Abstract
Aim:
Vasectomy is performed in deer for population control,
maintain pedigreed animals and prevent inbreeding. Conventional
procedure of vasectomy required a long-term anesthesia and longer
duration of hospitalization, which often result in stress,
morbidity and mortality. A study was conducted to capture, neuter
and release the deer with minimal hospitalization and stress by
adopting three finger palpation technique of vas deferens and
performing vasectomy through a key-hole incision.
Materials and Methods: The study was conducted on three
spotted male deer and three sambar male deer, which were
immobilized with a mixture of xylazine at the dose of 1.00 mg/kg
and ketamine at the dose of 5.00 mg/kg. The vas deferens could be
palpated as a piece of cooked spaghetti at the neck of the scrotum
on the anterior aspect by three finger palpation technique and was
able to fix the vas deferens between the thumb and middle finger.
Through a key-hole incision of <5 mm length, the vas deferens was
exteriorized and resected using electrocautery and the skin
incision was sealed with methyl methacrylate. The deer were
released on the same day, and no post-operative complication was
noticed.
Conclusion: The study revealed that three finger palpation
technique of vas deferens provided guidance for easy access to vas
deferens for vasectomy in deer with less hospitalization, and the
deer could be released on the same day.
Keywords: anesthesia, immobilization, ketamine, sambar deer,
spotted deer, three finger palpation technique, vasectomy,
