The invention discloses an improved catheter for artificial insemination in animals, comprising primarily a simple improvement of the nozzle mounted at the front end of catheter. The nozzle is predefined on its peripheral surface with pores, channels, or indented texts or patterns of different shapes, which can be used to hold reagents, liquid medicine, ointment or lubricant for animals. As such, when the operator inserts the nozzle into the vagina of female animal body, the procedure achieves not only artificial insemination, but also other purposes, such as testing, experiment and treatment, thereby augmenting the usage and enhancing the efficiency of artificial insemination catheter.
