preparation example Construction

[0029] The invention provides a preparation method of a biological feed additive rich in active peptides and beneficial bacteria, comprising the following steps:

[0030] Step 1, preparing beneficial bacteria seed liquid, adopting the method of mixing a single strain after fermentation or mixing and fermenting multiple strains at the same time, and carrying out aerobic or anaerobic fermentation at 20-40°C for 8-48 hours;

[0031] Step 2, prepare a nutrient solution, fully mix the nutrient components, add water to fully dissolve, and sterilize at 80-121°C for 10-30 minutes;

[0032] Step 3, solid-state fermentation, the beneficial bacteria seed liquid prepared in step 1, the nutrient solution prepared in step 2 together with the enzyme preparation are added to the solid-state fermentation raw materials and fully stirred and mixed. Under the ambient temperature of 5-40°C, Solid state fermentation for 12-96 hours;

[0033] Step 4, post-processing, drying the solid-state fermente...

Abstract

The invention discloses a biological feed additive rich in bioactive peptides and probiotics as well as a preparation method of the additive. The biological feed additive prepared with the method has the peptide content higher than 20%, the active probiotic content up to 1.0*10<9> cfu / g and contains fermentation metabolites such as bacteriocin and the like; meanwhile, the additive has the advantages that the additive is purely natural, non-toxic, harmless and free of pollution and residues.

Description

technical field [0001] The invention belongs to the technical field of biological enzymolysis and fermentation, and in particular relates to a biological feed additive rich in active peptides and beneficial bacteria and a preparation method thereof. Background technique [0002] Cottonseed meal, rapeseed meal, soybean meal, fish meal, wheat bran, corn, rice bran, etc. are commonly used feed industry raw materials. Cottonseed meal is mainly made of cottonseed, which is obtained by pre-pressing leaching or direct leaching to remove oil. Cottonseed meal contains about 42.5% crude protein, about 10.1% crude fiber, about 0.7% crude fat, and about 6.5% crude ash. Rapeseed meal is a by-product of oil extraction from rapeseed. It contains about 38.6% crude protein, about 11.8% crude fiber, about 1.4% crude fat, and about 7.3% crude ash. Soybean meal is a by-product obtained from soybeans after soybean oil is extracted. It contains about 43.0% crude protein, about 5.1% crude fibe...
