The treatments are: T₁= <em>ad libitum </em>(control), T₂= 8-12noon feeding (morning) and T₃= 12noon-4pm feeding (afternoon). Each treatment was replicated thrice with 10 birds per replicate. At 49^th day, three birds per treatment were randomly taken after starving them overnight for carcass evaluation. Analysed data showed that there was no significant effect of strain on live weight, carcass and non-carcass traits regardless of feed restriction employed. But Arbor Acre recorded higher net profit than Ross308 in terms of cost of production on strain basis. With regard to duration of feed withdrawal, dressed weight, eviscerated weight, carcass weight and back weight were significantly affected by the feeding regime imposed on the birds. Birds on <em>ad libitum</em> and afternoon feeding groups had higher and superior mean values to morning group. This implies that feeding birds in the afternoon under favourable conditions and improved management practices is beneficial and economically viable and profitable.</p> ER -
