Quick answer: DL-methionine is a 99% pure powder, while methionine hydroxy analogue (MHA) is sold as a liquid (MHA-FA, about 88%) or calcium salt powder (MHA-Ca, about 84%). MHA is not methionine itself and is generally considered less effective per kilogram than DL-methionine, so feed mills compare products on cost per unit of effective methionine activity.

Effectiveness

Animals convert MHA into methionine, but most research and industry practice treat MHA as less effective per kilogram than DL-methionine. The exact relative value used varies by nutritionist and study, so always compare on equal methionine activity.

Which to choose?

DL-methionine: simple to store and mix, highest active content, ideal for most mills and farms.
MHA liquid: suits large mills with liquid dosing systems.

How should methionine sources be compared?

By cost per unit of effective methionine activity, not price per kilogram.
