| Stocking rate and grazing systems are dominant factors affecting stability of grasslands and animal productivity especially of high sensitive ecosystems like steppe of Inner Mongolia. High grazing intensities may maximize feed intake and animal performance per area of land within a short time period, however decrease on long term grassland productivity. The development of adapted grazing systems can increase animal performance and the income of farmers without negative effects on ecology. To determine optimal stocking rate grazing experiments are performed, where the effects of different grazing systems and stocking rates on live weight gain, feed intake and feed quality are measured. The quality of pasture is estimated by the nitrogen content of faeces of the animals as an internal marker. The feed intake of the grazing sheep will be assessed by the digestibility of the grass and the amount of faeces per animal estimated by titanium dioxide as an external marker. To evaluate the sustainability of the respective grazing systems and intensities, the studies are based on long term experiments including traditional and improved land use systems. |
