At present, China is in a serious period of African swine fever, and it is very important to effectively ensure the standardization of pig breeding management and pork food, among which ear tags play an irreplaceable role in the traceability management of pig farm management. As the front-end identification of the whole management process of pigs, ear tags can track and monitor the whole process of pigs from birth, slaughter, sales, consumers and final consumption in real time.

It is conducive to animal disease control. Ear tags can be used to manage the ear number of each pig with its breed, source, production performance, immune status, health status, livestock owner and other information, once the epidemic and animal product quality and other problems occur, you can track (trace) its source, distinguish responsibilities, plug loopholes, so as to achieve the scientific and institutionalized animal husbandry, and improve the level of animal husbandry management.

It is conducive to safe production. Ear tag is a large number of pig management to achieve a clear identification and detailed management of the tool, through the ear tag can enable breeding enterprises to find hidden dangers in time, quickly take corresponding control measures, to ensure safe production.

Improve the management level of the farm. In pig management, the identification of individual animals (pigs) is realized in the form of ear tags that are easy to manage, and the identification of individuals is realized by assigning ear tags with codes to each pig, and the ear tags used in pig farms mainly record data such as farm numbers, pig house numbers, and pig individual numbers. After the ear tag of each pig in the pig farm realizes the identification of the individual pig, the daily information management of the individual pig such as material management, immunization management, disease management, death management, weighing management, medication management, and slaughter records is realized through the reading and writing method of the handheld machine.

It is convenient for the state to supervise the safety of livestock products. A pig's ear tag code is carried for life, through this tag, can be traced back to the pig's production farm, acquisition field, slaughterhouse, pork sales flow to the supermarket, if it is sold to cooked food processing vendors, there will also be a record, such a identification function, is conducive to cracking down on the sale of a series of participants in the sale of sick and dead pork, supervise the safety of domestic livestock products, and ensure that the public eats healthy pork.
