Description
Technical field
The invention belongs to feed additive fields, and in particular to a kind of aquatic feeds phagostimulant.
Background technology
In recent years, since the shortage of fish meal resource, fish meal prices are made friends with all the way, Feed Enterprise is had to using raising feed
The dosage of middle vegetable protein substitutes the dosage of part or all of fish meal to reduce feed cost, but so has led to new
The appearance of problem, a large amount of due to vegetable protein use to affect flavor, the palatability of feed, in addition, due to plant egg
It is white there are anti-nutritional factors, digestibility are low, cause aquatic livestock the speed of growth and gastrointestinal health by bad shadow
It rings.
Presently found aquatic feeds phagostimulant has amino acid, alkaloid, TMAO (trimethylamine oxide), DMPT (dimethyl-
Thiopropionate) and nucleotide etc., wherein trimethylamine oxide, the phagostimulating effect of DMPT are relatively good, both substances can pass through thorn
The olfactory organ for swashing aquatic livestock, to promote to ingest, and nucleotide, amino acid, alkaloid then pass through the sense of taste of improvement feed
Impression promotes ingesting for aquatic livestock, but it was verified that it is single or simply interworking is carried out to above-mentioned substance can only be in the short time
Phagostimulating effect is inside played, long-time using effect is not obvious.Although its reason is main or addition is above-mentioned to have phagostimulating effect
Phagostimulant after, although food ration increases, but can not improve digesting and assimilating for feed, and vegetable protein itself in feed
Digest and assimilate low, excess intake can lead to indigestion instead, influence the health of digestive system, to influence aquatic livestock
Growth.Therefore, the water that aquatic feeds are digested and assimilated can be improved again by how developing a kind of phagostimulating effect that can improve aquatic feeds
Produce hot spot of the feed eating belt agent at research.
Invention content
The object of the present invention is to provide a kind of environmental protection of quality stability, security and aquatic feeds phagostimulants easy to process.
The aquatic feeds phagostimulant of the present invention, which is characterized in that based on total mass fraction 100%, including yeast extract
40~50%, DMPT (Dimethyl-propionic acid thetin) 5~10%, TMAO (trimethylamine oxide) 20~30%, bile salt 5~
10%, filler 10~20%.
The yeast extract, is preferably prepared by the following method：
Per 10L quality beer saccharomycete, after filtering, removal of impurities, de- suffering reason, centrifuged in supercentrifuge, rotating speed is
4000r/min centrifuges 30min, papain 50000IU, trypsase 100000IU is added after centrifugation in thalline, anti-
Insulation reaction in room, temperature is answered to control at 45 DEG C, react 24 hours；Temperature is then improved to 95 DEG C, then insulation reaction 2.5 is small
When, 2 kilograms of rice bran is added, is then spray-dried, the rotating speed of shower nozzle of spray drying is 15000r/min, and inlet temperature is 250 DEG C,
Outlet temperature is 110 DEG C, and negative pressure 90mpa packs to get to yeast extract after cooling down the yeast extract of gained.
The filler, preferably rice bran meal.
The aquatic feeds phagostimulant of the present invention is prepared by the following method, by all raw materials according to its mass percent
Be mixed evenly to get to the present invention aquatic feeds phagostimulant.
The present invention is compounded by a variety of single phagostimulants and with the bile salt for promoting digestion, hepatic cholagogic function, right
Aquatic livestock has good phagostimulating effect and promotees digestion effect.The aquatic feeds phagostimulant of the present invention is added to aquatic products to raise
In material, the bile salt contained can effectively facilitate digesting and assimilating for feed.The present invention aquatic feeds phagostimulant it is safe,
Without poisonous and harmful substance, additive amount is low, and selected material quality is stably and controllable, and product is widely applicable.
Specific implementation mode
