In recent years, the pollution of beef cattle breeding has aroused great concern from all sectors of society. The application of zero emission ecological breeding technology in beef cattle breeding can greatly reduce the emission of fecal sewage, reduce environmental pollution and impact, and improve the utilization rate of resources and improve the efficiency of beef cattle breeding. Taking the cattle raising technology in fermentation bed as an example, this paper analyzes the principle and advantages of zero emission ecological beef cattle raising technology in fermentation bed; The key points of zero emission ecological beef cattle breeding technology in fermentation bed were discussed.
