Milk is a kind of high nutritional energy supplement food, which is suitable for all ages and plays an important strategic role in improving the physical quality of Chinese people. However, China's dairy industry is relatively backward; both per capita intake and per unit yield of dairy cattle are at the international low level, the main reason is still the backward dairy management system. At present, the research in this field at home and abroad is mainly based on sensor technology and neural network, but there are various deficiencies. In order to solve this problem, this paper proposes a cow feeding management system based on electrical automation. RFID technology is one of the core technologies of the management system in this paper. It can collect the information of dairy cows in real time by setting electronic tags. The electric automation cow feeding management system is based on the n-layer C / s system structure under the framework of. Net. SQL Server 2005 is used as the background database. The system in this paper basically realizes real-time monitoring, intelligent reminder, and sets up a functional module management system. The system covers the whole process from rising to selling, and has strong source tracing function. Finally, in the specific test comparison, through the test data, we can see that the electric automatic cow feeding management system in this paper has greater advantages than the traditional method. In particular, the milk production of dairy cows has been greatly improved, and it is obviously helpful for the recovery of the body of dairy cows. The experiment shows that the management system of this paper can be used to manage dairy cows scientifically and effectively.nannies". On the whole, China's dairy industry is still in the state of "small, loose and low "Small" refers to the small scale of dairy farming. In 2001, the scale of dairy farming in China was 6.753 million, with an average scale of about 4.5. "Free range" means that cows are raised in tens of thousands of families in China, of which more than 93% are raised by individuals. They are very scattered, and the cost of production, collection, storage and transportation of milk is relatively high. "Low" refers to the low level of production and low degree of industrialization. The average output of China's adult cows is more than 3100 kg, while that of the United States, Israel and other countries is more than 8600 kg, and that of Sweden, Denmark, France, Japan and other countries is more than 6600 kg. In 2005, China's per capita milk consumption was only 17.3kg, less than 1 / 6 of the world average, less than 1 / 3 of the Asian average. In addition, the production technology of dairy industry is backward, and the national mechanical milking rate is less than 25%.
