An experiment was conducted for 90 days to assess the effects of diets formulated based on locally available feed ingredients on growth performance, feed conversion ratio (FCR) and gross margin of cattle under feedlot condition in Kogwa district, Tanzania. Fifty bulls belonging to Tanzania shorthorn zebu breed, with the age of three to four years and average initial weight of 130 kg were used. The bulls were allotted to five treatments (T 1 , T 2 , T 3 , T 4 , T 5 ) in a completely randomized design. Animals on treatments T 1 , T 2 , T 3 and T 4 were kept under confinement, fed Cenchrus ciliaris hay and supplemented with concentrate diets formulated based on locally available ingredients while those on T 5 were grazed in natural pastures without being supplemented. The diet on T 1 contained maize bran as the sole energy source while T 2 comprised maize bran and rice polishing as energy sources, T 3 comprised maize bran and molasses as energy sources and T 4 had maize bran, rice polishing and molasses as energy sources. All diets contained sunflower seed cake and mineral pre-mixes as protein and mineral sources, respectively. The bulls subjected to concentrate supplementation (T 1 , T 2 , T 3 , T 4 ) had higher (P < 0.0001) weight gain and growth rate than those on T 5 . Among the bulls supplemented with concentrate diets, those on T 3 had the highest weight gain (107 kg) and growth rate (1.28 kg/d) and lower FCR (6.48), followed by those on T 1 (weight gain = 96.70 kg, growth rate = 1.07 kg/d, FCR = 6.509). Moreover, the bulls on T 3 had the highest gross margin (TZS 235,471). In conclusion, the diet on T 3 was found to be better than the other diets. Therefore, it can be used by farmers for fattening of indigenous cattle at an affordable cost and obtain large profit.
