The Neogen Dr. Frank’s Calf Puller, developed by veterinary specialist B.N. Frank, DVM, is a precision instrument proven effective in thousands of calving cases. Its unique fetal extractor provides uniform tension to prevent slipping, while traction on the calf and counter-thrust on the cow assist natural birthing. The unit assembles easily in minutes, with unscrewing rods for simple storage and cleaning. Includes a 45" OB chain and is made in the USA.
