For active immunisation of weaned pigs from 3 weeks of age and older to reduce the intestinal lesions caused by Lawsonia intracellularis infection and to reduce growth variability and loss of weight gain associated with the disease.
Under field conditions, the difference in average daily weight gain was seen to be up to 30 g/day when vaccinated pigs were compared to unvaccinated pigs.
Onset of immunity: as early as 3 weeks post vaccination.
Duration of immunity: for at least 17 weeks.
