Adisseo releases updated vitamin guide covering 18 animal species

FRANCE – Adisseo has unveiled a significant update to its Microvit® Nutrition Guide (MNG), offering fresh vitamin supplementation recommendations for 18 species and 35 developmental stages in a move the company says is designed to help feed producers adapt to rapidly changing production environments. 

The updated guide, published this week, compiles findings from 30 years of scientific literature, Adisseo’s own research, and practical industry experience to redefine optimal vitamin use in modern feed formulations.

The new edition outlines minimum and maximum recommended levels for fat-soluble vitamins A, D3, E, and K3, as well as hydro-soluble vitamins B1, B2, B3, B5, B6, B7, B9, B12, and C. 

These guidelines apply to a broad range of species, including poultry, swine, ruminants, horses, pets, and aquatic animals.

“Everything is based on technical and scientific publications from the last 30 years, supplemented by Adisseo’s research in this area, and the practical experience of consultants and the feed industry,” the company said.

Responding to evolving production challenges

Adisseo’s update comes at a time when feed producers face increasing variability in raw material quality, more intensive heat treatments during feed processing, and shifting nutritional demands tied to faster growth rates and antibiotic-free production systems. 

These pressures, the company notes, have created new vitamin requirements, even though no new vitamins have been discovered in more than half a century.

Heat stress, in particular, has emerged as a persistent challenge for livestock and poultry producers across climate-vulnerable regions, prompting greater emphasis on micronutrient support for immune function and resilience. 

The guide highlights how specific vitamin levels can enhance not only animal health but also meat quality.

According to Adisseo, the need for updated supplementation frameworks has accelerated as feed mills adopt higher-temperature conditioning and longer retention times. 

These processes can degrade or reduce the availability of certain vitamins, making compensatory adjustments essential for maintaining performance.

Focus on quality and safety

The company also stresses that vitamin quality, not just quantity, plays a critical role in feed efficiency. Factors such as fluidity, mixability, encapsulation, and biological activity can influence how effectively vitamins perform in animals. 

Adisseo points out that contaminants must be closely monitored and controlled to safeguard the entire animal protein production chain.

“For more than 70 years we have focused on supporting the feed industry for improved animal performance,” Adisseo stated, adding that its Microvit® line and Microvit® Certification System reflect three decades of continuous improvement in vitamin quality control.

With the release of the updated Microvit® Nutrition Guide, Adisseo says it aims to provide feed producers with clearer, more adaptable vitamin recommendations that promote animal health, performance, and sustainability across diverse production systems.
