Dr. Bill Hollis

How he saved the day in just 8 weeks1

When coughing, weaned pigs started leaving the farrowing barn for entry into the nursery, Bill Hollis, DVM, Carthage Veterinary Service, Ltd., knew something different had to be done on his client's 3,600-head Iowa sow farm.

It was clear this persistent SIV issue demanded an alternative strategy. Hollis recommended a strategic change to boost immunity: vaccinate the entire breeding herd with two doses of FluSure XP® 21 to 28 days apart.

"I was skeptical, but this strategy worked very well to stop the SIV activity. It eliminated coughing pigs, improved gilt health post-arrival and drastically improved overall pig quality in just 8 weeks," says Hollis."We went from an average post-weaning mortality of 12.6 percent to 4.4 percent."

According to the operation's production supervisor and on-farm manager, pigs were no longer coughing and were starting on feed better post-weaning.

Hollis thought about creating an autogenous vaccine, but going with FluSure XP was clearly the right decision. With two doses of FluSure XP, positive and consistent results were seen in the same amount of time it would have taken to create an autogenous vaccine.

"With smoldering SIV activity," says Hollis, "I now recommend swine veterinarians consider this alternative strategy to aggressively homogenize the sow herd's immunity to improve the quality of weaned pigs leaving the farm."

Now that the operation has SIV under control, the key to keeping the herd healthy is constant monitoring to make sure that young pigs stay SIV negative. For that, there's Flu DETECT® Swine.
