The weight variations of grazing goats and sheep in the desert steppe in winter and spring
Grazing ecosystem was the necessary process in which grassland ecosystem converted from primary production to secondary production.Livestock productivity was not only the important items of plant‐animal‐interface in the grazing ecosystem,but also one of the important indices of evaluating grazing system and grassland conditions.Livestock weight variations which including live weight and daily weight gain were the direct reactions of grazing movement to livestock‐plant‐soil system,influencing directly farmers′economic returns.
