Penile Translocation Surgery in Lateral Recumbency of a Calf Using Tilt-Up Mobile

This report evaluated the convenience and accessibility of a penile translocation surgery in the lateral recumbency of a calf using a tilt-up mobile compared with that of dorsal recumbency on the ground of a barn. One nine-month-old F-1 (Korean native sire x Holstein dam) calf was sedated with xylazine (0.03 mg/kg, IV) and restrained in the right lateral recumbency position on a tilt-up restraint mobile (90 cm high), whereas the other nine-month-old Korean native calf was administered xylazine (0.3 mg/kg, IV) and restrained in dorsal recumbency position on the ground of a barn, with assistance by one person. For the two calves, lidocaine was administered subcutaneously from the preputial orifice to the S-shaped penis. The preputial orifice was incised, and the preputial sheath and penis were separated bluntly, then laterally translocated to the site toward the left flank at a $40^{\circ}$ angle. Anti-inflammatory drug (ketoprofen) and antibiotics (penicillin) were administered following the surgery. The duration of surgery was 30 min shorter in the calf that received the surgery in lateral recumbency using the tilt-up mobile with operator's standing posture (60 min) than the one that underwent surgery in dorsal recumbency on the ground with operator's bending posture (90 min). One week after the surgery, the operation area, including the translocated preputial orifice, was healed without complications in both cases. The results detailed in this report demonstrate that penile translocation surgery in the lateral recumbency position using a tilt-up mobile might be used conveniently in calves due to the convenience of restraint, reduced surgery time, and reduced physical inconvenience for the surgeon.
