Adisseo publishes Methiopedia technical reference book for methionine
Animal nutrition solution provider, Adisseo, is publishing a methionine reference book—Methiopedia-on the occasion of the start-up of its Rhodimet®AT 88 production plant in Nanjing, China.
"Being one of the first companies to have synthesised powder methionine in the 40s, we considered that it could be of great interest to collect all the scientific information that Adisseo has gathered in research studies, trials and customer experience" says Pierre Casamatta, Adisseo's global business director for methionine and sulphur products.
"Adisseo experts have compiled information on methionine from around the world, including the latest developments, from fundamental research to in-vivo trials performed both in independent experimental facilities and on commercial farms" he explains.
The book offers a complete description of the three forms of methionine - L-methionine (L-Met), D,L-methionine (D,L-Met) and D,L-methionine hydroxy (D,L-HMTBA) - with their characteristics and properties. General chemical processes, metabolism and utilisation of each form are detailed in the book. Methiopedia gives precise data on hydrolysis, absorption, and intestinal transport of these different sources.
Methionine exhibits additional functions in animals beyond protein synthesis. These functions have been studied by a number of research teams, including Mrs Rachel Martin-Venegas, University of Barcelona, Spain and J. Buyse, Catholic University of Leuven, Belgium, and are also explained in Methiopedia: cellular-signaling function, protein expression, acidification, antioxidant potential.
Besides physiological data, Methiopedia also provides a review of important animal performances including feed conversion and body weight gain, with practical diets including D,L-Methionine or D,L-HMTBA, especially for broilers. These recent data have been compiled from trials on animals conducted at different institutes across the world, such as BARC (Bangkok Research Centre) in Thailand; The China Agricultural University in Beijing, China; IRTA in Spain; INRA in France, as well as Adisseo's facilities (CERN - Centre of Expertise and Research in Nutrition in Commentry, France).
"These trials and their meta–analysis show new evidence of the biological equivalency of both forms," says Pierre Dalibard, global technical manager of Adisseo.
Furthermore, the technical aspects of incorporating D,L-Met or D,L-HMTBA in feeds are developed by Adisseo experts in Methiopedia. They detail the different parameters involved in dosing and mixing accuracy, up to recovery tests, to ensure that the required level of methionine is reached in feed for both powder and liquid forms.
Technical results of recent trials carried out by Adisseo are included in the appendix, which also contains a selection of abstracts or articles on methionine presented at the latest Adisseo Advancia Seminars, which have been bringing scientists and nutritionists from across the world together yearly to share research progress on sulphur amino acids since 2007.
