Preparation method and application of nutrient solution based on insect extract

Abstract

The invention discloses a preparation method and application of a nutrient solution based on an insect extract. The preparation method comprises the following steps: S1, screening, cleaning and crushing insect living bodies; s2, centrifugally washing the crushed insect pulp, and separating the pulp and insect skin residues for later use; s3, performing decalcification and deacetylation treatment on the insect skin residues in the step 2, and extracting chitosan; s4, adding mannitol and a buffer solution into the slurry obtained in the step 2 in proportion to regulate the pH value, putting the regulated slurry into a water bath box, performing thermal change, and extracting SOD crude enzyme liquid; and S5, sequentially adding purified deionized water, chitosan and molasses into the SOD crude enzyme according to a weight ratio, uniformly stirring, and fermenting. The nutrient solution contains a large number of small molecule peptides and antibacterial peptides unique to insects, is rich in chitin, various trace elements, beneficial bacteria, enzyme preparations, animal and plant growth factors, vitamins, amino acids and the like, and can prevent various diseases, improve intestinal functions, improve production performance and improve meat quality and flavor.

Description

Technical field [0001] The present invention relates to the field of bio-culture technology, particularly to a preparation method and application of insect extract nutrient solution based. Background technique [0002] Aquaculture to include livestock and poultry rearing cattle, pigs, sheep, chickens, ducks, geese, rabbits, bees, due to market expansion, land and forage unable to make an adequate supply of fodder to feed into the mainstream. But relatively natural farming feed feeding fodder face some problems: such as digestion and absorption rate becomes low, poultry manure has become more smelly, poultry and livestock not only do not have adequate nutrition and immunity, are likely to cause disease. Inventive content [0003] To overcome the disadvantages of the prior art, an object of the present invention is to provide a preparation method and application of nutrient solution based insect extract. [0004] The present invention is achieved by the following technical measure...

AI Technical Summary

Problems solved by technology

However, compared with natural forage feeding, feed farming faces some problems: for example, the digestion and absorption rate becomes lower, and the manure of poultry and livestock becomes more smelly. Not only do poultry and livestock not get enough nutrition, but also their immunity is weakened, which is easy to induce diseases
