At present, China's animal husbandry is in a period of development and faces many problems. On the one hand, there is a large increase in livestock; On the one hand, there is a sharp decrease in forage. According to statistics, the number of livestock in Inner Mongolia pastoral areas has increased by five times in the past 50 years, while the available grassland has decreased by 90 million mu. The average available grassland per unit of livestock has decreased by nine times, and the overload is about half. Since 1997, the famous Xilingol Grassland in Inner Mongolia has overloaded more than 7 million livestock every year, resulting in the overgrazing and trampling of the forage grass without recovery.
