Embodiment

[0024] A fish feed additive for preventing and treating skin diseases, the parts by weight (kg) of the raw materials are: crop straw 400, animal manure 50, fermented soybean meal 200, shrimp bran 150, grape seed powder 50, vegetable juice 30, garlic peel powder 20 , Tea polyphenols 0.03, salt 2, Kochia 2, Radix 2, Sophora 2, Cnidium 1, alum 0.3, pepper oil 40, sucrose ester 0.5, fructose 0.1.

[0025] The preparation method of the tea polyphenols is as follows: weighing a certain weight of fresh tea leaves, leaching in a boiling water bath for 30 minutes, filtering and removing slag, adding salt with a mass fraction of 5% to the obtained extract, and standing to precipitate for 1.5%. Centrifuge after 1 hour, discard the precipitate, keep the supernatant, adjust the supernatant to pH 10 with saturated lime water, let it stand for 1.5 hours and then centrifuge, discard the supernatant overnight, keep the precipitate, and use 5% The citric acid was dissolved, then extracted three...

Abstract

The invention discloses a fish feed additive used for controlling and preventing skin diseases, and a preparation method thereof. According to the preparation method, biogas anaerobic fermentation is adopted so as to change animal waste into biogas residue with utilization value; and the fish feed additive is obtained via further processing; waste is changed into valuables, reasonable utilization of animal waste is realized, the environment is protected, and culturing cost is reduced. According to the preparation method, biogas residue obtained via fermentation is subjected to mixing granulation and particle spraying, so that nutritional ingredients are enriched, unpleasant odor is changed, palatability is improved, and feeding attraction is improved. According to the preparation method, particles obtained via granulation are subjected to grease spraying, so that floatability of the particles in water is increased, it is convenient for ingestion of fish, dissolving of the particles in water is slowed, and utilization ratio is increased. According to the preparation method, raw materials such as fructus kochiae are added, so that bacteria, fungus, and parasites on the skin surface of fish can be killed, fish immunity is improved, infected wounded surfaces and damaged skin are treated, and rehabilitation of fish with diseases is promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fish feed additive for preventing and treating skin diseases and a preparation method thereof. Background technique [0002] On the one hand, with the intensification of water pollution, the incidence of fish skin diseases has risen sharply, and skin diseases have become one of the important factors leading to fish death. The skin is the first line of defense of the animal body. Once the skin is injured or damaged, it will often cause cross-infection of various pathogens, aggravate the disease, and then lead to the death of the fish. The types of fish skin diseases include viral skin diseases, bacterial skin diseases, fungal skin diseases and parasitic algal skin diseases. [0003] On the other hand, with the rapid development of animal breeding industry and the expansion of breeding scale, the pollution problem of animal manure has become increasingly serious. If it is no...
