Henderson Tool Castration Combines the Henderson Tool + A variable speed cordless drill + Newberry knife
Why was this method chosen? This method can be used on bulls of ALL ages Can be used on older & heavier bulls Quick and easy to perform Less traumatic than other methods Associated with less bleeding and swelling & risk of infection than other methods Since this is an older, more sexually mature bull, other methods may not be adequate to crush the spermatic cord
Pre-operative checklist: Disinfection of all tools (iodine+alcohol solution for 10 minutes) Restraint of bull in a chute (restrain the tail as well by tying it off to the side) Sedate the bull Give local anaesthetic (in the spermatic cord) Surgical scrubbing of the scrotal sac with chlorhexidine followed by surgical prep with alternating iodine + alcohol Sterile gloves on Ready to go!
How it is done: The testicles are pushed up the scrotal sac. The scrotal sac is then incised (side to side to facilitate drainage) with a Newberry knife. With the testicles now exposed, one testicle is grasped and 4 inches of spermatic cord is exposed. Clamp the pliers of the Henderson tool over the spermatic cord (proximal to the epididymis) Using the drill, rotate the tool, gradually increasing the speed until the spermatic cord is severed (app. 20 rotations) [Keep drill straight and in line with the cord] Repeat with the second testicle
