Abstract: With the initial formation of a new pattern of modern large-scale farming, and the continuous emergence of intelligent dairy farming devices, the development of dairy cow feeding technology has shown a trend of informatization, refinement and intelligence. This article analyzes the characteristics and application of the dairy cow’s total mixed ration feeding technology and the dairy cow automatic feeding equipment system, and summarizes the domestic and foreign dairy cattle breeding technology and equipment. The domestic small and medium-sized farms still have low level of automation and feeding technology. Problems such as imperfect integration with equipment and low feeding efficiency; large-scale breeding farms face the problems of importing core technologies, high breeding costs and high equipment development costs; foreign intelligent breeding equipment technology is relatively mature, and related equipment systems have been widely used use. In addition, based on the current research status at home and abroad, the improvement direction of China’s feeding technology and equipment is proposed, the equipment and technology are researched and developed according to the actual breeding situation, the promotion and application of China’s independent equipment and core technology are promoted, and the development of dairy cattle breeding equipment and technology is refined and intelligent., Effectively improve the level of dairy cattle breeding in China.
