In Côte d’Ivoire, protein feed in poultry farming is expensive. This study was conducted to develop new sources of vegetable protein (cashew cake) in the diet of pullets in the growth phase. For this, 216 ISA Brown pullets aged seven (7) weeks were selected and randomly distributed in four (4) compartments. These constituted batches were subjected to feed T0 (control, 0% cashew cake), T1 (100% cashew cake as the main source of vegetable protein), T2 (50% cashew cake) and T3 (95% cashew cake). Cashew cake-based feeds improved the zootechnical parameters but not significantly. In all batches, an increase in weight gain was observed ranging from 469.2g to 1325g. ADG varied from 8.51 ± 8.13 g/d (T1) to 12.90 ± 6.03 g/d (T0) while food intake (AI) varied from 2514.20 ± 388, 50g (T3) to 2969.87 ± 478.54g (T0). Also, the consumption index (CI) varied from 3.23 ± 0.60 (T3) to 3.43 ± 0.48 (T1). The incorporation of cashew cake in feed for growing pullets would be an alternative solution to reduce the cost of feed for laying hens in Côte d’Ivoire.
