Cette synthèse aborde les multiples rôles (sociaux, culturels, économiques, religieux, alimentaires et agricoles) de l’aviculture villageoise dans la lutte contre la pauvreté et l’insécurité alimentaire des populations africaines. Elle décrit les caractéristiques des différents systèmes existants (extensif et amélioré) et les pratiques d’alimentation observées dans ce sous-secteur avicole. Après avoir passé en revue les variétés phénotypiques existantes dans la population de poules locales africaines et les performances zootechniques des sujets exploités au Sénégal et dans diverses régions d’Afrique subsaharienne, elle met un accent particulier sur les différentes contraintes (précarité des d’habitats, fortes mortalités, maladies aviaires, prédateurs, irrégularité et déficit d’approvisionnement alimentaire, accès au crédit…) qui freinent le développement de l’aviculture traditionnelle au Sénégal et en Afrique subsaharienne.

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.

In the prospect of the Cassia tora leaves meal recovering as a protein ingredient source for diets of Senegal indigenous chickens, a study was carried out to determine their nutrient utilisation and nutritional value. Twenty adult Senegal indigenous chickens were housed in metabolic cages and allotted in four groups of five birds each. The groups were corresponding to four dietary treatments (CT0, CT5, CT10 and CT15) containing respectively 0, 5, <br />10 and 15% of cassia leaves meal in substitution of groundnut cake meal. The cassia leaves are relatively rich in protein (27.4% DM), crude fibre (16.8% DM), NDF (25.7% DM) and ash (15.2% DM), particularly in calcium (3.1%) and potassium (1.3% DM). It contained 3.8% DM, 36.8% DM and 2050.47kcal/kg DM of ether extract, nitrogen-free extract and metabolizable <br />energy, respectively. Except for fat, the inclusion of Cassia tora leaves meal in the indigenous poultry diets until 15% has no significant adverse effect on nutrient and energy utilization, feed intake, average daily weight gain and feed conversion of the Senegal indigenous poultry. It significantly improved the crude fibre and ash utilization from 5% dietary treatment (CT5). [less ▲]

In the prospect of the Leuceana leucocephala leaves meal using as a protein ingredient source for indigenous Senegal chickens diets, a study was carried out to determine their nutrient utilization and nutritional value when incorporated at various levels in the diets. Twenty adult indigenous chickens with an average body weight of 1.22 kg were conducted in metabolic cages and allocated in four groups of five birds each. The groups were corresponded to four dietary treatments (LL0, LL7, LL14 and LL21) containing respectively 0, 7, 14 and 21% of Leuceana leaves meal. During the trial, birds were weighed at the beginning and at the end. Feed offered and refused, collected fresh excreta were weighed daily and the droppings were oven-dried at 60oC and ground per bird for six days. The ingredients and experimental diets used and collected excreta were subjected to chemical analyses. Results showed that the Leuceana leaves were relatively rich in protein (24.9% DM), ether extract (6.4% DM), crude fiber (14.2% DM) and Neutral detergent fiber (22.4% DM). It contained respectively 43.1% and 11.4% DM of nitrogen free extract and ash, particularly calcium (1.8%) and potassium (1.1% DM) and 2573.8 kcal/kg DM of metabolizable energy. The results of the trial showed that the inclusion of L. leucocephala leaves meal in the diet at 21% level, has no significant adverse effect on feed intake, average daily weight gain, feed conversion ratio and nutrients utilization (except ether extract) of adult indigenous Senegal chickens. It has significantly (p<0.05) improved the crude protein and metabolizable energy utilization in birds fed the 7% level inclusion diet (LL7). [less ▲]
