Embodiment 1
[0021] The preparation steps of a kind of kelp probiotic fermented feed are as follows:
[0022] 1) Break fresh kelp, add 3 times the mass of water, add 10% mass of alginate lyase, start stirring, control the stirring speed between 180r / min-220r / min, and control the temperature at 30-35°C , After 30min-60min, the viscosity of the feed liquid is significantly reduced. After continuing the enzymatic hydrolysis for 2~3h, the enzymatic hydrolysis is completed, and the enzymatic hydrolysis kelp liquid is obtained.
[0023] 2) Add fermentation auxiliary materials to the enzymatic kelp liquid obtained in step 1). 1 kg of enzymatic kelp liquid corresponds to 0.3 kg of soybean meal, 0.3 kg of bran, and 0.4 kg of corn bran. Adjust the water content of the system to 50%. Stir evenly with the fermentation auxiliary material to obtain the fermentation mixture.
[0024] 3) Autoclave the fermentation mixture at 121°C, add Bacillus subtilis, Bacillus licheniformis, yeast and lactic acid bact...
Embodiment 2
[0033] The preparation steps of a kind of kelp probiotic fermented feed are as follows:
[0034] 1) Crush fresh kelp, add 2 times the mass of water, add 8% mass of alginate lyase, start stirring, control the stirring speed between 180r / min-220r / min, and control the temperature at 30-35°C , After 30min-60min, the viscosity of the feed liquid is significantly reduced. After continuing the enzymatic hydrolysis for 2~3h, the enzymatic hydrolysis is completed, and the enzymatic hydrolysis kelp liquid is obtained.
[0035] 2) Add fermentation auxiliary materials to the enzymatic kelp liquid obtained in step 1). 1 kg of enzymatic kelp liquid corresponds to 0.25 kg of soybean meal, 0.4 kg of bran, and 0.35 kg of corn bran. Adjust the water content of the system to 40%. Stir evenly with the fermentation auxiliary material to obtain the fermentation mixture.
[0036] 3) Autoclave the fermentation mixture at 121°C, add Bacillus subtilis, Bacillus licheniformis, yeast and lactic acid bac...
Embodiment 3
[0045] The preparation steps of a kind of kelp probiotic fermented feed are as follows:
[0046] 1) Break fresh kelp, add 4 times the mass of water, add 12% mass of alginate lyase, start stirring, control the stirring speed between 180r / min-220r / min, and control the temperature at 30-35°C , After 30min-60min, the viscosity of the feed liquid is significantly reduced. After continuing the enzymatic hydrolysis for 2~3h, the enzymatic hydrolysis is completed, and the enzymatic hydrolysis kelp liquid is obtained.
[0047] 2) Add fermentation auxiliary materials to the enzymatic kelp liquid obtained in step 1). 1 kg of enzymatic kelp liquid corresponds to 0.4 kg of soybean meal, 0.25 kg of bran, and 0.35 kg of corn bran. Adjust the water content of the system to 45%. Stir evenly with the fermentation auxiliary material to obtain the fermentation mixture.
[0048] 3) Autoclave the fermentation mixture at 121°C, add Bacillus subtilis, Bacillus licheniformis, yeast and lactic acid ba...
