Research progress of grassland feed-animal balance at home and abroad.

Feed-animal balance is the key technique on the grassland ecosystem management, and attracts widespread attention in the world. Many studies have been conducted by former researchers, and most of their efforts were intended to keep the balance of feed-animal. However, there are still much more issue needed to be studied in details on the face of grassland degeneration and animal husbandry sustainable development. The author analyzed the feed-animal balance research progress, including the concept of stocking rate and its practical management techniques, especially on the stocking rate calculation methods. In addition, the social and economy effects on feed-animal balance were also discussed during the progress of improving the development of pastoral economy. In order to achieve feed-animal balance more effectively, it was concluded that the focus must be shift from only on animal number to the grassland quality, and it’s necessary to strengthen market tax control.
