Brewer's waste is one of the promising carbohydrate and protein source by-products for fish diets. A 10-wk feeding trial experiment involving 10 different diets (10 diets for Spent millet, from locally fermented drink (Burukutu) with increasing levels of brewer's waste (40% crude protein) was carried out to evaluate the use of spent millet, from Burukutu production in Clarias gariepinus diets in place of normal Corn. Growth performance was compared against a control diet formulated to have

The diets were isonitrogenous and isocaloric. A relatively good growth performance and nutrient utilization by Clarias gariepinus fed the test diets were observed. However, the results showed significant difference (p<0.05) in weight gain, SGR, FCR and RGR between treatments, with the control performing best. The result also showed that survival rate was high in all the treatment which indicate that, spent millet from burukutu production has no adverse effect on the experimented fish. Based on this research, it wasconcluded that 50% of the corn carbohydrate in a typicalcommercial diet could be replaced with spent grain (millet) from locally fermented drink (BKT) withno adverse effect on growth and feed utilization for Clarias gariepinus.
