Efficient methionine supplementation

Proven MetAMINO® bioefficacy

Every trial in the ATLAS confirms that 65 units of MetAMINO® (DL‑methionine) achieves the same animal performance as 100 units of liquid methionine hydroxy analog free acid or its calcium salt. In practical terms, this means feed and livestock producers can significantly reduce their methionine consumption when switching from methionine hydroxy analog products to MetAMINO®, applying the 65% bioefficacy concept in everyday feed formulation.

For trial‑specific economic outcomes, please refer to the individual cost calculations provided with each study. To estimate your potential savings under your own production conditions, you can also use the MetAMINO® Calculator.

Cutting costs, loads, and CO₂: Unlock the power of 65

What if efficiency had a number? 65. With MetAMINO®, just 65 units can effectively replace 100 units of methionine hydroxy analogs – helping you cut costs, cut transport loads, and cut CO₂ emissions without compromising animal performance. Decades of research shows how the power of 65 unlocks smarter business decisions and a smaller environmental footprint. Discover how efficiency, profitability, and sustainability meet in one simple number.
