    This study introduces a fast and easy surgical technique for creating permanent rumen fistulae in livestock. The method uses a frozen cannula and requires minimal equipment, proving successful in sheep and cattle.

    Area of Science:

    • Veterinary Surgery
    • Ruminant Physiology

    Background:

    • Establishing permanent ruminal fistulae is crucial for research and clinical applications in ruminant animals.
    • Existing methods can be time-consuming, require specialized equipment, or have variable success rates.

    Purpose of the Study:

    • To describe a novel, rapid, and simple surgical technique for creating permanent ruminal fistulae.
    • To present a minimally invasive approach suitable for both sheep and cattle.

    Main Methods:

    • A frozen cannula is utilized, inserted into the rumen using a trocar-like technique.
    • The procedure is designed for speed and simplicity, requiring minimal surgical instrumentation.

    Main Results:

    • The technique successfully established permanent ruminal fistulae in all seven sheep and two cattle treated.
