Significant economic benefits were achieved by vaccinating pigs against ileitis in a trial conducted by Nottingham University’s vet school.
The study was carried out in Australia using over 4,000 pigs known to have clinical or sub-clinical ileitis. Half were injected with Enterisol Ileitis, a vaccine manufactured by Boehringer Ingelheim Animal Health.
Over 16 weeks (age eight to 22 weeks) the vaccinated pigs showed improved average daily liveweight gain, ranging from 30-150g per day, faster growth and reduced back fat. Mortality from ileitis was also reduced.
Dr Steve McOrist, of Nottingham vet school, said management practices on the three Australian farms were thought to be similar to those in the UK, particularly in relation to the keeping of uncastrated pigs on straw bedding, increasing the exposure of pigs to each other’s dung and, therefore, infectious agents.
