Special premix for farming Hermetia illucens

Abstract

The invention belongs to the technical field of Hermetia illucens feeds and particularly relates to a special premix for farming Hermetia illucens, which is made from 55-70 parts of fermented corn flour, 5-8 parts of a micro-ecological preparation, 3-5 parts of a complex enzyme preparation, 2-4 parts of a compound vitamin, 1-2 parts of minerals, 1-2 parts of an emulsifier and 0.5-1 part of a drying agent; the premix is added in an amount of 2-5% to kitchen waste (added in a pretreatment step of pulping or mixing of the kitchen waste) so as to feed Hermetia illucens. The growth and survival experiments on Hermetia illucens prove that the premix can effectively promote the growth of Hermetia illucens and remarkably increase the survival rate of Hermetia illucens after being added to kitchenwaste. The premix according to the invention can promote the absorption and utilization of nutritional ingredients by Hermetia illucens so as to increase the growth speed of Hermetia illucens, and canalso effectively reduce ammonia gas generated by Hermetia illucens in the process of converting kitchen waste, thereby avoiding the influence of the ammonia gas on the growth of Hermetia illucens andincreasing the survival rate of Hermetia illucens.

Description

technical field [0001] The invention belongs to the technical field of black soldier fly feed, and in particular relates to a special premix for black soldier fly breeding. Background technique [0002] Black soldier fly, English name Black soldier fly, belongs to Arthropoda (Phylum Arthropoda), Insecta (Class Insecta), Diptera (Order Diptera), Soldier Fly (Family Stratiomyidae) insects, body length is 13mm to 20mm and the overall color is black. The black soldier fly has a total life cycle of 42 days, which consists of a 3-day egg form, a 15-day larval form, a 14-day pupal form, and a 10-day adult form. Black soldier fly larvae can feed on organic waste, such as kitchen waste and livestock and poultry manure, and transform the organic waste into insect feces and highly nutritious insect bodies. Insect manure is a natural organic fertilizer. The insect body contains high protein and high energy. It can not only be directly used as feed for aquaculture to reduce the cost of...

AI Technical Summary

Problems solved by technology

[0003] The existing black soldier fly breeding usually feeds the kitchen waste directly to the larvae. Due to the complex composition of the kitchen waste and the incomplete nutritional content, it cannot meet the overall nutritional needs of the black soldier fly, and it is also not convenient for the larvae to eat. It is conducive to the digestion and absorption of larvae, thereby reducing the treatment efficiency of food waste, restricting the growth rate of larvae, and affecting the yield and quality of insect protein

At the same time, during the feeding process of black soldier flies, the feces discharged by them contain more nitrogen-containing organic matter, which will lead to an increase in the concentration of ammonia in the feeding environment of black soldier flies, and the decayed organic matter in the kitchen waste will also decompose A large amount of ammonia gas is produced. Excessively high concentration of ammonia gas will not only affect the survival of the black soldier fly, but also not conducive to the operation of the breeders during the breeding process.

In addition, when a large number of black soldier flies feed intensively, it is easy to cause a large amount of heat in the breeding. Excessive heat generation will endanger the survival of black soldier flies.
