Embodiment 1

[0014] Example 1 Salmon Growth Contrast Test

[0015] The composition of adult salmon feed and the weight percentage content of each component are: imported fish meal 22%, fresh fish paste 23%, krill meal 10%, fermented soybean meal 5%, active yeast 4%, soybean lecithin 2.5%, diphosphate Hydrogen calcium 2%, high-gluten flour 14%, medical stone 2%, multivitamin 2%, imported fish oil 12%, natural astaxanthin 1.5%.

[0016] Determination of amino acid composition and content in salmon muscle by amino acid automatic analyzer; determination of fatty acid composition and content in salmon muscle by gas chromatography-mass chromatography; determination of inosinic acid and guanylic acid content in salmon muscle by high performance liquid chromatography ;Comprehensive sensory evaluation is carried out from the aspects of fish body surface color, muscle taste, smell (fragrance and earthy smell), muscle density, etc. , Poor, 5 points to 1 point

[0017] Table 1 Comparison of growth ...

Embodiment 2

[0022] The composition of adult salmon feed and the weight percentage content of each component are: imported fish meal 18%, fresh fish paste 26%, krill meal 8%, fermented soybean meal 7%, active yeast 4%, soybean lecithin 3.5%, diphosphate Hydrogen calcium 2.5%, high-gluten flour 14%, medical stone 2%, multivitamin 2%, imported fish oil 10.5%, natural astaxanthin 2.5%.

[0023] The preparation method of fresh fish paste is:

[0024] The chilled miscellaneous fish was stirred and pulverized to reach 0.155mm after ultrafine crushing, and then treated with trypsin for 110 minutes, then concentrated in low-temperature vacuum and then filtered through an 80-mesh sieve to prepare fresh miscellaneous fish paste, in which the concentration of protease was 4500u / g . Fresh miscellaneous fish paste is mixed with other powdery raw materials, prepared, expanded and extruded, dried, and packaged to prepare fresh granular extruded feed for salmon.

Embodiment 3

[0026] The composition of adult salmon feed and the weight percentage content of each component are: 20% imported fish meal, 28% fresh fish paste, 9% krill meal, 5.5% fermented soybean meal, 4% active yeast, 3% soybean lecithin, diphosphate Hydrogen calcium 1.5%, high-gluten flour 14%, medical stone 1%, multivitamin 1%, imported fish oil 11%, natural astaxanthin 2%.

[0027] The preparation method of fresh fish paste is:

[0028] The chilled miscellaneous fish was stirred and pulverized to reach 0.160mm after ultrafine crushing, and trypsin and flavored protease (adding ratio 2:1) were added for 100 minutes, then concentrated in low-temperature vacuum and then filtered through an 80-mesh sieve to prepare fresh miscellaneous fish paste. The added concentration of protease is 4000u / g. Fresh miscellaneous fish paste is mixed with other powdery raw materials, prepared, expanded and extruded, dried, and packaged to prepare fresh granular extruded feed for salmon.

Abstract

The invention discloses a special fresh particle puffed feed for salmons and a preparation method of the feed. The special fresh particle puffed feed comprises the following components by weight percent: 10%-22% of imported fish powder, 13%-28% of fresh fish pulp, 8%-10% of krill powder, 5%-15% of fermented soybean meal, 3.5%-6% of active yeast, 2.5%-3.5% of soybean lecithin, 1.5%-2.5% of monocalcium phosphate, 10%-16% of high-gluten flour, 1%-2% of medical stone, 1%-2% of multi-dimensional multiple ore, 10.5%-12% of imported fish oil and 1.5%-2.5% of natural astaxanthin. The fresh particle puffed feed is prepared according to the conventional method for preparing the puffed fish feed. The special fresh particle puffed feed for the salmons is an ecological and environmental-friendly green fish feed; after the fish feed is fed to the salmons, the salmons have the advantages that the disease resistance is enhanced, the survival rate and the growth performance are obviously improved, the body color is obviously improved, the content of inosinic acid, the content of guanylic acid, the total amount of amino acid, the total amount of necessary amino acid and the total amount of unsaturated fatty acid and the like in main fresh substances of the salmons are respectively increased to different extents, the content of fat is obviously increased, and the indexes such as the muscle strength, the freshness, the fishy smell and the mouthfeel of the salmons are respectively and obviously improved.

Description

technical field [0001] The invention belongs to the field of aquatic feed processing, and relates to a special fresh granular puffed feed for salmon and a preparation method thereof. Background technique [0002] Salmon is a general term for salmon and trout. The meat is tender, delicious, smooth in taste, red or bright orange in color, with high nutritional value, rich in protein, unsaturated fatty acids, vitamins and various minerals. It is a popular dish on the table. People's favorite aquatic products. Salmon originally came from the Nordic waters, and they are widely cultivated in Europe, America and other countries, and most of them are cultured in sea water. At present, Shandong, Hebei, Heilongjiang, Gansu, Guizhou, Fujian, Beijing, Tianjin and many other provinces and cities in China use abundant cold water resources to breed salmon, and the economic benefits are considerable. Breeding species include Pacific salmon, coho salmon, Atlantic salmon, arctic whitefish, ...
