Electronic identification management has been used in Europe and the United States for several years and has become a showcase of technology. In addition to the application of automatic rationing and production statistics in the enterprise, it can also be used for animal identification, disease monitoring, quality control and tracking of animal species. The advantages of RFID technology in the livestock industry are as follows:

(1) Contact automatic reading, data collection method is real-time and effective
It uses non-contact radio frequency identification methods, such as RFID animal ear tags, to collect and systematically manage the data in the electronic tags placed in the animal earlobes or in the body. It is an extremely effective way to grasp the health status of animals and control animal epidemics management method.

(2) Waterproof, can be applied to animal body
The use of low-frequency tags can penetrate water and animal bodies, and is insensitive to water and metals. Whether the tag is placed in the animal body or on the cow's ear, it can be easily and quickly read.

(3) The number is unique, not easy to forge, easy to manage
When the animal is born, the electronic identification is placed in the earlobe or body of the animal, and the electronic identification is one-time use, uniformly numbered, and unique. Through the traceable management of individual dairy cows, precision feeding is carried out to improve the ratio of feed to milk; at the same time, health warning and milk quality monitoring are carried out to increase the output of high-quality milk, so as to greatly increase the economic benefits of the enterprise.

(4) Combining with information technology is conducive to tracking management
Through the supporting software management program, the whole process of its growth cycle is monitored. Such as whether it is stocked in a non-polluting natural environment, whether the water, soil, air and other indicators meet the standards, the use of veterinary drugs and additives, whether the feed has been polluted by pesticides or residual additives, etc., and record the pasture where it was stocked in different periods. As well as their epidemic prevention, health status and other important information. When a food animal reaches the slaughter standard, the slaughterhouse will strictly check the "quality file" of the animal, and only after passing the strict inspection can it be slaughtered, and the "file" will be archived for future "quality traceability".
