Fencing
77. Most outdoor units now use electric fencing systems to create paddocks. These should be properly constructed and maintained, with an appropriate current to protect the security of the stock, to avoid animals leaving the site and to keep groups of animals apart. This is particularly important between groups of boars. Pigs easily learn to respect electric fences, but adequate training facilities should be provided. All fences should be checked at least daily and any problems such as slack or broken wires or earthing should be rectified immediately.
