Problems solved by technology

Nitrite is an intermediate product of bacterial nitrification and denitrification in the ecosystem. Normally, bacterial nitrification and denitrification in the ecosystem are in a dynamic equilibrium state, but with the intensification of water pollution, this balance It is easy to be broken, so that the content of nitrite in the environment continues to rise. The increase in nitrite concentration has become a major problem affecting t

Example Embodiment

[0027] Example 1:

[0028] A nutritional formula for preventing yellow river carp hemorrhage caused by nitrite in water, including the following components by weight: 0.03 parts of vitamin C, 0.004 parts of vitamin E, 0.001 parts of yeast zinc, 0.002 parts of yeast selenium, Ligustrum lucidum 0.06 parts of polysaccharides.

[0029] The fermentation trace element mixture containing yeast zinc and yeast selenium is first prepared, and the preparation method is as follows:

[0030] S1. Preparation of culture medium: According to 1L of alcoholic industrial yellow water, add 6g of urea, 2g of powder residue, 2g of bran, 2g of glucose, and 2g of sodium chloride to prepare a fermentation nutrient substrate, then sterilize at 121℃ for 20 min, and cool for backup. use;

[0031] S2. Select one of brewer's yeast, Lactobacillus subtilis, and Bacillus natto, and inoculate the recovered strains in the nutrient substrate prepared in step S1 at a ratio of 1%, and cultivate in the fermenter for 24-32...

Abstract

The invention discloses a nutritional composition for preventing cyprinus carpio haemorrhagic disease and a preparation method thereof, wherein the nutritional composition includes the following components in parts by weight: 0.02-0.04 part of vitamin C, 0.003-0.06 part of vitamin E, 0.001-0.003 part of yeast zinc, 0.002-0.005 part of yeast selenium, and 0.04-0.08 part of ligustrum lucidum polysaccharide. The preparation method comprises the steps: preparing a mixture of fermented microelements containing yeast zinc and yeast selenium, mixing the mixture of the fermented microelements with vitamin C, vitamin E and ligustrum lucidum polysaccharide, and thus obtaining the nutritional composition for preventing the cyprinus carpio haemorrhagic disease; 100 parts by weight of a feed containingthe nutritional composition for preventing cyprinus carpio haemorrhagic disease contains 0.1-0.5 wt% of the nutritional composition. Through addition of the fish nutritional composition in the range,the occurrence of the fish haemorrhagic disease caused by nitrite can be prevented, the occurrence of gill and body surface hyperemia is reduced, and the health of fish bodies is ensured; at the sametime, the growth of the fishes can be promoted, and the feed efficiency is improved. The nutritional composition has the advantages of convenience in use, low cost, good effect and the like.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a nutritional formula and a preparation method for preventing Yellow River carp hemorrhagic disease. Background technique [0002] At present, the aquaculture industry is developing extremely rapidly. Although it has brought significant economic and social benefits, high-density intensive farming and environmental degradation have caused increasingly serious environmental threats to aquatic animals. In production practice, environmental stress factors are complex and diverse, such as water quality deterioration and pollution such as eutrophication, heavy metals, etc., crowding stress, water temperature, low dissolved oxygen, etc. Nitrite is an intermediate product of bacterial nitrification and denitrification in the ecosystem. Normally, bacterial nitrification and denitrification in the ecosystem are in a dynamic equilibrium state, but with the intensificatio...
