| Abstract: | A review was made on the currently practiced feed-animal balance management system. The weakness and problems existed in the system were analyzed. According to the seasonal fluctuations of primary productivity of the grasslands, a new approach for the feed-animal balance management system was proposed. The proposed system is mainly based on restrain of grazing during critical period of grassland sensitive to grazing, together with the consideration of grassland forage production capacity and economical adjustment. Principle and operating procedures were described. |
