| Summary: | Consumption and Food Digestibility by the Grass-Cutter Thryonomys swinderianus. Agricultural extension does not constitute an exact science but an art in which the proposed tricks tend to integrate all the rural development factors according to the different aims of decision makers. The utility of agricultural extension is often contested because of its high cost and its doubt ful efficacity. However, it remains the only transmission channel to bring the "knowledge" from the Research to the farmer. If agricultural extension in Africa dates from the colonial time, extension in matter of livestock, especially for small animals, is quite recent. It involves certain specificities that may include mainly human, economic and integration factors. This paper does not intend to formulate accurate rules but is to be considered as an exemple of a project which has developed some tracks in matter of strategy and methodology for small husbandry extension in rural area.
