The aim of this experiment was to evaluate the production parameters of fast-growing broiler chickens when incorporating sunflower extracted meal into the feed mixtures. A control diet (C) containing only soybean extracted meal was formulated, and an experimental diet that included an 8% proportion of sunflower extracted meal. A total of 64 male chicks of the Ross 308 hybrid were included in the trial. During the first two control weighings (days 7 and 14), no statistically significant differences in live weight were observed. However, from day 21 of fattening until its end (day 36), the control group achieved the highest average live weights. The assessment of carcass yield and major meat parts revealed no statistically significant differences between the groups, indicating that the use of alternative protein feeds does not negatively affect these parameters. Feed intake and feed conversion were not influenced at any stage of fattening. Statistically significant differences were found only in average daily gains, where the group receiving 8% sunflower extracted meal showed the lowest values both in the BR2 phase and over the entire fattening period. Overall, the results indicate that partial replacement of soybean extracted meal with sunflower extracted meal can be implemented without adverse effects on most of the evaluated production indicators in broilers.
