Technical Field

The invention belongs to the field of livestock breeding informatization, and particularly relates to a method for quickly searching cattle applied to a pasture.

Background

At present, the cattle breeding is developed towards the large-scale direction, the number of cattle in each farm is large, in order to facilitate daily management, an ear tag is usually installed on each cattle, and the number on the ear tag is the number of the cattle. Although the ear tag is installed, it is difficult to find the target cattle among many cattle, and particularly, it takes a long time for the cattle with many cattle.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a method for quickly searching cattle applied to a pasture, and the time for searching a target cattle is shortened through the matching of an RFID tag and an RFID reader.

The purpose of the invention is realized by the following technical scheme: a method for quickly finding cattle applied to a pasture comprises the following steps:

step one, each cow wears an RFID tag storing the cow number corresponding to the cow;
