The method is used for the determination of the mass fraction of methionine hydroxy analogue (DL-2-hydroxy-4-(methylthio) butyric acid (HMTBa) and its calcium salt) in fodder additives by capillary electrophoresis.
Currently, fodder additives containing HMTBa or its calcium salt, are presented on the market under such brand names as MHA®, Alimet®, Rhodimet®, and others.
For the determination of free methionine in fodder additives use the method М 04-63-2016 (Lumex Instruments set, order No 0300002780).
