\n

Quick answer:<\/strong> 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.<\/p>\n

Effectiveness<\/h2>\n

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.<\/p>\n
