This study investigated the effect of feeding graded levels of fermented mixtures of cassava and palm kernel cake on the performance of broilers. Cassava root pulp and palm kernel cake were mixed in the ration of 3:1 and allowed to ferment in an air tight environment for six days and after that was sundried. The product was referred to as FCP mix. Fifty six days feeding trial was conducted using one hundred and sixty arbor acre chi cks that were initially raised on a commercial starter diet for a week. After one week, the birds w ere weighed and randomly separated into five groups of thirty (30) birds each. Each group was further subdivided into three replicates of ten (10) birds each . Five diets were formulated with diet 1 as the control diet while 2, 3, 4 and 5 had a replacement level of 25%, 50%, 75% and 100% of maize. At the end of the trial, 2 birds per replicate, giving a total of 30 were slaughtered to compare the internal organ s such as gizzard, heart, abdominal fat. There were significant differences (P<0.05) in live weight and average daily weight ga in but no significant differences (P>0.05) were observed for feed intake an d feed conversion ration. The fin al live weight of bir ds fed diet containing 100% maize replacement level was similar (P>0.05) to that of the control. Feed cost per bird decreased progressively with increase in the inclusion level of F CP mix. No significant differences were found for the proportion of breast muscle, drumstick, wing and neck across treatment groups. Full gizzard weight in birds fed 50% FCP mix (3.59%) was significantly higher when compared to other treatments. There were significant differences (P<0.05) in cooking loss, water holding capacity a nd drip loss. Tenderness score for meat from bird in control diet was the lowest. There were no significant different (P>0.05) found among haemoglobin content, pack cell volume and red blood cells. It was con cluded that FCP mix could completely replace mai ze without adversely affecting the overall growth performance of the bird.
