8.1.2 What is the Return Of Investment of a vaccination with Enterisol® Ileitis?

In all the previous described trials, vaccinated pigs had significantly higher slaughter sales than non-vaccinated pigs. In a recently performed meta-analysis, combining the results of five trials, the difference in gross margin between vaccinated and non-vaccinated animals was calculated (Voets and Hardge 2006). The carcase returns per animal, based on the local carcase grading grid in the different countries, the local meat prices and costs for piglets and feed, were calculated. Vaccinated animals showed to have a significant higher gross margin of + 4.29 € than the non-vaccinated animals. See Table 8.1.2 a.

Economic return of Enterisol® Ileitis vaccination

This meta-analysis demonstrates that vaccination with Enterisol® Ileitis is profitable.
The individual gross margin of groups of vaccinated pigs on different farms can be higher
or lower than the outcome of this meta-analysis. The return of investment varies therefore from 2.5 : 1 to 5 : 1 and is depending on the farm-specific relation between vaccination costs and generated profit. Vaccination can reliably prevent losses due to a Lawsonia intracellularis infection and makes producing pigs a profitable enterprise.

Besides the direct economical benefits, the farmer has also many secondary management benefits from the vaccination against Ileitis.

These are:
  • Earlier shipment to grower/finisher barn or slaughterhouse
  • Higher throughput
  • Easier health management
  • Less culls and poor-doers to allocate to other groups or to hospitalise
  • More time between batches for hygiene clean-up
  • Increased uniformity
  • More animals in optimum grading grid
  • Reduction in the use of antibiotics
