Performance enhanced by technology.


Biolys® is an innovative lysine source with many advantages for animal nutrition. With Biolys® your animals will get a guaranteed effective feed diet – while lowering your enterprises’ ecological footprint.

The challenge of boosting efficiency

Reducing feed costs by balancing the amino acid composition in your livestock diet is a sound method to boost efficiency, but it requires precision. Lysine is an essential and limiting amino acid in feed for poultry, swine, fish, crustaceans and dairy cows. A lysine-deficient diet can have a negative impact on your animals’ growth performance.

The L-lysine source with added value

Biolys® is a highly effective and reliable source of lysine that enables unsurpassed precision in balancing amino acids. Biolys® has a higher proportion of L-lysine than typically contained in comparable products. It not only enables you to meet requirements for the essential amino acid L-lysine, but also contains valuable components resulting from its fermentation process – additional nutrients and energy that further benefit your livestock.

The result is lower feeds costs for pigs, poultry and aquatic species. Using Biolys® in a lysine-deficient diet significantly increases average daily gain (ADG). In addition, it helps reduce waste emissions through a higher feed conversion rate (FCR) for an improved environmental footprint.

Reduced groundwater pollution with Biolys®
Reduced groundwater pollution with Biolys®

Groundwater pollution due to livestock excretion is a growing concern. Biolys® is a key tool that enables producers to reduce the crude protein content of their feed. As a rule of thumb, for each percentage point reduction in dietary protein, the excretion of nitrogen in manure and ammonia emissions are reduced by nine percent. In addition, water consumption is also reduced, which leads to a total reduction of manure volume.

Biolys® moving towards climate neutrality

Biolys® is produced by means of fermentation. Microorganisms convert dextrose, a sugar derived from corn, into L-lysine. The mixture of lysine and biomass is the basis of the product – without any waste.

Regarding utilities, the production process requires water, steam and electricity. At our production sites in Blair (US) and Castro (Brazil), we meet 100 percent of the electrical energy demand by renewable sources. Both plants are located in the midst of corn-producing regions with favorable supply of corn derived dextrose. A huge part of the total production is sold in regional markets. Moreover, Evonik has put in further efforts to improve the carbon footprints of its Biolys® production. Since 2021, the emission from Evonik have been improved by ~20% leading to the lowest carbon footprint for lysine available in the market – and helps you improving the environmental footprint of your products.
