Like all of our products, our premix formulations are manufactured to the highest standards for product quality, safety, efficacy and traceability while meeting strict regulatory requirements. We continue to make significant investments in our facilities, our software applications and our people toward improving these products.  

Our premixes include: 
  • Custom trace mineral premixes
We have made custom trace mineral premixes for customers since 1980.  We can manufacture premixes to nearly any customer specification in either of our two custom blending facilities; Marion, Iowa and Omaha, Nebraska.
  • Selenium premixes
We make a variety of blended sodium selenite premixes to provide proper selenium supplementation to animal feed.  Selenium addition to animal feed is regulated by the US Food and Drug Administration. The mineral may be added to cattle, sheep, swine and poultry feeds at rates not to exceed 0.3 parts per million in the complete feed (total ration).
