Wenger Feeds makes thousands of different feed formulas for poultry and swine. Given the needs and markets of a diverse customer base, we offer a variety of choices including the inclusion of supplements and medications to treat disease.
To ensure the integrity and safety of our products, the production and delivery of all feeds is carefully sequenced. Sequencing involves creating an order within the manufacturing and delivery process to insure feeds with restricted ingredients are not manufactured directly before feeds for a species that may have a reaction to minute traces of medications or other ingredients from the previous load. Certain drugs require flushing between loads, and if proper sequencing for any ingredient cannot be accomplished with the existing workload, milling equipment is flushed with a small amount of feed or chopped corn. If flushing is not possible, mill operators physically clean out equipment and transition points to remove feed residue. Transportation equipment is flushed with a small amount of feed. Flushing can halt production and interrupt the efficiency of the mill, so every effort is made by mill operators and dispatchers to properly sequence whenever possible.
Proper flushing and sequencing procedures primarily ensure the safety of feeds. Medications that can remedy a disease in one species could potentially cause production drops and even mortality in another. Drugs are color coded on production and dispatch screens so their status is immediately apparent to operators and dispatchers. In total, six colors are used to represent different drug types, and their prohibited combinations are listed within the sequencing procedure. If drugs in different categories are used in combination, the most restrictive color code is used to sequence the order through the mill and delivery.
With the exception of the Massey, Maryland location, which does not use these medications, all of Wenger Feeds’ milling locations are registered and licensed by the Food and Drug Administration (FDA) to handle Category Two, Type A medications. In addition to licensing, the mills undergo inspection by the FDA, carefully track medication usage, and are required to submit feed samples throughout the year to insure proper usage.
While the procedures described above protect the integrity and safety of all feeds, additional flushing and final feed testing are services also available to customers to meet the specific needs of their customer base.
