Aquatic feed attractant

Abstract

The invention provides an aquatic feed attractant. The aquatic feed attractant comprises, in a total percentage by mass of 100%, 40-50% of a yeast extract, 5-10% of dimethyl-beta-propiothetin (DMPT),20-30% of trimethylamine N-oxide (TMAO), 5-10% of bile salts and 10-20% of filler. By compounding a plurality of single attractants with the bile salts with the functions of promoting digestion, protecting the livers and promoting bile flow, the aquatic feed attractant has very good attracting and digestion-promoting effects on aquatic animals. Being added into aquatic feeds, the aquatic feed attractant provided by the invention is capable of effectively promoting digestion and absorption of feeds for the aquatic feed attractant contains the bile salts. The aquatic feed attractant provided bythe invention is high in safety, free of toxic and harmful substances and low in addition amount; moreover, the selected raw materials are stable and controllable in quality, so that the prepared aquatic feed attractant is wide in application ranges.

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 attracti...

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 attract 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
