\textbf{Abstract}
\begin{abstract}
\normalsize{
A 56-day study was conducted to assess potentials of housefly maggot meal (magmeal) as substitute for soymeal in diet of broiler chicks. Growth performance, carcass trait and organoleptic test were measured. Economic cost of broiler from starter phase (day"=old) to finisher phase was evaluated. Sixty"=four broiler chicks (mixed sexes) were randomly assigned to four treatment groups with sixteen broiler birds per treatment. Each treatment was replicated four times in completely randomised design. Broiler chicks were fed commercial broiler starter ration containing \mbox{24\,\%} crude protein and \unitfrac[2800]{kcal}{kgME} for the first 7-days to stabilise them. Four experimental diets containing 23.46$\pm$\mbox{0.41\,\%} CP (Mean$\pm$SD) were formulated. Soybean meal content in the diets was substituted by \mbox{0\,\%}, \mbox{20\,\%}, \mbox{40\,\%} and \mbox{60\,\%} levels of magmeal inclusion respectively. Control diet contained \mbox{0\,\%} magmeal. At the end of experiment four birds per treatment (one per replicate) were randomly selected, weighed and slaughtered for carcass and organ evaluation. Another set of four were used for organoleptic test. Samples from all 4 treatments were subjected to identical curing process. Nine desirable qualities were considered and included colour, taste, texture, flavor, juiciness, oiliness, softness, breakability, and general. Samples were `blinded' and randomised before assessment. Trained sensory evaluation panelists assessed the samples based on the Hedonic scale. Results showed that, final live weight, total weight gain, total feed intake and feed conversion ratio were not significantly ($p > 0.05$) influenced by the diets. Broilers on treatment 3 (\mbox{40\,\%} magmeal inclusion) showed a marginal but no significant increase in final live weight value of 2825g, The cost of production indicated that there were no significant differences ($p > 0.05$) among treatments. Data from organoleptic test revealed that cured meat samples from all four treatments demonstrated comparable results. Treatment 4 with \mbox{60\,\%} inclusion of magmeal recorded higher mean values in terms of oiliness, softness and breakability relative to T3, and T2 and Control, though not statistically different ($p > 0.05$). Even though magmeal could be included in diet of broiler chicks up to \mbox{60\,\%} level, broiler birds appeared to perform better at the inclusion level of \mbox{40\,\%} magmeal.  Magmeal is not used as human food as the case with soybean. }
