This study was conducted in two separate trials to compare the effects of graded levels of toasted Bambara Nut Waste (TBNW) and Soya Bean Hulls (SBH) on growth performance, haematology, carcass and linear measurement of broiler chickens. One hundred and twelve 28-day old broiler birds of Anak strain were divided into 7 groups of 16 birds each. The birds were assigned to 7 treatments of diets which include: a control, three Soya Bean Hulls (SBH) levels (10%, 20% and 30%), and three Toasted Bambara Nut Waste (TBNW) levels (10%, 20% and 30%) for 28 days (age 28-56 days). Each treatment was replicated twice with 8 birds per replicate. The result shows that final body weight, feed conversion ratio and protein efficiency ratio of finisher birds fed the diets containing 10% bambara nut waste was the best (p<0.01), and those on diet containing 10% soya bean hulls was significantly better than diets containing higher percentages of the test ingredients, as well as the control diet which is comparable with that of the diets containing 20% each of the test materials.There were no significant differences in average daily feed intakes of the birds fed graded levels of Bambara nut waste and those fed Soya bean hulls and there were no significant differences in average daily weight gain among treatments. The result of the haematological indices showed that broiler birds fed diets containing 10% of both Bambara Nut Waste and Soya Bean Hulls had the best White Blood Cell count. The birds fed diets containing 20% and 30% levels of Bambara Nut Waste had better White Blood Cell count than birds fed 20% and 30% levels of Soya Bean Hulls. The birds fed diets containing 10%, 20% and 30% levels of Bambara Nut Waste had better Packed Cell Volume percentage than those fed diets Soya Bean Hulls. The Packed Cell Volume values of birds fed Bambara Nut Waste were significantly different but statistically the same.The live weight, de-feathered weight, dressed carcass weight, weight of feathers, neck length, thigh length, thigh diameter, length of bird and weight of feathers varied significantly (p<0.01) while the shank length variations are insignificant. The live weight of the birds fed 10% level of bambara nut waste were significantly higher than the birds fed the control diet treatment and all other treatments. The live weights of birds fed 20% level of bambara nut waste were significantly higher than that of birds fed 20% levels of Soya bean hulls. The result of this study indicates that while soya bean hulls inclusion level of 20% and above may not be very promising in broiler diets, toasted bambara nut waste inclusion level of 10% is the best and is recommended along with soya bean hulls inclusion level of 10% for broiler diets. Up to 20% inclusion level of bambara nut waste in diets is promising, and is also recommended, especially for broiler finisher diets.
