[Amino acid in livestock and poultry applications, although there are still many areas to be improved, but is gradually maturing, and limited application research in aquatic products, China as the largest country in aquatic production, the largest country in the production of aquatic products, how to fish in The use of good amino acids is also of great significance. This seminar was fortunate to invite Dr. Gao Wen, the manager of the Aquatic Nutrition Program of the Health and Nutrition Division of Evonik Degussa (China) Investment Co., Ltd., to give a keynote speech at the conference: "Progress in the study of methionine in fish and shrimp feed", below The content was compiled by Dr. Gao Wen on the spot and was not confirmed by me. 】 Dr. Gao Wen used scientific experiments to analyze the value and role of methionine in fish feed and shrimp feed. Aquatic feed prices remain high, adding exogenous amino acids is the solution According to historical data, the change in the amount of fishmeal used in fishmeal has increased from 10% in 1988 to 35% in 2000. The price of fishmeal has increased more than five times from 1988 to 2012. In order to better improve the price of feed and meet the requirements of sustainable development, modern salmon feed continuously reduces the use of fishmeal. There are two ways to supplement amino acids. One is to directly add vegetable protein materials, and the other is to use The synthesized amino acids are added. Under the influence of the "amino acid bucket principle", the direct addition of crystalline amino acids has great advantages. The value of methionine instead of fishmeal in aquatic feed The substitution value of methionine was confirmed by the concentration gradient experiment of methionine instead of fish meal in the conventional feed of salmon, southern Chinese tilapia and northern squid, and South American prawn, and the specific proportion of substitution in the corresponding feed was provided. The value of methionine instead of fishmeal is reflected in two aspects: 1 the use of methionine instead of fishmeal has the meaning of cost saving under the same growth performance; 2 adding methionine instead of fishmeal is more beneficial to significantly increase the growth of water products under the same cost of addition. performance.
