Problems solved by technology

[0003] With the rapid development of intensive and cage farming and the popularization of compound feed, the yield of perch has increased significantly, but its meat flavor has shown a downward trend, seriously affecting the quality of perch and industrial development.
In the artificial breeding of sea bass, there are generally phenomena such as unbalanced feed nutrition, low protein content, high fat content, and large-scale feeding, which result in reduced nutritional value of fish, unbalanced amino acids, high body fat content, poor taste, and abdominal fat. rate increase, induce fatty liver, cause disease in severe cases, etc.

preparation example Construction

[0030] The present invention also provides a preparation method of the feed, comprising the following steps: (1) pulverizing the fermented soybean meal, and mixing it with earthworm powder, fish meal, seaweed powder and shrimp shell powder to obtain powder;

[0031] (2) mixing the powder with lysophospholipids, olive oil, fish oil, lutein and water and then granulating to obtain feed embryos; the amount of water added is 7 to 16% of the mass of the powder;

[0032] (3) Expanding the feed embryos and drying them to obtain the feed.

[0033] In the present invention, the mixing in step (1) and step (2) is preferably carried out using a V-type vertical mixer, wherein the mixing time in step (1) is preferably 5 minutes, and the mixing in step (2) The time is preferably 7min.

[0034] In the present invention, there is no special limitation on the granulation method described in step (2), and conventional methods in the field can be used, and the particle size of the feed embryos ...

Embodiment 1

[0044] (1) 40kg fermented soybean meal is pulverized and crossed through a 60 mesh sieve, fully mixed 5min with 13kg earthworm powder, 15kg fish meal, 10kg seaweed powder and 24kg shrimp shell powder in a V-type vertical mixer to obtain powder;

[0045] (2) with 0.05kg lysophospholipid, 6kg olive oil, 0.9kg fish oil, 1kg lutein and 9kg water in V-type vertical mixer fully mixing 7min after granulation to obtain feed embryo;

[0046] (3) Air-drying the feed embryos to a moisture content of 6% after puffing.

Embodiment 2

[0048] (1) 35kg fermented soybean meal is pulverized and crossed a 60 mesh sieve, fully mixed 5min with 10kg earthworm powder, 25kg fish meal, 7g seaweed powder and 16kg shrimp shell powder in a V-type vertical mixer to obtain powder;

[0049] (2) with 0.15kg of lysophospholipid, 10kg of olive oil, 0.7kg of fish oil, 1.5kg of lutein and 14kg of water in a V-type vertical mixer fully mixed for 7min and granulated to obtain feed embryos;

[0050] (3) Air-drying the feed embryos to a moisture content of 8% after puffing.
