We are pleased to share an important milestone in our commitment to quality, transparency, and trusted manufacturing.

Our Ames, Iowa facility is now NOP-Certified for the production of our Hy-D® premix products, under the USDA National Organic Program (NOP), the only organic regulation in the United States.

This certification enables us to offer NOP certified ROVIMIX® Hy-D 62.5 and ROVIMIX® Hy-D 83.3 premix for customers, with specific sourcing or program requirements.

Achieving this certification required a rigorous multi-step process focused on how products are sourced, manufactured, and controlled. NOP certified Hy-D premixes are produced in accordance with NOP standards, including no irradiation, no sewer sludge, and no genetically modified organisms (GMOs).

Certification Highlights

• Hy-D® product options to support specific customer, program, or market requirements
• Additional flexibility to support multiple production systems and sourcing requirements
• Clear traceability and documented controls for certified product lines
• Continued access to our full Hy-D® portfolio, with all products NOP and non-NOP manufactured to the same high standards for quality, consistency, and performance

Hy-D® was the first 25-OH D3 on the market, has been proven in hundreds of research trials globally, and used in poultry for more than 25 years and swine for more than eight years. It delivers consistent performance and reliability across production systems worldwide. This certification expands our capabilities while reinforcing the proven performance, reliability, and trust customers have relied on from Hy-D® for more than two decades.

Please contact your account manager if you have questions or would like to discuss which Hy-D® solutions are the best fit for your operation.
