Workers must be able to move about quickly and with sufficient strength on rough terrain to restrain livestock for health care. Remotely-delivered injection systems can allow them to administer medication more easily. With any of the following Medication Injection Bows/Guns, livestock producers can vaccinate, medicate, or tranquilize an animal without having to first isolate and restrain it. Medi-Dart offers both crossbow and recurve bow projectile delivery systems that shoot retrievable 30cc-capacity syringes from distances of 30 feet and 20 feet, respectively. Cap-Chur offers air-fired rifle and pistol projectile delivery systems, carrying cases, fill-needle packs, and other accessories.
