Résumé
The present study was conducted within the framework of the Sino-German MAGIM-project (“Matter fluxes of Grasslands in Inner Mongolia as influenced by stocking rate”, 2004 – 2010) and the LOTGras-project (“Long-term strategies towards improved grassland productivity in semi-arid environments”, 2010 – 2013) funded by the Deutsche Forschungsgemeinschaft DFG (German Research Foundation). In the MAGIM-project, biological aspects (e.g. grazing intensity, grazing management system, vegetation productivity and species composition, and soil parameters) of the Inner Mongolian steppe ecosystem were studied with the aim of reducing the ecological problems mainly associated with overgrazing in this region. LOTGras focused on precise feed supplementation to improve sustainable animal productivity and avoid degradation of the plant community. The objectives of this study were to evaluate the effects of different feeding strategies, in particular looking at the impact of grazing intensity, grazing management system and concentrate supplementation on feed intake, digestibility of organic matter intake and live weight gain of grazing sheep and on grassland condition in a semi-arid and arid pastoral system.
