Convincing a reluctant new dam to accept an orphaned or rejected lamb or kid can be tricky. Many strategies for “fostering” or “grafting” are frustration and too often unsuccessful. A technique called vagino-cervical stimulation (VCS), a.k.a. birth canal stimulation, can be helpful and increase the rate of successful grafting. The goal of VCS is to convince the ewe or doe’s
