The aim of this study is to find the influence of utilization of these kinds of fats and their mixing with different levels on broilers some parameters of production performance. In this work we investigated the effect of three types of fat in the diet of broiler (Ross-308) chickens on performance properties. One-day 800 chickens were divided into four testing groups: C (5% packed fat), T1 (2.5% packed fat +2.5% sunflower oil), T2 (2.5% packed fat+2.5% rapeseed), T3 (2.5% packed fat +1.25 rapeseed +1.25% sunflower oil). There were insignificant differences (P gt 0.05) for live weight (LW) and daily weight gain (DWG) at all periods of breeding and both sexes except finisher period for male where there were significant differences (P less than 0.05). The highest value for LW was obtained in C group for males 3.027 kg and 2.522 kg for females. The highest DWG was achieved in group C for males; and for females all tested groups were lower than for males. Insignificant differences (P gt 0.05) were documented for feed intake (Fl). All tested groups consumed less feed than C group. There were significant differences (P gt 0.05) for feed conversion ratio (FCR) at all periods of breeding and for both sex except finisher period for female where there were significant differences (P less than 0.05). For production index (PI), there were significant differences (P less than 0.05) among all treatments in both sexes.
