A study was carried out to evaluate the effect of cashew apple in feed on the zootechnical performance of broiler chickens in the finished phase. It involved 180 broiler chicks, of the « HUBBAR » strain, distributed in 12 experimental units according to a completely randomized device comprising 4 treatments and 3 replicates each. It is a control feed (PC0) containing maize as the main source of energy and three experimental feeds containing respectively 15 % (PC15), 30 % (PC30) and 45 % (PC45) respectively of cashew apple. At the end of the finishing phase, it was observed that the growth performances of the animals fed with the feeds PC0, PC15 and PC30 are superior to the weights of those fed with feed PC45 (p <0.05). The feed consumption and feed conversion index are identical for the PC0, PC15 and PC30 treatments. However, they increase with 45 % inclusion. The feeds PC15 and PC30 had the lowest production costs per kilogram of live weight. Concerning the characteristics of the chickens’ carcass, cashew apple powder had no effect on the carcass yields of animals fed the different types of feed (p> 0.05). In the finishing growth phase, a 30 % inclusion rate of the cashew apple powder in the feed produces chicks with comparable zootechnical performance to a ration containing exclusively maize as the main energy source.
