Description
In a grazing trial with Tibetan sheep at Haibei Research Station of Ecosystem, the relationships between stocking rate, live-weight gain per animal and live-weight gain per ha were studied in a Kobresia humilis meadow pasture. Stocking rates were 2.14 (A), 3.12 (B), and 6.07 (C) animal/ha. Grazing was rotated in a summer-autumn pasture (from July to October) and in a winter-spring pasture (from November to June of next year). Under different stocking rates, changes in horizontal and vertical plant community composition have taken place. The decreases of live-weight gain per animal and of herbage yield with increased stocking rate were linear. Live-weight loss increased with increased stocking rate in the winter-spring pasture. Live-weight gains per ha were 29.07 Kg for (A), 38.28 Kg for (B) and 22.56 Kg for (C). The experiments showed that grazing by 3.29 animal/ha was optimal and that grazing by 6.07 animal/ha caused deterioration of the Kobresia humilis meadow pasture.
