Ischiopubic Symphysiotomy 6.
Delivery of the calf begins after the heifer has been cast in right lateral recumbency. This allows the hindlegs to spread and to angle forward which improves the angle of the pelvic inlet. Traction is applied to both legs which may be aided with the use of a calf puller, while the position and progress of the head are monitored intermittently.
