Biological Efficacy of DL-methionine and Liquid MHA-FA as Methionine Sources for Pigs
2001
Addition of DL-methionine or liquid methionine hydroxy analogue(MHA) to methionine deficient diet increased N retention in piglets and growing pigs and improved obviously the performance of piglet, which means that the efficacy was tested in a sensitive range. The efficacy of liquid MHA compaed with DL-methionine in pig was calculated to be 65%, which is lower than the DL-MHA content of 88% in the commercial product. Therefore, the results confirms previous extensive research in poultry on the biological efficacy of MHA in relation to DL-methionine,which was consistently found to be 65%.That is, the biological efficacy of liquid methionine hydroxy analogue (MHA) is only 65% in pig.
