DSM-Firmenich’s premix plant in Ames, Iowa, is has been certified for the production of its Hy-D premix products, under the U.S. Department of Agriculture (USDA) National Organic Program (NOP), the only organic regulation in the United States.
This certification enables the company 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 the 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.
