Farm Animal Insemination Catheter Disposable PVC insemination catheters, supplied in packs of ten, sized for dogs through to sheep. The detail • PVC construction • Overall length 27.5 cm • Inner diameters 4 mm and 2.5 mm • Flexible along its length so it follows rather than forces • Tolerates chilled and warmed semen • White, single use, ten per pack Ten to a pack matters more than it sounds. These are single use, and a breeding programme gets through them faster than most people plan for. Important These are supplied as a general breeding consumable. They are not supplied sterile, no medical or veterinary claim is made about them, and no material grade is certified. Artificial insemination is a veterinary procedure. Get training from your veterinarian before attempting it, and have them handle any animal that is difficult to pass, bleeding, or showing signs of discomfort. Done badly, AI injures the bitch.
