Area of Science:

  • Veterinary Surgery
  • Reproductive Biology

Background:

  • Ovarian tissue collection is crucial for cell culture and reproductive research.
  • Existing methods for obtaining ovarian structures may have limitations in cost or invasiveness.

Purpose of the Study:

  • To describe and evaluate a practical, inexpensive surgical technique for collecting active ovarian structures (ovaries and corpora lutea) from cows for cell culture.
  • To assess the morbidity associated with the described surgical procedure.

Main Methods:

  • Unilateral ovariectomy per vagina was performed on 17 dairy cows (34 ovaries).
  • Bilateral ovariectomy was performed on 9 dairy cows (18 ovaries).
  • Corpora lutea were removed from 11 beef cows (13 corpora lutea) using colpotomy with three instruments.

Main Results:

  • The surgical technique was successfully employed for collecting ovaries and corpora lutea.
  • No cows exhibited clinical illness post-operation.
  • A low incidence of adhesions (9/37 cows) involving uterine horns and body was observed.

Conclusions:

  • The described surgical technique for ovariectomy and corpora lutea removal is practical, cost-effective, and associated with low morbidity.
  • This method provides a viable approach for obtaining ovarian tissues for cell culture in cattle.
