The Board of Animal Health recommended dismissing the animals one day earlier than scheduled after six pigs in the 4-H show developed temperatures above 105 degrees.
Samples from the hogs sent home have been submitted to the Purdue Animal Disease Diagnostic Laboratory. Results won't be available for several days.
The pigs on Championship Row, the "World's Largest Male Hog" and the Champion Sow and Litter will still be on display. The Open Class breeding show will also go on as scheduled beginning with the Berkshire and Poland China breeds on Aug. 14.
No cases of human illness have been reported at the Indiana State Fair.
