A study has been conducted on 400 chicks to evaluate conventional cottonseed kernels on broilers production. Groundnut cake has been substituted by cottonseed kernels at 0, 25, 50 and 75% levels. Cottonseed kernel incorporation decreased significantly (p< 0.001) the growing parameters, feed intake, feed efficiency and nutrients digestibility of the experimental diets. This reduction was proportional to the level of substitution. The study suggests that only the level of gossypol in cottonseed kernels limits their incorporation in broilers diets and that this by-product should be excluded from the formulation in broilers production or that its level of incorporation should be limited to a maximal level of 10% when production duration is not a constraint for breeders.
