Series of studies on balance control between animal demanding and feed availability (3)Improvement of the current estimation methods for animalfeed balance

On the basis of shortcomings in current estimation method for animalfeed balance estimation, this study firstly proposed a management pattern and technical approach, in which the grassland resource was basic, and the time was critically controlled, and economic threshold was used to balance; secondly, this study briefly introduced the selection of some parameters and calculation procedure; finally, this study discussed the advantages of the newly proposed method by taking the grassland of Inner Mongolia Autonomous Region as sample.
