The lowest feed cost per kilogram weight gain (N208.21) was recorded at 75% CRLMM level of replacement. This indicated that inclusion of 75% CRLMM is more cost effective than other treatments. This therefore indicated that the use of CRLMM is cost effective when used as a replacement for maize at 75% level of inclusion of CRLMM. Ukachukwu (2008) reported similar findings when broilers were fed cassava-based diets.
