The new edition provides minimum and maximum recommended inclusion levels for fat-soluble vitamins (A, D3, E, K3) and water-soluble vitamins (B1, B2, B3, B5, B6, B7, B9, B12 and C). These recommendations span 18 species across 35 developmental stages, including poultry, swine, ruminants, equines, pets and aquaculture species.

According to Adisseo, the guide is built on three decades of scientific literature, enhanced by the company’s internal R&D findings and insights from global feed consultants and production partners.

Why Supplementation Standards Keep Changing

While no new vitamins have been discovered in the last half-century, Adisseo highlights that the optimal inclusion levels shift over time due to several factors:

• Faster animal growth rates and modern genetics

• Higher immune demands in antibiotic-free and reduced-antibiotic systems

• Climate-driven stressors such as heat stress, increasingly pressing in regions like Turkiye and the Middle East

• Processing intensity, as today’s pelleting and extrusion temperatures expose vitamins to higher degradation risk

• Meat quality objectives, which can be influenced by tailored vitamin levels

Quality Matters as Much as Quantity

The company emphasizes that performance depends not only on dosage but also on vitamin quality—covering fluidity, mixability, encapsulation, biological activity, and the control of potential contaminants.

Through its Microvit line and its Microvit Certification System, Adisseo reports continuous improvement of quality and consistency standards over the last 30 years, aiming to support both animal performance and sustainability across the protein value chain.

With technical teams operating in over 110 countries, Adisseo states that its experts remain available to assist feed producers in implementing the updated recommendations.
