Method for culturing maggot by utilizing manure slurry

Abstract

The invention belongs to the technical field of animal manure comprehensive utilization and culture, and relates to a method for culturing maggot by utilizing livestock and poultry manure slurry. The method comprises the following steps: collecting animal manure in a temporary animal manure lagoon; fermenting effective microorganism (EM) strain, or enzymatic microorganism, or mixed strains of the EM strain and the enzymatic microorganism to ensure that the manure slurry is liquefied to form liquefied manure slurry; putting putrescent food in an outdoor fly concentrated position; putting collected seed maggot on a net chain above a fly cage to collect fly eggs and maggot; and maintaining the temperature of diluted manure slurry in a maggot culture pond, introducing oxygen to ensure that the maggot is cultured for 3 to 4 days and developed into imagochrysalis, and capturing by utilizing a net bag. The culture process has the advantaages of simple process, high animal manure utilization, safe and reliable equipment, high maggot culture benefit, large comprehensive utilization value, high quality of maggot and light environmental pollution, and can be used for large-scale industrial culture.

Description

Technical field: [0001] The invention belongs to the technical field of animal feces comprehensive utilization and breeding, and relates to a technical method for using animal feces, especially livestock and poultry feces slurry, to carry out fly maggot breeding, which can realize industrial and large-scale fly maggot breeding in vast rural areas. Background technique: [0002] Fly maggots have high nutritional value and economic value. The protein of fly maggots is high-quality protein, and the essential amino acid content in its crude protein is close to half of its total amount, which is comparable to fish meal. It can be widely used in the development of advanced nutrition, Aerospace food and medicine and other occasions. The artificial breeding of fly maggots originated in the late 1970s and early 1980s. So far, some developed countries have realized mechanized production of large-scale breeding of fly maggots; Farms mainly produce sterile fly maggots, which drive the ...

Problems solved by technology

The history of fly maggot breeding in my country began in the 1970s. It was generally a small-scale farming model, and it was mainly self-supporting and self-use; many patented technologies for industrialized fly maggot breeding in existing literature are all based on animal feces. The solid matter is mainly used as raw material for breeding. The technology of breeding fly maggots with these solid materials is difficult to be used in large-scale factory farming, and does not contribute much to the removal of non-point source pollution caused by livestock and poultry manure. The raised fly maggots are used as feed In addition, it is difficult to develop and process in depth; in conclusion, the existing fly maggot breeding technology does not use animal feces slurry for breeding, and the whole fly maggot breeding process is not easy to realize mechanized pipeline operation, it is not easy to improve labor hygiene conditions, and the labor intensity is high, and the discharge of three wastes is large. , the environmental protection effect is poor, and the production process is complicated
