This study was carried out to assess the nutrient composition of some unconventional and local feed resources available in Senegal so as to use them as protein supplement sources in the diets of indigenous chickens to enhance their productivity. Ten (10) unconventional and local ingredients from Senegal including leguminous leaves (Leuceana leucocephala, Cassia tora, Moringa oleifera, adansonia digitata, Sesbania rostrata), cucurbit (Citrullus vulgaris) and roselle (Hibiscus sabdariffa) seeds, red and white cowpea (Vigna unguiculata seeds) and cockroaches (Blatta orientalis) were collected, sun-dried, processed into meal and analyzed for their chemical and macro-mineral composition using internationally established procedures. The results showed that the samples Dry Matter (DM) percent ranged from 89.3% (red cowpea) to 94.9% (C. vulgaris). The Crude Protein (CP) content ranged from 24.7% (white cowpea) to 61.9% (cockroaches meal), with A. digitata leaves having the lowest value (12.9%). Citrullus and Hibiscus seeds meal recorded the highest (38.8% and 18.9%) Ether Extract (EE) values, followed respectively by cockroaches (11.1%), Moringa (9.8%), Leuceana (6.4%) and Sesbania leaves meal (5.1%), while the others were below 4.5%. The crude fiber (CF) content was globally high in the leaves, ranging from 11.7% (M. oleifera) to 16.8% (C. tora) while that of seeds and cockroaches ranged from 1.9% (white cowpea) to 19% (Citrullus seeds). A. digitata leaves gave the highest ash content (25.2%), followed by Cassia (15.2%), Moringa (13.6%), Leuceana (11.4%) and Sesbania leaves (7.1%), while the others were below 5.6%. The metabolizable energy (ME) value calculated for seeds and cockroaches meal ranged from 3161 kcal/kg DM (cockroaches) to 4270 kcal/kg DM (C. vulgaris) and that of leaves from 1873 (A. digitata) to 2888.9 kcal/kg DM (M. oleifera). Cassia leaves contained the highest level of calcium (3.1%), followed by Adansonia and Leuceana (1.81%), Moringa and Sesbania leaves (1.41%), whilst cockroaches, Hibiscus and Citrullus seeds meal recorded respectively 0.93, 0.81 and 0.55% of phosphorus. These results showed that all the ingredients samples contained appreciable quantities of all dietary nutrients tested for which more or less make them partial or complete substitutes for the conventional feed sources.

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. [less ▲]
