Six cases of rostral mandibular fracture with considerable displacement were treated successfully by external coaptation. Four cases were simple and two were compound fractures. After xylazine sedation and manual reduction of the fractures, the casting tape was laminated to make a rigid splint below the mandibles and then the splint was secured using the casting tape passing the nasal bridge and cranial and/or caudal to the ears as it encircled the head. During application of the tape, a PVC pipe 25 mm in diameter was held in its jaws to keep the mouth open so that the calf could suckle. Simple rostral mandibular fractures were cured after two weeks of cast immobilisation and compound fractures after about three weeks. This method is easy and non-stressful and provided a good prognosis in the present cases.
