The present artificial insemination instrument may include: a) a single use, hollow, elongate, metal pipette and b) a single disposable syringe that is not toxic to bovine sperm. Other components may be added in alternative embodiments. The AI apparatus of the present invention is used with any type of diluent that is not toxic to bovine sperm in an amount determined by a Bovine AI Technician. In one embodiment, the present invention uses reduced sperm count semen straws from a Bull Stud, which is not sex sorted. In another embodiment, the Bovine AI Technician may cut an unsorted semen straw with about 20 million sperm into several pieces to use one piece at a time per cow, to effectively reduce the sperm count during insemination. In yet another embodiment, reduced sperm count semen straws may be filled with sex sorted semen by the manufacturer. In another embodiment the AI Technician may thaw one straw and immediately mix the non-sorted semen with enough diluent to inseminate two or more females. A procedure is disclosed to use a) the artificial insemination instrument, b) reduced sperm count semen from any of the aforementioned sources, c) a non-toxic syringe and d) a diluent to achieve conception rates at least as good as conventional conception rates with prior art devices and procedures. |
