Resumo: 	ABSTRACT Vegetable oils (VO) and animal fats are conventional lipid sources used in feed formulations. Frying fats (FF) and calcium soaps of palm oil (CaSPO) are low-cost lipid sources. This study evaluated the productive performance of broiler chickens fed diets with CaSPO in substitution for VO or FF. Two hundred, 1-day old male broiler chickens were allocated in a randomized design with factorial arrangement (22). Diets included 2 lipid sources (FF and VO) and 2 CaSPO levels (0 and 50%). The study had two phases (starter and finisher) of 21 days each. For the starter phase there was no effect (p&gt;0.05) of dietary treatments on the chickens’ productive performance. For the finisher phase birds fed diets with FF had higher feed intake and feed conversion ratio (main effect; p&lt;0.01) than those fed diets with VO. Over the 42-day feeding period animals fed FF had higher feed conversion ratio (main effect; p=0.02) and tended (p=0.08) to show higher feed intake than those fed diets with VO. The CaSPO substitution for VO or FF had no effect (p&gt;0.05) on the productive performance of broiler chickens. There was no influence of treatment on carcass yield. The drumsticks plus thighs were higher (main effect; p&lt;0.01) in birds receiving VO than in those receiving FF. The interaction (fat source*CaSPO) was not significant (p&gt;0.05). These results may indicate that VO is superior to FF and CaSPO may substitute for VO or FF without affecting productive performance of broiler chickens. Lipid source showed small influence on carcass characteristics.
