[0005] The current problems with insect processing methods are: the processing method is not mature enough, one is simple rough processing, such as simple crushing and then used as a feed additive; in addition, there is a method of extracting antimicrobial peptides, but the process is complicated and the steps are cumbersome. , and the amount of extraction is small, the yield is low, about 1.2%, it can be seen that the active ingredients of insects have not been effectively utilized, resulting in high cost or waste of resources

Embodiment 1
[0034] The insect additive for livestock and poultry feed consists of the following components by weight: 39 parts of insect protein powder, 1 part of chitin and antibacterial peptide.
[0035] The preparation method of described chitin and antimicrobial peptide is: comprise the steps:
[0036] a. first mix the dry worms according to the ratio. The dry worms include locusts, Tenebrio molitor, and fly maggots.
[0037] b. The above-mentioned dry insects are crushed and passed through a 20-mesh sieve.
[0038] c. Put the crushed insect powder into it, carry out high temperature and low pressure carbon dioxide supercritical extraction, and then sequentially separate to obtain chitin and antibacterial peptide, obtain fat, and obtain insect protein powder; the extraction pressure is 8 MPa, and the extraction temperature is 90 ℃.
[0039] d. The obtained chitin and antimicrobial peptide are used to compound insect additives for livestock and poultry, which consists of the followin...

Abstract
The invention belongs to the technical field of insect feed additives, and particularly discloses an insect additive for poultry and livestock feeds and application of the insect additive. The additive comprises the following components in part by weight: 20 to 50 parts of insect albumen powder, and 1 part of chitin and antimicrobial peptide. The chitin and the antimicrobial peptide which are extracted from insects are used for compounding the additive for the feeds, and the quality of the feed is improved, so that the quality of raised animals is effectively improved, and safe and healthy meat and fish or egg products are produced.
Description
technical field [0001] The invention belongs to the technical field of insect feed additives, in particular to an insect additive for livestock and poultry feed and its application. Background technique [0002] Insects are rich in antimicrobial peptides, chitin, immune proteins and other substances, which have attracted more and more attention, and some of them have been industrialized, and they are only crushed and used for feed as a rich source of protein; or just extracted Antimicrobial peptides are used for medicinal purposes, etc., but the extraction yield is relatively low and the process cycle is long. At present, commonly used insects include locusts, Tenebrio molitor, fly maggots, grubs, etc. [0003] Chitin: also known as chitin, chitin, and chitin, exists in lower organisms in nature, especially in arthropods. For arthropods, it is mainly crustaceans, such as shrimps, crabs, etc., containing up to 58% chitin. %-85%, but its source is limited and the extraction c...
