The present artificial insemination instrument may include a single use, hollow, elongate, metal pipette and a single disposable syringe that is not toxic to bovine sperm. The apparatus is used with any type of diluent that is not toxic to bovine sperm. In various embodiments, a technician may use non-sorted reduced sperm count semen straws from a bull stud, cut an unsorted semen straw into several pieces to use one piece at a time per cow, thaw one straw and mix the non-sorted semen with diluent, or use reduced sperm count semen straws filled with sex sorted semen by the manufacturer. A procedure is disclosed to use the artificial in semination instrument, reduced sperm count semen from any of the aforementioned sources, a non-toxic syringe, and a diluent to achieve conception rates at least as good as conventional prior art device and procedure conception rates.

Method and apparatus to reduce the number of sperm used in artificial insemination of cattle

An improved method, apparatus and kit for artificially inseminating a female bovine including a bellows-like container having an opening associated therewith for receiving a solution therewithin, a nozzle member having one end portion engageable with the opening associated with the bellows-like container, a hollow metal pipette having a closed terminal end portion for insertion into the reproductive organs of a female bovine, and a flexible tube member having one end portion engageable with the terminal end portion of the nozzle member and having its opposite end portion engageable with the proximal end portion of the metal pipette. The flexible tubing connecting the nozzle member with the metal pipette allows the bellows-like container to be elevated to a substantially vertical position prior to evacuating the semen/diluent solution from the bellows-like container through the present apparatus to the reproductive organs of a female bovine during the insemination process.

In the preferred embodiment, bovine semen is mixed with a 'suitable solution' to form an insemination medium which is injected into the reproductive organs of a female bovine to flood the uterine horns in a nonsurgical AI procedure. The invention includes an AI instrument having a disposable, single use pipette that may be used with this nonsurgical procedure. The AI instrument does not include a balloon and is referred to as 'catheter free'. Preferably, the uterine horns are flooded concurrently, but in the alternative, they may be flooded sequentially.

Artificial breeding techniques for bovines including semen diluents and AI apparatus

The present invention provides methods of producing biologically active recombinant bFSH and methods of increasing reproduction in mammals, particularly bovine, using recombinant bFSH. Also provided are methods of producing single chain recombinant bFSH. The recombinant bFSH of the present invention increases superovulation, embryo development, and reproductive efficiency in cattle and other ungulates.
