Description: Das Projekt "The forage potential of tanniniferous legumes: Search for sustainable ways to cope with nutritional limitations in tropical smallholder livestock" wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich, Institut für Nutztierwissenschaften, Professur Tierernährung.Ruminants play an important role as assets and sources of high quality food and income for rural populations in the developing world. Ruminant productivity is usually low due to inadequate nutrition (i.e. protein deficiency). Promising forage species, mainly legumes, have been identified to overcome these limitations. Many of these legume species contain tannins that could be either advantageous or disadvantageous in terms of feed efficiency and metabolizable protein supply to the animal. The overall aim of this project is to develop efficient feeding systems based on tanniniferous shrub and tree legumes in order to improve livestock productivity and to alleviate poverty of smallholders in the tropics. This will by achieved through (i) studying the effect of plant nutritional status on the accumulation of condensed tannins in legumes, and the influence of these tannins in ruminant nutrition and the nitrogen fertilizer value of animal excreta for plants, and (ii) designing optimal feeding strategies based on the use of tropical forage legumes with different tannin content to overcome the limitations of ruminant diets in protein supply. Finally, the results will be assessed by an ex-ante economic analysis at farm level and at ecoregional levels. The outcomes of this work will provide the necessary background information for better feeding practices based on tanniniferous legumes. The project is part of the Research Priority Area on 'Livestock Systems Research in Support of Poor People of the Swiss Centre for International Agriculture.
