Cut costs with MetAMINO® and 65% bioefficacy

65 is the key to unlocking cost savings

MetAMINO® helps reduce feed costs by delivering more bioavailable methionine to livestock with fewer units of product. Thanks to its bioefficacy, demonstrated by numerous performance trials, just 65 units of MetAMINO® can replace 100 units of methionine hydroxy analogs – without compromising animal performance. This efficiency helps optimize feed formulation and supports more cost‑effective production.

Why 65 makes the difference: Comparing DL‑methionine and liquid MHA‑FA

This video explains the science behind the bioefficacy concept and why DL‑methionine is more efficient than liquid MHA‑FA. Learn how differences in purity, absorption, and metabolism translate into higher biological efficacy.

Bioefficacy: More savings with less product

Over 30 years of research show that 65 units of MetAMINO® can replace 100 units of methionine hydroxy analogs (MHA-FA) with no loss in performance. Thanks to the higher bioefficacy of DL‑methionine, less product is needed to achieve the same nutritional outcome. This efficiency helps producers reduce feed costs and improve profitability. With 100% bioefficacy, high purity, and reliable handling characteristics, MetAMINO® delivers cost‑effective methionine supplementation.
