| Abstract | West Africa, with 37.2% of the total goat herd on this continent, is one of the main breeding basins of this species whose socio-economic role is particularly important. Goats are reared in various agroecological and production systems, but they are mainly present in the most arid areas where they play a key role in subsistence and in agrarian systems. The production systems are primarily traditional (pastoral, agropastoral and sedentary) and secondarily periurban. The productivity of goat farms is low. Age at first kidding is on average 15.3 months for a kidding interval of 295.8 days and a prolificacy of 1.46. The latter is however higher in the dwarf goat where it can reach 1.85. Preweaning mortality is very high and represents the main constraint for goat production in West Africa. It is caused by lung diseases, mainly peste des petits ruminants , and by gastrointestinal parasites. The growth rate is also low with an average body weight at 12 months of age not exceeding 20 kg, except in rare genetic types. To improve goat breeding productivity, it is suggested: i) to reduce the preweaning mortality rate by focusing in particular on the control of gastrointestinal parasites, ii) to set up a strategic supplementation based on the optimum ruminal use of fibrous feed, and iii) to develop genetic improvement programs involving community management in an enhanced social and professional context. |
