Problems solved by technology

[0002] In recent years, due to the shortage of fishmeal resources and the high price of fishmeal, feed companies have to increase the amount of plant protein in the feed to replace some or all of the amount of fishmeal in order to reduce the cost of feed, but this has led to the emergence of new problems , the flavor and palatability of the feed are affected due to the extensive use of plant protein. In addition, the growth rate of aquatic animals and the health of the gastrointestinal tract are adversely affected due to the presence of anti-nutritional factors in plant protein and low digestion and absorption rate
[0003] At present, the aquatic feed attractants found include amino acids, alkaloids, TMAO (trimethylamine oxide), DMPT (dimethyl-thiatin propionate) and nucleotides, among which trimethylamine oxide and DMPT are more effective in attracting food , th

Embodiment 1

[0015] Preparation of yeast extract:

[0016] Every 10L of high-quality brewer's yeast, after filtering, removing impurities and debittering, centrifuged in a high-speed centrifuge at a speed of 4000r / min, centrifuged for 30min, after centrifuging, add 50000IU of papain and 100000IU of trypsin to the bacteria. Heat preservation reaction in the reaction chamber, the temperature is controlled at 45°C, and the reaction is 24 hours; then the temperature is raised to 95°C, and the heat preservation reaction is continued for 2.5 hours, 2 kg of rice bran is added, and then spray-dried. 250°C, the outlet temperature is 110°C, and the negative pressure is 90mpa, the yeast extract is obtained, and the obtained yeast extract is cooled and packaged.

[0017] Based on the total mass fraction of 100%, yeast extract 40%, DMPT (dimethyl-thiatin propionate) 5%, TMAO (trimethylamine oxide) 30%, bile salt 5%, rice bran meal 20%, these The components are mixed and stirred evenly, and the aquatic...

Abstract

The invention provides a feed inducing agent for aquatic feed. The feed inducing agent comprises the following materials in percentage by total mass: 40-50% of yeast extract, 5-10% of DMPT (dimethyl-dimethylpropiothetin), 20-30% of TMAO (trimethylamine oxide), 5-10% of bile salt and 10-20% of filler. The feed inducing agent provided by the invention compounds multiple single feed inducing agents and the bile salt with functions of promoting digestion, protecting liver and benefiting to the gallbladder, and has good feed-inducing effect and digestion promoting effect to aquatic animals; the feed inducing agent for aquatic feed is added into the aquatic feed, and due to the contained bile salt, the digestion and the absorption of the feed can be effectively promoted; the safety is high, no toxic and harmful substances are contained, the added amount is low, the quality of the selected materials is stable and controllable, and the application range of the product is wide.
