Embodiment 1

[0015] Embodiment 1: take 1 kilogram of sea cucumber feed as the base material and add in the container, add 1g bacillus subtilis, 20ml lactic acid bacteria, 0.5g saccharomyces, 5g glucose, 300ml purified water or sterilized water; utilize acetic acid to the above-mentioned feed Adjust the pH value to make the pH value reach 6.0; then seal and ferment for 12 hours at a temperature of 20°C.

Embodiment 2

[0016] Embodiment 2: take 1 kilogram of sea cucumber feed as the base material and add in the container, add 2g Bacillus subtilis, 50ml lactic acid bacteria, 0.8g saccharomyces, 10g glucose, 400ml purified water or sterilized water; utilize acetic acid to treat the above-mentioned feed Adjust the pH value to make the pH value reach 6.8; then seal the fermentation at a temperature of 35° C. for 24 hours.

Embodiment 3

[0017] Embodiment 3: take 1 kilogram of sea cucumber feed as the base material and add in the container, add 1.5g bacillus subtilis, 35ml lactic acid bacteria, 0.68g saccharomyces, 7.5g glucose, 350ml purified water or sterilized water; utilize acetic acid to The pH value of the above-mentioned feed is adjusted to make the pH value reach 6.4; then the closed fermentation at 26° C. for 18 hours is enough.

Abstract

The invention discloses a fermentation process of a sea cucumber compound feed, which comprises the following steps: 1-2g of bacillus subtilis at least with the concentration of 1010CFU/g, 20-50ml of lactic acid bacteria at least with the concentration of 109CFU/ml, 0.5-0.8g of yeast at least with the concentration of 1010CFU/g, 5-10g of glucose and 300-400ml of purified water or sterile water are added to a sea cucumber feed, and then acetic acid is used for regulating the pH value to 6.0-6.8; and fermentation is carried out for 12-24 hours at 20-35DEG C. The process is simple, the operation is easy, the production cost is low, and probiotics in the feed are increased, thus promoting digestion of nutrients that are difficult to digest, improving the palatability of the feed, enabling stichopus japonicus to grow rapidly and to have high survival rate and improving the water quality.

Description

technical field [0001] The invention relates to a fermentation process of sea cucumber compound feed, which is mainly to ferment the compound feed used during sea cucumber seedling cultivation and juvenile growth. Background technique [0002] At present, compound feed is widely used in the process of raising sea cucumber seedlings and larvae for direct feeding, but it often results in deterioration of water quality, low food intake, slow growth, and even disease spread, which seriously affects the development of sea cucumber aquaculture. Contents of the invention [0003] The purpose of the present invention is to provide a fermentation process of sea cucumber compound feed with simple process, low cost, no influence on water quality, increase of growth rate of sea cucumber and reduction of diseases, so as to overcome the deficiencies of the prior art. [0004] The fermentation process of the sea cucumber compound feed of the present invention is to add Bacillus subtilis,...
