Removal of the caudae epididymides to create infertile boars for use in estrus detection programs.
Epididymectomies (removal of the caudae epididymides) were performed to create infertile boars. The simplicity of this procedure allowed for it to be easily performed on physically or chemically restrained boars that weighted 30 kg. Benefits of the use of epididymectomy, rather than vasectomy, to render boars infertile include low cost, simplicity, reduced surgical time, and minimum need of surgical instruments and materials. Epididymectomized boars are used in swine breeding management programs.
