If a boar is ill with a temperature and shows skin lesions, treat immediately and do not use for mating for a minimum period of four weeks. Alternatively, cross mate with boars that have no disease history or use AI. Vaccinate all gilts and young boars twice, two to four weeks apart (according to manufacturer's instructions) from 14 weeks of age. In herds where there is a high challenge it may be necessary to re-vaccinate gilts and boars so that a third dose of vaccine is given two months after the second often when the breeding animals arrive on the farm. Re-vaccinate sows either two weeks prior to farrowing, or at weaning time, depending on the incidence and history of disease on the farm. Make sure boars are re-vaccinated every six months. If disease breakdowns occur in spite of vaccination it is likely that the levels of challenge from the environment are high. Assess hygiene in breeding pens and move to an all-in all-out method of housing. In an outbreak remember that water, faeces, dung, nasal secretions, bedding and feed, harbour the organisms.
