Effets de l’incorporation de la farine de feuilles de Cassia tora (Linn.) dans la ration alimentaire sur les performances de croissance, les caractéristiques de la carcasse et des organes et le résultat économique chez des jeunes poulets traditionnels du Sénégal.

The aim of this study carried out from October 2010 to January 2011 was to evaluate the effects of Cassia tora leaves meal inclusion in the diet on growth performances, carcass and organs characteristics and economics results of indigenous Senegal chickens. Eighty eight (88) indigenous Senegal chicks of 6 weeks old were randomly divided into four groups of 22 chicks each with similar body weight. Each group allotted in two repetitions of 11 birds, corresponded to four (4) dietary treatments CT₀, CT₅, CT₁₀ and CT₁₅containing respectively 0, 5, 10 and 15% of cassia leaves meal in substitution of groundnut cake meal. During the trial (7-18^th week old), zootechnical parameters of birds and economical data were recorded, processed and analyzed per dietary treatment. From 7 to 18 weeks old, the final live body weights (LBW) were 694.36 g, 880.41 g, 763.14 g and 708.64 g/bird, the average daily weight gain (ADWG) were 5.6 g, 7.81 g, 6.4 g and 5.73 g/day, the daily feed intake (DFI) of 25.66 g, 31.02 g, 34.64 g and 32.51 g/bird and the feed conversion ratio (FCR) of 5.83, 4.79, 7.44 and 8.87 respectively for birds fed CT₀, CT₅, CT₁₀ and CT₁₅ diets. The C. tora leaves meal inclusion up to 15% in the diet did not cause any adverse impact on LBW, ADWG, DFI, mortality, carcass and organs characteristics of these birds compared to their controls. Except for the significant FCR deterioration in birds of CT₁₀ and CT₁₅, significantly better growth performances, feed costs and economic margins were recorded with birds fed the CT₅ diet, making thus of this last treatment the single most economically profitable (+205 FCFA/kg carcass of additional) compared to control.
