Digital Intelligence, a new term that has emerged in recent years, has started to be applied in many fields, such as new retail, Internet, healthcare, education and many other industries, becoming an important part of the whole economic activity.To achieve "digital intelligence", not only need artificial intelligence, big data, cloud computing and other aspects of technological progress, but also need the construction of infrastructure, with hardware and software to achieve the Internet of everything.

Especially in the past few years in the field of animal husbandry, the concept of digital intelligence is highlighted, applied to all aspects, not only changed the traditional farming model, but also transformed the practitioners of new ideas about farming. In the original traditional farming model has a lot of problems, farmers do not have professional technical support for breeding, breeding enterprises can only rely on the eyes to see the hand to remember the stupid method of managing large farms, the government can not monitor the breeding situation in the region and so on.

The core of digital intelligence is based on massive big data, then combined with artificial intelligence, cloud computing, big data and other related technologies to open up the original data "end-to-end island", combined with the scenario to solve the actual problem.

In recent years, Chinese enterprises have successively launched a variety of digital intelligence service products applicable to the whole industrial chain of animal husbandry, such as digital beef cattle breeding management cloud platform, live cattle trading system, industrial information service platform, slaughter processing system, block chain traceability system, etc., as well as intelligent hardware equipment such as ultra-high frequency electronic ear tags, handheld reading equipment, intelligent weighing and grouping, intelligent environmental monitoring equipment, etc. 

The ear tag consists of two parts: the main tag and the auxiliary tag; the main tag consists of the main tag face, the tag neck and the ear tag head; the back of the main tag face is connected to the ear tag neck, and the ear tag head penetrates the animal's ear, embeds in the auxiliary tag and fixes the ear tag when it is used, and the ear tag neck remains in the perforation. The ear tag face contains the coding information.

The electronic ear tag applies RFID technology, with built-in chip and antenna, and the coding information is stored in the chip. Because RFID has the characteristics of non-contact, long-distance, automatic recognition of moving objects, readable and writable, some automatic measurement, measuring and quantification systems are promoted and used in the livestock industry. Livestock automatic weighing management system, milk production automatic measurement management system and other kinds of livestock raising and management system are based on the premise and basis of the use of electronic ear tag.

What is the significance of the ear tag?
People can track and monitor the whole process of animals from birth → slaughter → sale → consumer → final consumption end through the recognition function of electronic ear tag.

Comprehensively deepen the degree of digital intelligence of animal husbandry, change the traditional breeding mode, and promote the development of animal husbandry to new mode and direction.
