Electric ear tag for livestock raising

The invention discloses an electric ear tag for livestock raising. The electric ear tag comprises a tag body, a fixing hole, a bayonet and a first connection hole are sequentially formed in the tag body from left to right, a fixing pipe nail is inserted into the fixing hole, a threaded connection pipe is inserted into the upper end of the fixing pipe nail in a threaded manner, the lower end of thethreaded connection pipe is a metal threaded end, an intelligent box is fixedly mounted at the upper end of the threaded connection pipe, mounting grooves are symmetrically formed in two side walls of the bayonet, and the mounting grooves and the bayonet are jointly clamped with a solar cell. Through the bayonet, the mounting grooves and conductive screws, fixing firmness of the solar cell is improved; through an electrode cap and a connection bridge, the fixing pipe nail is locked on the tag, so that fixing firmness of the fixing pipe nail and an intelligent box is improved; through a positioning module and a wireless connection module, position information is located and sent in real time, so that convenience is brought to looking after livestock; the information is directly input directly through the wireless connection module, so that workload of information input is reduced.
