Anti-bacterial peptide hydrolysate of earthworm and feed comprising the same

Abstract

The invention provides an anti-bacterial peptide hydrolysate of earthworm. The method for preparing the anti-bacterial peptide hydrolysate comprises the following steps: 1) collecting fresh earthworm, cleaning and drying; 2) hydrolyzing the earthworm after being processed in the step 1), brown sugar, water and preservative through water bath at constant temperature of 40-60 degrees centigrade for16-20 hours according to weight rate of 1: 0.2-1.1: 1-10:0.007-0.003; 3) filtering the impurities to obtain the anti-bacterial peptide hydrolysate of the earthworm. The anti-bacterial peptide hydrolysate of the earthworm provided by the invention comprises more than ten amino acids, digestive enzymes and small peptides which are suitable for aquatic animals. The anti-bacterial peptide hydrolysateof the earthworm is the mixture of multiple anti-bacterial peptides of the earthworm, multiple digestive enzymes and amino acids thereof, cooperates the pathogenic bacteria, has broad-spectrum antibacterial property, improves the feed utilization rate, reduces the feed / meat ratio, improves the immunity of the organism of the aquatic animals, promotes the growth of the aquatic animals, improves the quality of the aquatic animals, has simple production technology, and reduces the production cost.

Description

technical field [0001] The invention belongs to the field of animal food additives, in particular to an earthworm antibacterial peptide hydrolyzate. Background technique [0002] With the continuous development of the aquaculture industry, aquaculture failure is often caused by diseases and stress, which brings great economic losses to producers. Antibiotics are more and more widely used in aquaculture, which can prevent and control diseases, promote growth, and save nutrients. The application of antibiotics has effectively controlled the occurrence of many aquatic diseases, such as fish gill rot, enteritis, saprolegniasis, Chinese velvet sting edema, prawn limb rot, etc., which has greatly promoted the development of the aquaculture industry. develop. However, since the use of antibiotics is prone to produce drug-resistant strains, there are drug residues and the micro-ecological balance of aquatic animals is easy to destroy, making the prevention and control of aquacultu...

AI Technical Summary

Problems solved by technology

The invention has a certain antibacterial and antibacterial effect, but the production process is relatively complicated, and the production cost per unit potency is high

Secondly, the form of the product is a solid feed material, and the adsorption function of the vermicompost absorbs the special taste of the vermicompost, which affects its food-attractiveness

Thirdly, although it can be used in the production of feed mills, the pelleting and post-aging processes in the production process of preparing feed will reduce the antibacterial activity of antimicrobial peptides and the activity of digestive enzymes, thereby affecting its use effect
