3 Reasons Why Controlling Ileitis Through Oral Vaccination Just Makes Sense
Medicated feeds are often thought of as the answer to treating pigs infected with Lawsonia
intracellularis, the bacterium that causes ileitis. However, a growing body of research demonstrates that transitioning from dietary antimicrobials to a vaccination program can help reduce the impact of ileitis and deliver improved performance and reduced costs.1,2,3 The following three points illustrate the advantages that vaccination with Enterisol® Ileitis delivers:
1. Improved performance A recent Finnish – study tracked average daily weight gain of pigs vaccinated with ENTERISOL ILEITIS from the nursery through finishing phases. 1 At the end of the nursery phase, vaccinated pigs weighed an average of 2.65 pounds more than non-vaccinated pigs. At market, vaccinated pigs weighed an average of 7.94 pounds more than control group pigs.
2. Vaccines deliver ROI In a large-scale field – trial in Korea, nursery pigs vaccinated with ENTERISOL ILEITIS were observed to have significantly higher ADWG than the control group. That translated to a 4.2:1 return on investment from using ENTERISOL ILEITIS, and a $4.80per-pig higher gross margin.2
In addition, the cost of a vaccination program that includes the use of ENTERISOL ILEITIS was actually 50 cents per pig cheaper than a program including injectable antimicrobials, based on a study of pigs in the finishing phase conducted by Pipestone Veterinary Clinic. 3
3. Prevent rather than treat While – antimicrobials delivered in feed can help reduce the clinical signs of ileitis, they don’t promote immunity like a vaccine does. Vaccination also aligns with the ongoing industry shift away from the use of medicated feeds under the Veterinary Feed Directive. ENTERISOL ILEITIS is an excellent tool to help producers achieve the consumer-driven goal of reduced antibiotic use. Peiponen KS, Birger TT, Junnila JJT, Heinonen ML..
