Over-the-counter antimicrobials disappearing
The days of simply picking up an antimicrobials at the feed mill to be used in the feed or water will soon be gone. Growth promotion and nutritional efficiency labels on medically important antibiotics will be removed by December 2016.
To date, bacitracin, mecadox, narasin, bambermycin and tiamulin are the only antimicrobials that will remain available to purchase over-the-counter for growth promotion. All other swine antibiotics used for disease prevention, control and treatment used in the feed will require veterinary feed directive or a veterinarian prescription for use in water.
