Feed inducing agent for aquatic feed

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.

Description

Technical field: [0001] The invention belongs to the field of feed additives, in particular to an aquatic feed attractant. Background technique: [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 by the extensive use of plant protein. In addition, the growth rate and gastrointestinal health of aquatic animals 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 attrac...

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 , these two substances can promote food intake by stimulating the olfactory organs of aquatic animals, while nucleotides, amino acids, and alkaloids can promote food intake of aquatic animals by improving the taste perception of feed, but practice has proved that a single or simple effect on the above The mutual matching of substances can only have the effect of attracting food in a short period of time, and the effect of long-term use is not obvious

The main reason is that although the food intake increases after adding the above-mentioned food-inducing agent with food-attracting effect, it cannot improve the digestion and absorption of the feed, and the digestion and absorption of the vegetable protein itself in the feed is low, and excessive intake will lead to Indigestion, affecting the health of the digestive system, thus affecting the growth of aquatic animals
