A 12 week feeding trial was conducted using three hundred and sixty point of lay Haco strain of pullets to evaluate the effect of feeding diets containing sun-dried cassava peel meal (SDCPM) and lye-treated cassava peel meal (LTCPM) on their performance. Nine experimental diets were formulated. The SDCPM and LTCPM were included at the rate of 50, 60, 70 and 80% levels, respectively, to replace maize of the control diet. The birds were randomly allotted to nine dietary treatment groups. Diet 1 was the control containing 0% of either SDCPM or LTCPM. Diet 2, 3, 4, and 5 had 50, 60, 70 and 80% of SDCPM, respectively, while diets 6, 7, 8 and 9 had 50, 60, 70 and 80% of LTCPM, respectively. There were four replicates per treatment with ten birds per replicate in a completely randomized block design experiment. The treatment method influenced the cyanide level of the cassava peels. The lye-treated cassava peels had lower cyanide level than the sun-dried peels. Hen day production of the birds fed 50% SDCPM (70.00%), 50% LTCPM (70.40%), 60% LTCPM (70.80%) and 70% LTCPM (69.90%) was significantly better than in control birds (71.00%). A similar trend was observed for feed conversion efficiency. Birds fed with diets containing cassava peels (SDCPM or LTCPM) had significantly lower yolk weight and blood cholesterol values than those fed with maize based diets. The main blood characteristics of birds fed 70%, 80% SDCPM and 80% LTCPM were lower than those in control birds. It can be concluded that up to 50% of SDCPM and 70% of LTCPM can be used in layer diet to replace maize without adverse effects on performance and blood characteristics of laying chickens.
