| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Efficacy of 2-hydroxy-4-methylthiobutanoic acid compared to DL-Methionine on growth performance, carcass traits, feather growth, and redox status of Cherry Valley ducks.[Pubmed:29850886]
Poult Sci. 2018 Sep 1;97(9):3166-3175.
The objective of this study was to compare the bio-efficacy of 2-hydroxy-4-methylthiobutanoic acid (DL-HMTBA) with that of DL-Methionine (DLM) as sources of methionine in terms of the growth performance, carcass traits, feather growth, and redox statuses of Cherry Valley ducks. Six hundred and thirty male ducks were randomly allotted to 9 dietary treatment groups with 7 replicates of 10 birds each. The first group received a basal diet (BD) without methionine addition that was deficient in the total number of sulfur amino acids. In Groups 2 to 5 and Groups 6 to 9, the BD was supplemented with 4 increasing doses of methionine as either DLM or DL-HMTBA. The trial was run from ages 1 to 42 d. Dietary supplementation with DLM and DL-HMTBA improved body weight gain and feed intake as well as weights of carcasses, breast meat, and feathers compared with the BD. No significant difference was observed between the 2 methionine sources on growth performance, carcass traits, and feather growth. Concentrations of some redox markers in the pectoralis major muscle were improved by addition of methionine to the BD. However, a significant difference was observed between DLM and DL-HMTBA in this respect, as the supplementation of DL-HMTBA significantly increased the total antioxidant capacity, the activities of glutathione peroxidase, and the concentration of reduced glutathione in the pectoralis major muscle, compared with DLM. No significant difference between methionine sources was found with regard to the concentrations of oxidized glutathione and malondialdehyde in the pectoralis major muscle. Both DLM and DL-HMTBA increased malondialdehyde concentrations in the pectoralis major muscle compared with the BD. In conclusion, these results indicated that DLM and DL-HMTBA have equal biological value for the growth performance, carcass traits, and feather growth of Cherry Valley duck. Moreover, the improved antioxidant capacity observed with DL-HMTBA makes this a better candidate than DLM for lowering the oxidation process in the meat during post-mortem storage and thereby contributes to a better duck meat quality.
