Embodiment 1
[0035] A feed for effectively preventing and treating fish hepatobiliary syndrome, comprising the following raw materials in parts by weight:
[0036] Rapeseed meal 20~35, soybean meal 10~20, rice bran 5~15, cottonseed meal 6~10, secondary meal 6~8, fish meal 4.5~6 and DDG-corn brewer's grains or DDG-corn brewer's grains and brewer's grains Mixture 10~25;
[0037] Calcium hydrogen phosphate 1~3, rapeseed oil 1~3 and salt 1;
[0038] Premix 0.5~3.
[0039] The premix described therein comprises multivitamins, compound enzymes, allicin and seaweed powder, and the ratio is 1:1~3:1~3:1~3. The compound enzyme used can effectively help the fish body to decompose food, reduce the burden on the intestinal tract, and improve the conversion efficiency of feed. Allicin can effectively kill bacteria in fish, and can effectively inhibit the growth of Aspergillus flavus and Aspergillus parasiticus during the production and storage of feed.

Embodiment 2
[0063] On the basis of Example 1, the fish feed also includes biological peptides 1 to 3 in parts by weight, and the biological peptides are mixed small peptides consisting of 12-50 amino acids (effective content 25% molecular weight< 5000, the parameters are the same below). The N-terminus contains lysine (~25%), arginine (~35%) and histidine (~40%), and the C-terminus is rich in alanine (~45%) and glycine (~55%). %), while the middle part contains proline (~30%).
[0064] The effect of adding biological peptides is:
[0065] 1. Physical and chemical properties: high temperature resistance, 100°C heating for 10-15 minutes still maintains activity; isoelectric point > 7, strong resistance, stable physical and chemical properties.
[0066] 2. Biological activity: Anti-Gram-positive bacteria, Gram-negative bacteria, fungi and viruses, using the membrane structure of microorganisms as the target, will not produce drug resistance, and have no residue. Rapid sterilization, low m...
Embodiment 3
[0068] On the basis of Example 1 or 2, the premix also includes at least 3 kinds of probiotics in photosynthetic bacteria, yeast, bacillus, lactic acid bacteria, nitrifying bacteria, denitrifying bacteria and Bdellovibrio . Preference is given to photosynthetic bacteria, lactic acid bacteria, nitrifying bacteria and Bdellovibrio bacteriophages. The yeast can also be obtained from DDG-corn brewer's grains and brewer's grains.
[0069] In Example 2, the biological peptide can relatively increase the nutritional content of beneficial bacteria by inhibiting the growth of harmful bacteria in the intestinal tract of fish, thereby improving the utilization rate of feed. In this example, by increasing the number of beneficial bacteria, harmful bacteria are inhibited, nutrition is strengthened, and the immunity of the fish is improved, thereby improving the growth of the fish. The combination effect of this example and Example 2 is better, but, because of the inhibitory effect of bio...
