Abstract: Accurately predicting grass yield and livestock carrying capacity of grassland is essential for the sustainable development of herbivorous animal husbandry. It can effectively regulate the grazing quantity and quality,protect grassland,and help improve livestock performance. The domestic and foreign prediction models and accuracy for estimating grassland yield and stocking rate were summarized in this review. In addition,the advantages and disadvantages of various models were analyzed,and major problems existed in grassland management and the direction of future efforts were presented as well. We aimed to provide references for grassland conservation and utilization,and provide better ideas for the sustainable management of grassland resources in China.

Key words: Grassland production, Stocking rate, Livestock carrying capacity, Prediction models
