Application standard and application analysis of RFID in animal husbandry management

　　Among the series of application standards for RFID, the ISO 11784/ISO 11785 standard is used for animal identification. The international label does not specify the size of the sample, so it can be designed into various styles suitable for animals, such as glass tubes, ear tags or collars, etc.

　　The ISO 11784 standard specifies the code structure for animal identification, which is composed of 8 bytes and 64, of which the 27-64 bit encoding method is specified by the user country.

　　The ISO 11785 standard specifies technical guidelines for animal identification, including data transmission methods and reader specifications. The working frequency is 134.2Khz, and the data transmission modes are full-duplex and half-duplex, using frequency shift keying modulation and reverse non-return-to-zero coding.

　　In the large-scale pig farm in Shanghai, the breeding pig is fixed on an RFID ear tag shortly after birth or entering the farm. From then on, the pig will be tracked by the data network of the Shanghai Pig Safety Production Monitoring Platform to keep track of the breeding pig’s information. Important attributes, such as vaccination, weight, medical history, pedigree, etc. Inside the pig farm, staff use handheld devices to read RFID tags, record various production operations, and then transmit the data back to the host through the wireless communication network. At the same time, the handheld device will display the number of breeding pigs, breeding records and other related information, and provide some necessary operating suggestions under the guidance of the expert system.

　　Also in dairy farming, RFID tags are implanted in the stomachs of dairy cows. With the help of the RFID system, every time a cow enters the milking parlor, the reader can identify each cow according to RFID. On the milking controller, the output of each cow will be automatically recorded and analyzed automatically. Change, and get the milking performance, milking curve and health status of each cow. In addition, the precision and accuracy of feeding can be controlled by the combination of the RFID system and the automatic feeding system. Each time the cow eats, the system recognizes the identity of the cow and feeds the feed according to the pre-set formula.

　　RFID system performance advantages in animal husbandry management

　　The livestock management system based on RFID technology has the following advantages:

　　1. Inductive data collection is used, that is, the current information can be read out by simply shaking the collector on the ear tag attachment at the inspection point. The operation is simple and convenient.

　　2. The ear tag does not need wiring, it is easy to install, and the setting of coding and the increase and decrease of inspection points are also simple and convenient.

　　3. The system label has a unique ID code, which is durable, and the information cannot be tampered with or copied.

　　4. Intelligent tracking and management of each animal, the source animal can be traced as soon as an epidemic occurs, so as to achieve timely prevention and control, trace the root cause, and reduce the loss of the animal to the lowest point.

　　5. Informatization management, transparency, and timeliness, all levels of managers can simply manage through the network, and quickly and cheaply inquire about various feeding information.

　　In animal husbandry management, combining RFID technology, using RFID tags as the carrier, and using current computer network technology as a means, through identification coding, identification wearing, identification, information entry and transmission, data analysis and query, to achieve livestock from birth, slaughter The integrated whole-process monitoring to the consumption link is an organic combination of animal breeding, epidemic prevention, quarantine, and supervision, which not only achieves rapid and accurate traceability of animal epidemics, but also strengthens the entire management of livestock and poultry products from farm to table , So as to realize the scientific and institutionalization of animal husbandry and improve the level of animal husbandry management. Therefore, the application of RFID technology in animal husbandry management has great prospects.
