Don't Ignore Ileitis Control

Pig farmers agree: Losing a market hog hurts.

There are not many topics over which all pig farmers in the U.S. would agree, but two things over which they would agree are first, that no one likes dead pigs; and second, the worst type of dead pig is a market-sized pig.

Death loss in market hogs is frustrating for farmers. It’s difficult to move a market-weight dead pig out of a pen, and it’s also a significant loss in feed, labor, and animal health expenses when a pig goes on the compost pile instead of the truck.

Since all producers agree with these points, all producers need to have an ileitis plan in place the day a weaned pig arrives at their farm.

About Ileitis
Ileitis breaks generally occur in the weeks prior to and around the time of marketing. They manifest as both sudden death loss in good animals; and fall out, pallor, and brown to red or black stools in the general population. Ileitis generally has significant costs in loss of pigs, medication of remaining animals, and changes to marketing plans to accommodate treatment plans and withdrawal periods. In general, Ileitis breaks are some of the most costly disease issues I see regularly in the finishing period.

Tools are availableBIVI_Prevention-controlling-ileitis
The good news is there are many tools available for prevention of ileitis. These tools fall into two categories. The first is prevention via vaccination. There are two efficacious vaccines on the market for effective ileitis control. The second plan is a medication-prevention strategy.

Medication plans are generally not my first choice for ileitis prevention. Based on research out of the Pipestone Applied Research (PAR) barn, medication plans are not as cost effective. In addition, with the pressure on the industry to be responsible when using antibiotics, it is difficult to justify significant use of medically important antibiotics when excellent vaccines are available.

Having said that, I do believe there is a time and place for the use of preventative medication plans.

Preferred strategies
My first recommendation is to use a vaccine strategy. Both vaccines, in my clinical experience, and from the Pipestone Applied Research (PAR) data, are efficacious. There are pros and cons to each.

The BIVI Enterisol ileitis vaccine has been on the market the longest. It is extremely easy on labor to complete the vaccination process, as it is run through a water medicator. The person vaccinating the barn does need to be educated on the product and does need to follow certain protocols to make sure the product reaches the pig in an appropriate state. Because the product is a modified live vaccine, it cannot be run through the medicator at a time when there are any antibiotics in either the feed or water. There must be a non-medicated window in which to administer the vaccine.

parporcilisThe Merck Porcillis ileitis product is newer to the market. It is administered via a 2cc injection in the neck. Although the product requires more work in terms of labor, it does not require a non-medicated window in order to administer product.

Depending on the facilities, care givers, health status and a range of other factors, producers tend to choose one vaccine over the other and stick with it. My field experience is that both are very effective.

Don’t leave the door open
Despite the excellent tools available for mitigation of ileitis concerns, I am still involved with diagnosis and treatment of dozens of Ileitis cases each year. Those cases are extremely costly to the caregiver and owner of the pigs.

If you don’t have an ileitis prevention plan in place at your finishers, please work with your veterinarian to develop one. Leaving the door open to such a costly and preventable pathogen is ill advised.
