The invention relates to a American eel adult feed which comprises the following components in parts by weight: the feed is prepared by mixing and crushing fish meal, wheat gluten, monocalcium phosphate, choline, citric acid, beer yeast, starch, compound vitamins and compound minerals, and adding the compound vitamins and starch into an obtained semi-finished product to obtain a finished product after mixing.

Description

American eel adult feed and preparation method thereof
Technical Field
The invention relates to the technical field of feeds, in particular to a American eel adult feed and a preparation method thereof.
Background
American eel is a fish belonging to the genus Anguilla of the family Anguillar Japonicae. The back was brown and the abdomen was dark yellow. It is very similar to european eels, but american eels have a much higher nutritional requirement than other eels.
At present, American eel feeds in the market mostly adopt Japanese eels and European eel formulas, the fish meal content is high, monocalcium phosphate is added, the feeds contain a large amount of nonabsorbable calcium phosphorus, eels cannot absorb the nonabsorbable phosphorus, and the nonabsorbable phosphorus is discharged into water, so that the environmental pollution is serious. Because the requirement on the viscosity of the feed is high, a large amount of starch is added into the feed, the proportion of fish meal and other nutrient substances is reduced, the American eels have low starch digestion utilization rate, and the incompletely digested starch is directly discharged into water, thereby seriously affecting the eel pond pollution discharge.
The American eel feed in the market has high nonabsorbable phosphorus content, inorganic phosphorus and calcium are added into the feed, and the unabsorbable phosphorus in the American eel is directly discharged into water, so that the environment is polluted.
The American eel feed in the market has high starch content, causes unbalanced nutrition of American eels, incomplete digestion of starch and fish meal, causes too high content of ammonia nitrogen and starch in water, and cannot reach the national sewage discharge standard.

Further, the fish meal has a VBN less than 80 and has strong affinity with starch.
Furthermore, the fish meal is uniformly mixed with 30 g of fish meal and 10 ml of water, and then stretched for 50 times, and the mixture after being stretched for 50 times also has viscoelasticity.
A method for preparing American eel adult feed comprises the following steps:
step S1, mixing fish meal, wheat gluten, sodium alginate, calcium dihydrogen phosphate, choline, citric acid, beer yeast and composite mineral, mixing, micronizing, wherein the fineness of pulverization requires 99.6% and sieving with 80 mesh sieve to form base powder,
and S2, feeding the base powder, the starch and the compound vitamins obtained in the step S1 into a mixing bin, and mixing to obtain the finished product of the American eel adult feed.
Furthermore, an ultramicro crushing belt axial flow cooling system is arranged in the mixing bin, so that the semi-finished product is guaranteed to be mixed with starch and vitamins at a low temperature; the axial flow cooling system of the superfine grinding belt ensures that the grinding temperature is below 45 ℃, the mixer can be rapidly cooled, and the temperature is below 30 ℃ when the mixer is mixed with starch.
(III) advantageous effects
The invention has the beneficial effects that: 1. the fish meal is processed from cod, sardine and armored fish, has a crude protein content of above 65% and a crude fat content of 8%, and is a main nutrient source for American eel.
2. The starch and the fish meal have affinity, the viscosity of the fish meal is mainly fish glue, and the sodium alginate can stabilize and enhance the viscoelasticity of the starch.
3. An ultramicro-crushing belt axial-flow cooling system is arranged in the mixing bin, so that the activity of the starch is not greatly influenced.
