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.

[0040] Preferably, the main active ingredient...

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...

Abstract

The invention discloses feed capable of effectively preventing and treating a fish liver and gall syndrome. The feed comprises the following raw materials in parts by weight: 20-35 parts of rapeseed dregs, 10-20 parts of soy bean pulp, 5-15 parts of rice bran, 6-10 parts of cottonseed meal, 6-8 parts of wheat middling, 4.5-6 parts of fish meal, 10-25 parts of DDG-corn brewer's grain or mixture of DDG-corn brewer's grain and brewer's grain, 1-3 parts of calcium hydrophosphate, 1-3 parts of colza oil, 1 part of salt and 0.5-3 parts of premix, wherein the premix comprises compound vitamin, complex phosphoesterasum, allicin and seaweed meal. The feed disclosed by the invention has the following benefits: the nutrition is complete and balanced, health and no residue are realized, the fish immunity can be enhanced after the feed is used, the fish diseases are obviously reduced, especially the fish liver and gall syndrome, and the fish death rate are reduced; the cultivated fish has a natural body form and excellent quality and taste, avoids short and thick phenomena and can be resistant to long-distance transportation; the feed is high in conversion rate, excellent in the water resisting property, less in water dissolution loss and strong in ability of degradation, and does not pollute water.

Description

technical field [0001] The invention relates to the field of biological breeding, in particular to a feed for effectively preventing and treating fish hepatobiliary syndrome. Background technique [0002] In existing fish breeding, the mode of raising fish immunity by adding nutrients to fish is usually adopted. For example, Chinese patent 201010201756.4 (CN101869227A) discloses a compound feed for tilapia, which uses the addition of vitamins and minerals to improve the disease resistance of the fish, protect the intestinal tract of the fish, and prevent the occurrence of diseases. [0003] In the process of feed preparation, it is inevitable to produce miscellaneous bacteria. Especially Aspergillus flavus and Aspergillus parasiticus. During the growth of Aspergillus flavus and Aspergillus parasiticus, aflatoxin is a secondary metabolite produced by Aspergillus flavus and Aspergillus parasiticus, and it is a highly toxic and highly toxic substance. The hazard of aflatoxin ...
