*2.1.1 Evaluation of selected agro-industrial waste wheat offal, maize offal, and rice bran in poultry diet*

The use of agro by-products in feeding chickens varies in the growth performance of the birds mainly as a result of the feed quality, varieties, period of storage, and the atmospheric condition. Many authors had earlier reported the safety of agro by-products in the diet of broilers in the tropics [21, 22]. Makinde and Inuwa [23] reported the growth performance of grower's turkey fed agro by-products each at 15% involving wheat offal, rice bran, and maize offal. The growth indices (feed intake, weight gain, and feed conversion ratio) and carcass characteristics were similar with their counterpart fed the control diet. In conclusion, they affirmed that the dietary inclusion of 15% wheat offal has no detrimental effect on the growth, carcass, and health of the birds.
