Abstract: The experiment was conducted between September and October 2014 in the Experimental Base of the Agriculture Institute – Stara Zagora with 150 male Ross 500 chickens divided into two groups: experimental and control. The sunflower oil in the ration of the experimental group was replaced by the feeding oil Rumanol ML. The latter was produced by the German company Rubelmann and includes five vegetable oils - coco, palm, shea, rape and sunflower at different proportions, with total linoleic value between 23- 25 %. The following parameters were determined: individual live weight – at hatching and at 10, 21, 35, 49 days of age. At the end of the trial, slaughter analysis of 3 male broiler chickens with body weight close to the group average was made, and after 12-hour fasting – 12 slaughter traits were determined. During all periods of growth and development, live body weight was statistically significantly higher in broilers whose diet was supplemented with Rumanol ML (p< 0.001). The addition of feeding oil Rumanol to poultry ration resulted in lower feed consumption per 1 kg weight gain by 6.8% and higher European Poultry efficiency factor than controls - by 18.16%. Absolute values of slaughter traits in 35-day-old broiler chickens were statistically significantly different (p<0.01). At 49 days of age, thigh and breast muscles, as well as grill weight of Rumanol-supplemented birds were by 20.7%, 15.5%, 11.41% respectively higher than controls,.
