Syringe needle for veterinary use and with livestock electric identification

A syringe needle for veterinary use and with livestock electric identification is formed by a pintle, a needle rod, the livestock electric identification, a one-way tube and a needle point, wherein the livestock electric identification is plugged into the needle rod close to the needle point through the needle point. Basic information and epidemic prevention or treatment information of the livestock are recorded into an electric chip through a reader-writer. When epidemic prevention or treatment is performed on the livestock, liquid medicine in a medicine bottle is pumped into a syringe through the one-way tube in the needle rod. During injection, by means of one-way passing ability of the one-way tube, the liquid medicine can be extruded onto cylindrical double antennas and the one-way tube when pushed, and the livestock electric identification can be injected into bodies of the livestock through the needle point from the needle rod.
