Abstract: In order to address animal epidemics and mitigate the adverse effects of nonranch personnel on dairy farming production, a solution was proposed to build a digital twin dairy farm monitoring platform by incorporating digital twin technology according to the needs of the dairy farm. The platform was built based on the digital dairy twin farm model (DDTM), which consisted of three parts, namely, the geometric model (GM), the information model (IM), and the prediction model (PM) of the digital dairy farm. The 3ds MAX software was used for GM to geometrically model the buildings, cows, and equipments in the dairy farm, and ultimately to achieve the threedimensional visual effect of the dairy farm. For IM, the mapping between digital twin dairy farms and actual physical dairy farms was realized by means of specific twin identification system, remote data uploading and analysis. And for PM, a prediction model was used to predict the trend of temperature and humidity changes in the barn to guide the health and production of dairy cows. This comprehensive programme provided innovative ideas and practical references for the construction of future digital twin dairy farms, which will promote the sustainable development of digital livestock  and improve the efficiency of dairy farming.
