1 background introduction
Since 2003, China has begun to apply advanced RFID radio frequency identification technology to modern pig slaughter and processing enterprises, and has developed a real-time production monitoring and management system for RFID pig slaughter. The system can monitor the entire production process in real time, automatically, in real time, and accurately collect relevant data on the main production processes, health inspection, quarantine and other key links, and better meet the HACCP quality supervision requirements.
2 System application points
The application of RFID technology in the animal husbandry industry mainly has two aspects. On the one hand, it is to establish an animal husbandry management system for fine breeding of animals; on the other hand, it is to establish an animal tracking management system. Current beef product safety has become a key factor in the beef supply chain. In view of this, more than 20 countries and regions around the world have adopted RFID technology to track and trace their food production processes, and have achieved good results. The RFID-based beef tracking system identifies and connects management objects in the supply chain such as cattle growth, beef processing, storage, and retail, and then displays these identifications with bar codes and human readable methods. Once a beef product has health and safety issues, these signs can be used to trace, accurately narrow the scope of the safety issue, find out where the problem occurred, and trace the geographic location of the relevant place of production, slaughter or processing institutions, or even individual cattle. In this way, the supply of goods in these places can be blocked from flowing into the market, and then effective governance can be carried out.
3 Main application functions of the system
3.1 Install an electronic ID card for cattle
The first step in RFID-based cattle breeding and tracking is to install an electronic ID card on the cattle and establish a permanent digital file for each cattle to uniquely identify the attributes of each cattle. The basic methods of installing electronic tags for animals include: collar type, ear tag type, injectable type and pill type electronic tags.

3.2 Cattle Farm Management System Based on RFID
Write livestock information into the chip, including: livestock owner-owner’s name, gender, animal type, characteristics, immunization, vaccine type, manufacturer, production batch number, vaccination method, vaccination dose, immunization quantity, and immunization personnel’s name, etc. , The owner needs a handheld data collector and can obtain information about the livestock. According to the regulations of the Ministry of Agriculture of China, the cattle coding format is: 2-×××××× (county-level administrative area code)-×××××××× (identification sequence number). Other countries should be modified according to the local code.
The specific operation process is: in the daily management of animal husbandry, the owner only needs to carry a wireless handheld terminal to read the animal ear tag to be followed, and the relevant information of the animal can be displayed on the handheld terminal. Owners can feel this information to deal with their daily diet, medical history, reproductive history, immunization records, etc. accordingly. Fast and convenient, saving a lot of time. There is no need to look up the original acquisition file card. At the same time, the data can be transferred to the back computer, and the livestock file can be established in the back computer. Professionally record the detailed information of each livestock through the computer. No need to worry about illegible records or missing file cards. At the same time, the department and relevant leaders can check the situation of any ranches, stalls, and livestock instantly through the Internet to achieve information transparency.
3.3 Dairy cow precision feeding subsystem based on RFID
The digitization of fine aquaculture is based on a database system. In a distributed network environment, users of various business units can obtain and update data, store and manage data, extract and analyze information, and form basic data through the basic data warehouse mechanism of digital agriculture. Sharing and information mining. The knowledge and experience of precision breeding experts are abstracted, a data model is established to guide dairy cow breeding, and the feedback formed in the breeding practice is used to adjust the model.
The logical structure of the digital system for fine dairy farming is divided into a three-tier system structure: data layer, service layer, and application layer. The data layer is composed of digital agriculture basic data warehouse (including metadata database, image database, comprehensive feed nutrient database), sensor information database (including radio frequency sensor data, video surveillance data, etc.), expert model database and other database groups. The service layer is composed of a digital agricultural precision breeding support platform and an information sharing and exchange platform, including computer network systems, communication systems, monitoring systems, display systems, and operating systems. The application layer mainly includes a variety of application systems, as a client to call database server information and services.

3.4 Meat tracking system based on RFID
RFID technology can be applied to the entire process of animal husbandry food production, including feeding, epidemic prevention and sterilization, product processing, food circulation and other links. Standardized technical regulations and quality supervision measures are fully introduced to establish a “farm to table” food supply Chain tracking and traceability system.
1. The government takes the lead in building a meat food supervision platform to realize the information access and sharing of related companies and departments in all links of the supply chain, and realize end-to-end monitoring from the source of production to the retail link.
2. In the cattle breeding link, the whole process of feeding and tracking is realized through RFID technology and supporting auxiliary means, and the integration with the back-end livestock production management system is realized, and the docking with the livestock quarantine and inspection system of the competent department of the industry is realized. At the same time, the relevant information is input into the meat Food supervision platform.
3. In the beef transportation link, use RFID technology and supporting auxiliary means to deploy crossing monitoring systems on different transportation nodes to monitor the entire transportation process, and provide activities such as pig quarantine inspection and transportation disinfection. At the same time, relevant information is input into meat food Regulatory platform.
4. In the cattle slaughter process, RFID technology and supporting auxiliary methods are used to verify and confirm the health of the cattle, integrate the back-end management system of the slaughterhouse, and input relevant information into the meat food supervision platform.
5. In the beef processing link, RFID technology is used in conjunction with bar code technology to realize the correlation between cattle information and beef information. At the same time, relevant information is input into the meat food supervision platform.
6. In beef wholesale and retail links, RFID technology is used to accelerate the efficiency of logistics links, and bar code technology is used to trace its source information to strengthen its market transaction management. At the same time, relevant information is input into the meat food supervision platform.

4 Advantages of RFID technology in the application of animal husbandry industry
Electronic identification management has been used in Europe and America for several years and has become a showcase of technology. In addition to the application of automatic feeding and production statistics within the enterprise, it can also be used for animal identification, disease monitoring, quality control and tracking animal species. The main advantages of RFID technology in the livestock industry are as follows:
Contact automatic reading, real-time effective data collection method
, Is the use of non-contact radio frequency identification to collect and systematically manage the data in the electronic tags placed in the earlobe or body of the animal. It is an extremely effective management method for mastering the health of the animal and controlling the occurrence of animal epidemics.
Waterproof, can be applied to animal body
The low-frequency tag can penetrate water and animal bodies, and is not sensitive to water and metal. Whether the tag is placed on the animal body or on the cow’s ear, it can be read easily and quickly.
Unique number, 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. The electronic identification is one-time use, uniform number, and unique number. Through the traceable management of individual dairy cows, precise feeding is carried out to improve the feed-to-milk ratio; at the same time, health warning and milk quality monitoring are carried out to increase the production of high-quality milk, so as to greatly increase the economic benefits of the enterprise.
Combining with information technology is conducive to tracking management
Through the supporting software management program, the whole process of its growth cycle is monitored. For example, whether it is stocked in a pollution-free natural environment, whether the water, soil, and air indexes meet the standards, the use of veterinary drugs and additives, whether the feed has been contaminated by pesticides or residual additives, etc., and record where it was stocked in different periods. And important information such as its epidemic prevention status and health status. When the food animal meets the slaughter standard, the slaughterhouse will strictly consult the “quality file” of the animal. Only after strict inspection can the slaughter be carried out, and the “file” will be archived for future “quality traceability”.
