conversion ratio of the chickens fed with sunflower oil supplement was similar to the chickens fed with canola oil supplemented feed, and significantly lower than the chickens fed with feedstuff and mixed oil supplement (P<0.05). The addition of different fat sources to broiler feeds had no significant effect on serum triglyceride, total cholesterol, HDL and LDL concentrations (P>0.05). However, the total cholesterol, HDL and LDL concentrations of male broilers were higher than the female broilers (P<0.05). It is concluded that the use of sunflower oil in broiler diets improves performance over other fat sources without no significant effect on serum lipid profile. It is data from the present experiment also suggest to use animal fats in mixtures with oils to increase their metabolizibility rather than theirs single use in the fed.
