Contribution to Knowledge of Food Formulation during Lean Periods in the Provinces of Wadi-Fira and West-Ennedi (Chad)

The effects of climate change have had a major impact on forage availability in the Sahel and Saharan regions Chad recent years. This has led to migration farmers search long-distance grazing, thus impacting potential animals produce good quality milk meat. It is with this mind that study was conducted knowledge feeding practices provinces Wadi-Fira West-Ennedi (Chad) during lean period. More specifically, it question collecting some information plants consumed by way which breeders formulate food ration their herds times deficit. emerges from investigation province faced deficit adapted consuming leaves, fruits seeds certain tropical such as Capparis decidua, Ziziphus mauritiana, Balanites aegyptiaca, Acacia tortilis, Boscia senegalensis, Salvadora percica Tribulis terristris compensate for shortages. same observation made West-Ennedi, since area desert annual precipitation 150 mm. Natural pasture only available around water points (ouadis oasis) small high number herds. Thus, also face drastic lack grazing periods. However, they adapt Bauhinia sp., senegalenis, terristris, angustifolia, Bicoma tomentosa, Blepharis linarifolia Aristida funiculata periods meet requirements. formulation feed differs one another. mainly based residues cereals millet (Panicum miliaceum) sorghum (Sorghum bicolor).
