Docking
Wednesday, 20 February 2008
Docking removes most of the lamb’s tail to prevent build up of dags on the wool around the sheep’s back end and thus avoid flystrike. Flies love to lay eggs in the dags hanging off the end of a sheep’s nether regions, the sheep become “blown” and the fly’s maggots eat the sheep’s flesh causing great pain and distress.
DO NOT USE AN UNHEATED KNIFE FOR DOCKING - IT IS NOT HUMANE AND INFECTION RISKS ARE GREATER. So, when should you dock lambs? The sheep code of welfare recommends that lambs not be docked before they have bonded with their mothers after birth – so give them at least 24 hours but do it before they are six weeks old. Method 1 - Rubber rings This is the preferred and easiest method, especially for lay people. The rings can be used to take the tail off at the same time as castration. Key points in docking with rubber rings: • Do it before the lambs are 6 weeks old.
• Lambs will experience pain for 10-20 minutes after ringing.
• If older lambs have to be docked, consult a veterinarian regarding the most suitable method and use of anaesthetic.
• Use a clean operating area (eg. movable temporary yards) to avoid build up of infection.
• Do not dock wet lambs or in wet weather to avoid infections.
• Leave enough dock on the lamb to fully cover the vulva.
• Cut the tail of male lambs the same length. Method 2 - Hot iron This is a wedge-shaped iron blade heated by gas, which can be used to both cut and cauterise the tail in one operation. The lamb is held in a sitting position and the iron is forced down on the tail laid out on the wood docking board. Key points in docking with the hot iron: • Do it before the lambs are 6 weeks old.
• Lambs will experience pain and struggle during the operation
• They show little distress afterward
• Make sure the tail is cauterised as it is cut. Don’t press on too hard to cut and not give time for cauterisation.
• After the operation, 2-3 seconds to make sure there is no bleeding.
• Don’t be tempted to dip the rear end of the lamb in a drum of dip. This soon becomes dirty and will do more harm than good.
• If older lambs have to be docked, consult a veterinarian regarding the most suitable method and use of anaesthetic.
• Use a clean operating area (eg. movable temporary yards) to avoid build up of infection.
• To avoid infections, do not dock wet lambs or in wet weather.
• Leave enough dock on ewe lambs to fully cover the vulva.
• Cut the tail of male lambs the same length. After care There should be few problems. Blowfly attack is the most likely and treatment with an appropriate spray will prevent this. Consult your veterinarian.
