Method for producing protein feed by using pig manure to breed black soldier fly larvae

Abstract

The invention discloses a method for producing a protein feed by using pig manure to breed black soldier fly larvae. The method comprises the following steps: firstly, separating pig manure from pig urine, and adjusting the moisture content of fresh pig manure to be 70%-80%; placing black soldier fly larva eggs in an incubation box added with mixed feed, incubating, and keeping feeding to the ageof 3 days; placing the 3-day-old larvae into a treatment tank according to a proportion, carrying out ecological cultivation on the larvae in the pig manure in the treatment tank, and growing the black soldier fly larvae into mature larvae after 10-15 days of cultivation; placing a larva collecting barrel at the edge of the treatment tank, allowing a part of the aged larvae to enter the larva collecting barrel for collection, screening pig manure residues in the treatment tank, separating residual larva bodies from the pig manure residues and combining the residual larva bodies with the blacksoldier fly larvae in the larva collecting barrel; carrying out high-temperature steam sterilization, drying and crushing on the collected black soldier fly larvae to obtain the protein feed. The protein feed is widely used for breeding livestock pigs, can also be used for breeding chickens and ducks, can further be used for aquaculture, and is wide in application and high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of breeding and utilization of black soldier flies, in particular to a method for producing protein feed by breeding black soldier flies with pig manure. Background technique [0002] The black soldier fly is an insect of the Diptera Soldier family. Its larvae are scavenging and have a wide range of food. They can live on rotting plants, kitchen waste, animal carcasses, and feces. They are an important link in the food chain in nature. The expansion of the pig industry, the strengthening of intensification and scale, and the continuous increase in the production of pig manure not only seriously affect the development of the industry, but also seriously affect the ecological environment around the breeding. Traditional composting takes a long time and is inefficient. Therefore, the use of pig manure to breed black soldier flies can not only convert the organic matter remaining in pig manure into its own nutri...

Problems solved by technology

Traditional composting takes a long time and is inefficient. Therefore, the use of pig manure to breed black soldier flies can not only convert the organic matter remaining in pig manure into its own nutrients, but also produce high-protein nutritional feed for black soldier flies. To realize the beneficial cycle of ecological agriculture, we propose a method of using pig manure to raise black soldier flies to produce protein feed to solve the above problems
