Overview
MHA-FA / HMTBa Free Acid Feed Grade (Liquid Methionine Hydroxy Analogue, 88%) is a premium-quality product supplied by ZEAL BIOTECH under strict quality management with full batch traceability. The original liquid methionine source (Alimet/Rhodimet AT88-type): an L-methionine precursor converted in liver/kidney that supplies the first-limiting sulphur amino acid for growth, feathering, egg output and methyl metabolism in poultry/swine/aqua, with 88% methionine activity and 100% availability; its liquid form enables precise, dust-free, homogeneous spray addition at the mixer and large-scale mill automation, and as an organic acid it mildly supports gut hygiene. The isopropyl ester (HMBi) is the ruminant-protected version for dairy absorbable methionine.
