Content: 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. Killed vaccines are quite safe and have no adverse effects on the sow. Efficient storage of the vaccine as per the manufacturers recommendation is essential. Sporadic disease is common in sows but if one sow in a group becomes infected the exposure is high from her urine and faeces and it is advisable to inject all contact animals with penicillin. Birds can also contaminate feed. Assess the levels of the exposure in your herd.
