Green and safe insect feed, as well as preparation method and application thereof

Abstract

The invention relates to a green and safe insect feed, as well as a preparation method and an application thereof. The green and safe insect feed is composed of the following raw materials in parts by weight: 15-23 parts of konjac powder, 7-15 parts of a liquorice root extract, 11-19 parts of sunflower seed oil, 1-5 parts of calcium lactate, 23-31 parts of a seaweed extract, 0.1-1 part of sorbic acid, 4-8 parts of crab shell powder, and 0.5-2.5 parts of edible salt. The preparation method of the green and safe insect feed comprises the following steps of: weighing the konjac powder, the liquorice root extract, the calcium lactate, the seaweed extract, the sorbic acid, the crab shell powder and the edible salt according to the parts by weight, and carrying out mixing; putting the mixture into a superfine grinding machine so as to carry out crushing; adding the sunflower seed oil, and carrying out stirring so as to obtain a uniform mixture; and then, carrying out microwave treatment so as to obtain the green and safe insect feed. The insect feed disclosed by the invention can be improved in utilization rate, and has the effects of prolonging adult housefly oviposition time and increasing adult housefly oviposition amount; moreover, the insect feed is capable of improving survival rate and fecundity of peach borers. The insect feed is stable in original performance, long in shelf life, and capable of reducing insect production cost; moreover, the insect feed can be used for feeding various insect species and insects of different growth stages so as to provide guarantee for large-scale production of insects.

Description

technical field [0001] The invention relates to the technical field of insect feed, in particular to a green and safe insect feed and its preparation method and application. Background technique [0002] There are many kinds of insects with different shapes. They belong to arthropods in invertebrates. They are the most numerous animal groups on the earth. They account for more than 50% of all biological species (including bacteria, fungi, and viruses), and their traces are almost everywhere. every corner of the world. [0003] Musca domestica is an excellent animal protein feed, which has the advantages of strong fecundity, short life cycle, easy intensive production, and abundant feed sources. It is listed as the first new protein resource in the world. The rearing of housefly larvae and adults is a very important step in the production process of housefly. The low utilization of larval feed leads to poor economic benefits. The quality of nutrition of housefly adults dir...

Problems solved by technology

However, when the existing artificial feed is raised, not only the survival rate of the larvae is significantly lower than that of the natural host plant, but also the development is extremely irregular.

[0005] The existing feeds are basically aimed at a certain growth period of a specific insect, and have a single effect. Feeding a variety of insects requires many different types of feeds with different growth cycles, and the cost of feeding is high.
