Humans have been using brands to recognize livestock animals for hundreds of years. In prehistoric times it was more of a ritualistic act. During the middle Ages in Europe, hot branding was used to identify the owner of livestock. This has sustained all the way through history. In the American West branding is often associated with trail drives and cattle rustlers. Electronic animal identification is a significant technology in contemporary animal husbandry offering immense benefits. Low-frequency applications are high-tech within the radio frequency classification of animals.
Ultra-high-frequency (UHF) submissions are appropriate for this purpose. Still, UHF systems have inadequacies through their defenselessness to metallic surfaces and liquids. Therefore, the reflection and amalgamation of electromagnetic radiation in the animals' environment is often challenging. Modern farming techniques dictate careful and accurate control of livestock, including the skill to tell apart individual animals. Livestock ear or recognition tags have been generally used to identify livestock for centuries. The use of identification tags has led to vast improvements in competence in agricultural industries, in addition to enhanced safety and lower costs to consumers because disease and genetic mutations are more easily identified with each improvement in the tracking of livestock.
There are many types of identification devices in use, such as rings, tattoos, and identification tags. The concluding ones are attached to the ear of the animal. Normally they include inkjet or laser markings which recognize, for example, the animal on top of the location where it was raised. EID tags are small “button-like” tags that are positioned in the ear. Each EID tag has an exclusive 15-digit number printed on it, and the number can also be read by scanning the tag with an EID reader. These tags are intended to last for the life of the animal. RFID's are commonly exploited for electronically identifying animals or objects. In many submissions, the transponder unit is laden with data and attached to an animal or object which is to be recognized.
An excellent application of non-powered RFID system is revealed for identification of animals in a meat-processing place. The reason for identifying individual animals in a meat-processing plant is for safety and sterilization reasons, and to perk up the meat quality and farming methods.
An ear tag typically carries an Animal Identification Number (AIN) or code for the particular animal or for its herd or flock which helps in tracing and finding the animal and to know the detailed information about the animal.
