Owner Certification of market animals, with regard to the use of animal health aids, growth promotants or other livestock management substances is required. Please read and understand the following:

· Chemical substances used in livestock production, disease prevention or disease control, have approved withdrawal times.

· Information on specific use and withdrawal times can be found on product label instructions or printed drug lists available from my County Extension Office.

· Tranquilizers and other non-approved substances should not be used for food animals.

The withdrawal date for medication and legal drugs will be the date of animal check-in at the Butler County Fair.
