Tail necrosis: A cause of tail biting?

摘要

Swine Inflammation and Necrosis Syndrome (SINS) is yet another influence factor associated with tail biting. Housing and management aspects including pen layout, stocking density, ventilation, feed and water supply and enrichment materials - from straw right through to chewing chains - have all been studied, and are still the focus of worldwide research. This research includes the ongoing work under the FareWellDock programme as described in recent issues of Pig Progress. FareWellDock protocols emphasise the crucial importance of alert stock surveillance and quality management, not only for early identification of aggression and biting problems but also towards ensuring the required quality of ventilation, feed, herd health and hygiene.
