to study the effect of incorporation of cassava foliage meal (cfm) at increasing levels (0; 2.5; 5 and 7.5%) in food rations for broilers on carcass traits and retail cuts yield were used 32 broilers, females, cobb breed, with 42-d old). the analysis of variance detected significant effects (p <0.05) of level of inclusion of cfm on the head percentage. the highest values in head percentage (3.26 and 2.72%, respectively) were found with 5 and 7.5% of cfm. the inclusion of cfm only showed an increase of 6% (p <0.05) for the percentage of leg (drumstick-thigh combination) and leg quarter (with the back portion included). however, the chilled carcass yield was not affected significantly by the treatments. the use of cfm in feeding stuffs for broilers up to 7.5%, did not cause a detriment of the productive performance and did not has a negative effect on slaughter characteristics or retail cuts yields.
