Surgical contraception of free-ranging female capybaras: Description and comparison of open and minimally invasive techniques.

Objective: To develop, describe, and evaluate 2 surgical techniques for contraception of free-ranging female capybaras.

Study Design: Prospective study.

Animals: Cadaveric (n = 3) and free-ranging female capybaras (n = 21).

Vasectomy of golden-headed lion tamarins (Leontopithecus chrysomelas) using local anesthesia after sedation with dexmedetomidine-ketamine-meperidine.

The study evaluated the combination of ketamine, dexmedetomidine, and meperidine for vasectomy in golden-headed lion tamarins. Lidocaine infiltration was required for intraoperative analgesia and atipamezole was used at the end of the procedure. The protocol promoted satisfactory sedation and analgesia with a short recovery time in tamarins.
