A total of 200 male and female day-old chicks of local stock, with an average weight of 25�2 g, were divided randomly into 4 groups of 50 individuals, each group distinguished by the respective rate of substitution of corn by cull dates (0 %, 20 %, 30 % and 40 %) for a period of 48 days. Each group was divided into ten (10) packages of 05 subjects. The live weights after 48 days improved for all experimental groups, recording an increase of + 162 g (20 %) ; + 82 g (30 %) and + 31 g (40 %). All of the characteristics remained unchanged for all groups with the exception of liver weight, which was lower in the experimental groups. Substituting 40% of the corn by culls dates while adding 250 ml rumen content extract per kilogramme of broiler chicken feed increased the live weight and average daily gain.
