Studies show a lower bioavailability for alternative methionine source relative to DL-Methionine in starter pigs
Methionine (Met) – an essential amino acid in pig diets to optimize performance – has been available mainly in two forms, DL-Methionine (99%) and liquid DL-Methionine hydroxy analogue-free acid (MHA-FA, 88%) for many years. Some years ago, however, the calcium salt of hydroxy analog of DL-Methionine (MHA-Ca, 84%) was re-introduced to the market as an alternative Met source for poultry and swine. This re-introduction generated questions about MHA-Ca’s biological effectiveness or relative bioavailability (RBV) compared with DL-Methionine as a Met source.
