Problems solved by technology

Since 2011, the disease mortality of Penaeus vannamei has been higher and higher, and the growth rate in most areas is below 20%. By the first half of 2012, the success rate of culture in Hainan, Guangdong and Guangxi has dropped to about 10%. Huge losses to the white prawn farming industry
The main reason is that there are more and more diseases of enteritis, white stool, and dry pancreas necrosis of artificially cultured Penaeus vannamei, especially the early death syndrome (EMS) that is spreading continuously in recent years has brought great harm to the culture of Penaeus vannamei. loss

Embodiment 1

[0028] As an embodiment of the present invention, the preparation method of the feed premix includes the following steps:

[0029] 1) Preparation of Chinese medicine extract:

[0030] Put 10kg of Purslane, 10kg of Agrimony, 10kg of Astragalus, 10kg of Radix Astragali, 10kg of Radix Glycyrrhizae, and 10kg of Licorice into a 1000L traditional Chinese medicine extraction tank, add 500L of water to it, soak for 1h and then raise the temperature to 100℃, then steam for 1h and filter to obtain filtrate; Then add 300L of water to the filter residue, cook at 100°C for 40 minutes, filter, and combine the two filtrates to obtain a Chinese medicine extract. Store the traditional Chinese medicine extract in a storage tank for later use.

[0031] 2) Prepare four kinds of viable bacteria respectively:

[0032] The preparation method of Lactobacillus plantarum viable bacteria liquid is as follows (take 1000L as an example): mix glucose 6kg, water-soluble starch 10kg, yeast powder 4kg, whey powder 4...

Embodiment 2

[0041] As another embodiment of the present invention, the preparation method of the feed premix includes the following steps:

[0042] 1) Preparation of Chinese medicine extract:

[0043] Put 15kg of Purslane, 10kg of Agrimonia, 20kg of Astragalus, 13kg of Radix Astragali, and 18kg of Licorice into a 1000L Chinese Medicine Extraction Pot, add 550L of water to it, soak for 1.2h and then raise the temperature to 100℃, then steam for 1.2h and filter to obtain Filtrate: Add 280L of water to the filter residue, cook at 100°C for 35 minutes, filter, and combine the two filtrates to obtain a traditional Chinese medicine extract. Store the traditional Chinese medicine extract in a storage tank for later use.

Abstract

The invention discloses fodder premix and a preparation method thereof. The preparation method comprises the steps that lactobacillus plantarum BW2013 strains, bacillus amyloliquefaciens A3 strains, bacillus substilis szx11 strains, rhodobacter sphaeroides WD-2 strains and baker's yeast are adopted as fermentation strains, a compound culture solution formed by compounding purslane extract, hairyvein agrimony extract, milkvetch root extract, humifuse euphorbia herb extract and licorice extract is adopted as a culture medium, fermentation is carried out, and the fodder premix with the effective viable count larger than or equal to 5*108 CFU / ml is prepared.

Description

Technical field [0001] The invention relates to the technical field of microbial application and feed premix preparation and processing, in particular to a feed premix for improving the immunity of Penaeus vannamei, improving intestinal diseases, and reducing early death syndrome of Penaeus vannamei and its preparation method. Background technique [0002] In 2005, my country’s total aquaculture area of ​​Penaeus vannamei was 1.5 million mu in freshwater and seawater, and by 2010 it exceeded 3 million mu, with an annual output of 900-1 million tons. As of 2012, Penaeus vannamei farming is no longer a specialty in the four southern provinces; it extends north to coastal areas such as Jiangsu, Zhejiang, Shandong, Hebei, and Liaoning, and has rapidly grown to more than 2.7 million mu, with an annual output of more than 1.5 million tons. Since 2011, the disease mortality rate of Penaeus vannamei farming has become higher and higher, and the growout rate in most areas is below 20%; b...
