||The purpose of this study carried out from July to October 2010 was to assess the effects of Moringa oleifera leaves meal inclusion in diets on growth performances, carcass and organs characteristics and economics results of growing indigenous Senegal chickens. Ninety six (96) indigenous Senegal chicks of 5 weeks old were randomly allocated into four groups of 24 chicks each with similar body weight. Each group subdivided in two repetitions of 12 birds, corresponded to each of the four (4) dietary treatments MO0, MO8, MO16 and MO24 containing respectively 0, 8, 16 and 24% of Moringa leaves meal in substitution of groundnut cake meal. During the experiment (6-17th week old), zootechnical parameters of birds and economical data were recorded and analyzed per dietary treatment. At the end of the 12 weeks trial, the final Live Body Weights (LBW) were 721.60 g, 911.70 g, 812.85 g and 720.05 g/bird, the average daily weight gain (ADWG) were 6.49 g, 8.77 g, 7.61 g and 6.50 g/day, the Daily Feed Intake (DFI) of 39.10 g, 39.76 g, 36.28 g and 34.24 g/bird and the Feed Conversion Ratio (FCR) of 7.58, 5.75, 6.11 et 7.24 respectively for birds fed MO0, MO8, MO16 and MO24 diets. The Moringa leaves meal inclusion in the diets up to 24% had not caused any adverse impact on LBW, ADWG, FCR, mortality, carcass and organs characteristics in birds compared to their controls. Except the significantly decrease of DFI obtained in birds of MO16 and MO24 treatments, significantly better growth performances, feed costs and economic margins were recorded in birds fed MO8 and MO16 diets. Thus these two dietary treatments were the only most economically profitable (respectively 357 and 206 FCFA/kg carcass of additional profit) compared to the control.
