Problems solved by technology

When enteritis occurs in fish, bleaching powder, sulfonamides, furans or a variety of Chinese herbal medicines are usually used to prevent and control, but the control effect is often not obvious or stable, or even ineffective, and the use of these chemical products or antibiotics leads to secondary pollution of water bodies , and even cause drug residues in aquatic products

preparation example Construction

[0027] The invention discloses a preparation method of a feed additive for reducing intestinal diseases of cultured fish, which comprises the following steps:

[0028] Step 1. Select fresh wet brewer's grains or dry brewer's grains, close the outlet of the mixer, and transport fresh wet brewer's grains or dry brewer's grains to the horizontal mixer through the auger;

[0029] Step 2, feed the molasses liquid into saturated steam and stir for 1-5 minutes, then add it into the blender that has loaded the brewer's grains, wherein, the amount of the molasses liquid added is 1%-5% of the weight of the brewer's grains (dry weight), usually Enter steam and adjust the material temperature to 15°C-35°C;

[0030] Step 3. Use 100°C-145°C high-temperature steam to wash and preheat the inner wall of the fermentation tank, transfer the temperature-adjusted material to the fermentation tank with an auger, and adjust the water content to 50%-70%;

[0031] Step 4. Add yeast and protease into ...

Embodiment 1

[0034] Select fresh wet brewer's grains, close the outlet of the mixer, and transport the wet brewer's grains to the horizontal mixer through the auger;

[0035] Put the molasses liquid into the saturated steam and stir for 2 minutes, add the molasses according to the proportion of 2% of the weight of the dried brewer's grains into the mixer that has been filled with the brewer's grains, feed in the steam, and adjust the temperature of the material to 35°C;

[0036] Use 125°C high-temperature steam to wash and preheat the inner wall of the fermentation tank, and transfer the temperature-adjusted materials to the fermentation tank with an auger;

[0037] Add steam sterilized and cooled tap water to adjust the moisture content to 60%;

[0038] Add the prepared yeast, the yeast is a commercially available Saccharomyces cerevisiae strain, the number of viable yeast bacteria is more than 20 billion CFU / g, and the addition amount is 1000g / ton of brewer's grains (dry weight); proteas...

Embodiment 2

[0042] Select fresh wet brewer's grains, close the outlet of the mixer, and transport the wet brewer's grains to the horizontal mixer through the auger;

[0043] Put the molasses liquid into the saturated steam and stir for 1 minute, add the molasses according to the proportion of 1% of the weight of the dried brewer's grains into the blender that has been filled with the brewer's grains, feed in the steam, and adjust the temperature of the material to 15°C;

[0044] Use 100°C high-temperature steam to wash and preheat the inner wall of the fermentation tank, and transfer the temperature-adjusted materials to the fermentation tank with an auger;

[0045] Add steam sterilized and cooled tap water to adjust the moisture content to 50%;

[0046] Add the prepared yeast, the yeast is a commercially available Saccharomyces cerevisiae strain, the number of viable yeast bacteria is ≥ 20 billion CFU / g, and the addition amount is 1000g / ton folded distiller's grains; protease, the protea...

Abstract

The invention discloses a feed additive for reducing intestinal diseases of cultured fishes and a preparation method of the feed additive. The preparation method comprises the following steps that wetbrewer's grains or dry brewer's grains are selected, a discharging port of a stirrer is sealed, and the wet brewer's grains or dry brewer's grains are conveyed into the horizontal stirrer through anauger; saturated steam is introduced into molasses liquid for stirring, then the mixture is added into the stirrer, steam is introduced, and the temperature of materials is adjusted; the inner wall ofa fermentation tank is washed and preheated by using high-temperature steam, the materials with adjusted temperature are conveyed to the fermentation tank through the auger, and water is added to adjust the water content of the materials; saccharomycetes and protease are added into the fermentation tank for fermentation enzymolysis; the fermented materials are sent to a fluidized bed for drying,the materials are conveyed into a crusher through wind, crushed and sieved, and the feed additive for reducing the intestinal diseases of the cultured fishes is obtained. The problem of antibiotic residues caused by antibiotic administration and the problems of complicated manual administration operation and the like can be effectively solved, the economic benefit is remarkable, and the social benefit is obvious.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and feed development, and in particular relates to a feed additive for reducing intestinal diseases of cultured fish and a preparation method thereof. Background technique [0002] Brewer's grains are the main by-products of beer brewing factories, containing cellulose, hemifiber and protein, and the total amount of cellulose reaches more than 45%. Because of high water content, large output, no proper treatment technology, and no good application channels, it is often discharged as waste or sold at a low price. Fresh brewer's grains are low in value and pollute the environment. [0003] Large-scale and intensive aquaculture spreads all over China, which is an important way to solve the protein food in our country. The traditional feed raw materials for ordinary freshwater fish only provide conventional nutrients such as protein, amino acid, energy, and cellulose. Fish have short intestines a...
