medicine-Free Facility All Buckeye Nutrition brand feeds and supplements are milled at our 100 percent medicine-free facility in Dalton, Ohio. Cross-contamination is an important issue for horse owners and equine enthusiasts. Many plants mill both horse feed and other animal products, such as cattle or poultry feed. This is where cross contamination can take place. Ionophores or antibiotics can be beneficial for cattle, poultry or other livestock, but not for horses. The antibiotic monensin is highly toxic to horses. We do not manufacture any feed with medication. That means there are no antibiotics, ionophores or other medicines in the facility, so we eliminate the risk of cross contamination from production of medicated feeds. NO SHORTCUTS. At Buckeye Nutrition, we hold ourselves to higher standards, so you have peace of mind. We proudly maintain global certifications for quality. We are 100 percent equine focused. Combined with our 100 percent traceable ingredients, this means optimal nutritional formulation and delivery with zero risk of cross contamination from monensin. If you are looking for an ionophore-free, monensin-free and antibiotic-free feed, Buckeye Nutrition has it. Find a Buckeye Nutrition Dealer near you.
