A system for restraint and anesthesia in calves.

A mobile calf enclosure was developed which incorporated a hydraulic hoist and sling for the care of calves. This apparatus permitted induction of and emergence from anesthesia in an erect posture, which decreased the risk of aspiration and postoperative pulmonary problems. Fifty-two surgical procedures requiring general anesthesia have been performed on 29 calves during the last 2 years with only one operative death, and calves have been maintained within the enclosure for periods up to 1 month.
