Problems solved by technology

[0004] At present, the antibiotics and disinfectants that are mainly used to prevent carp diseases caused by Aeromonas hydrophila have serious problems due to long-term use: (1) The abuse of antibiotics has resulted in enhanced drug resistance of bacteria, making it more difficult to treat fish diseases; (2) ) Chemical disinfectants have large toxic and side effects, strong local irritation, and carcinogenicity; (3) Pollution destroys the aquaculture water environment and reduces fish immunity; (4) Serious drug residues reduce the quality of aquatic products and endanger human health

Embodiment 1

[0025] Take 0.075 parts of copper, 0.88 parts of zinc, 0.36 parts of manganese, and 0.012 parts of xylanase, and mix them to prepare feed additive A1.

[0026] In order to verify the application effect of the present invention, the feed additive of the present invention was applied to carp (with a body weight of about 7g) in 7 fisheries in Sichuan, Fujian and Guangdong for testing. Divide carp equally into two groups, the experimental group and the control group. The diet of the experimental group is added with the above-mentioned feed additive A1 according to 0.5% of the total weight of the fish feed; the diet of the control group is the fish feed of the same weight without adding the additive A1 ; The two groups of fish were fed 6 times a day, the daily feeding rate was 5-6%, and the infection experiment was carried out after 70 days of feeding. Both the experimental group and the control group were injected with Aeromonas hydrophila, with 3 repetitions in each group, 55 fis...

Embodiment 2

[0036] Take 0.057 parts by weight of copper, 1.14 parts by weight of zinc, 0.31 parts by weight of manganese, and 0.008 parts by weight of xylanase, and mix them to prepare feed additive A2.

Embodiment 3

[0038] Take 0.070 parts by weight of copper, 0.93 parts by weight of zinc, 0.22 parts by weight of manganese, and 0.013 parts by weight of xylanase, and mix them to prepare feed additive A3.

Abstract

The invention discloses a fish feed additive, an application method, application and a feed containing the additive. The fish feed additive comprises the following components in parts by weight: 0.057-0.075 part of copper, 0.88-1.14 parts of zinc, 0.22-0.36 part of manganese and 0.008-0.013 part of xylanase. According to the invention, by adding the feed additive in the range, the specific and non-specific immune functions of fish are improved, the capacity against aeromonas hydrophila infection is enhanced, the immune protection rate is improved, and the death rate under infection is reduced; and moreover, without the substances causing toxic and side effects on fish body as well as antibiotic substances, the additive avoids pollution and drug resistance.

Description

technical field [0001] The invention belongs to the field of freshwater fish breeding, and in particular relates to a feed additive for freshwater fish, a use method, an application and a feed containing the additive. Background technique [0002] Fish products have high nutritional value, which is very important for improving dietary structure and improving human health. With the increasing awareness of health, consumers have higher and higher requirements for the consumption and quality of fish products. Carp is the main freshwater aquaculture fish in my country, accounting for 18-20% of the total fish aquaculture output. However, in recent years, with the continuous increase of breeding density and pollution of the breeding environment, the incidence of various fish diseases has increased sharply, among which bacterial sepsis is one of the serious diseases of carp. [0003] Aeromonas hydrophila is the main pathogenic bacteria of carp epidemic sepsis. The fungus is ubiq...
