All parts are made of stainless steel. Up to 120 cuts on a single charge. Pocket model. Complete kit with one tail docker and a canister of lighter gas. During tail docking the tails of newborn piglets are burnt off and by this the vessels close simultaneously. Pathogens cannot penetrate when the vessels are sealed immediately. Generally tails are docked to a length of 2 – 3 cm. The reason for tail docking is to avoid cannibalism among pigs that might take place if tails remain long during rearing and fattening.
