Feeding trial lasting for eight weeks was carried out using a total of three hundred day old broiler chicks raised on deep litter to determine the growth performance and carcass characteristics of broiler chicks fed red sorghum diet supplemented with graded levels of methionine. They were fed five dietary treatments containing 0.1, 0.2, 0.3, 0.4 and 0.5% methionine representing T1, T2, T3, T4 and T5 respectively. The birds were divided into three replicates of twenty birds per replicate; making a total of sixty birds per treatment. The study was conducted in a Completely Randomized Design (CRD), and birds were randomly assigned to five dietary treatments. The experiment was divided into two phases, 1 – 4 weeks (starter phase) and 5 – 8 weeks (finisher phase). All data generated were subjected to one way analysis of variance (ANOVA). Differences between means were compared using Duncan Multiple Range Test. The daily feed intake (DFI) were not significantly (P>0.05) different, while the daily weight gain (DWG) were not significantly (P>0.05) different also. However, feed conversion ratio (FCR) was significantly (P<0.05) different in the starter phase but not in the finisher. Feed cost per kg weight gain also increased across treatments. Therefore, diet 1 which had 0.1% methionine gave the least cost per kg gain of N449.94 and it is the best point of production. From the result, it can be observed that red sorghum can be supplemented with graded levels of synthetic methionine at up to 0.5% level without adverse effect on the productive performance as it neutralizes the tannic acid effect of red sorghum.
