Description

Efficient breeding feed for hermetia illucens and breeding method thereof
Technical Field
The invention relates to the technical field of organic matter resource utilization and hermetia illucens breeding, and particularly relates to a feed for efficiently breeding hermetia illucens and a breeding method thereof.
Background
The black soldier fly (Hermetia illucens L.), also known as Hermetia illucens, the rotten soldier fly can take feces of livestock and poultry and domestic garbage to produce high-value animal protein feed, and because the black soldier fly and the rotten soldier fly can reproduce rapidly, the biomass is large, the feeding performance is wide, the absorption and conversion rate is high, the management is easy, the feeding cost is low, the palatability of animals is good and the like, so that the black soldier fly and soldier fly are recycled, and the larva of the black soldier fly and soldier fly is called as a phoenix insect and becomes a famous resource insect such as fly maggot, yellow mealworm, barley pest and the like, and is popularized worldwide. The natural products are produced in America, are widely distributed all over the world at present, are introduced into China in recent years, and are widely distributed in Guizhou, Guangxi, Guangdong, Shanghai, Yunnan, Taiwan, Hunan, Hubei and the like. At present, the method is widely applied to the treatment of wastes such as chicken manure, pig manure, kitchen waste and the like.
The black soldier fly breeding technology is gradually applied to the treatment of kitchen waste. The hermetia illucens bred by utilizing the biomass organic waste can be used for treating a large amount of kitchen waste, so that the high-efficiency harmless treatment of the kitchen waste is realized, the environment pollution caused by the mass propagation of pathogenic microorganisms caused by improper kitchen waste treatment is avoided, and considerable hermetia illucens larvae can be harvested. The black soldier fly larvae contain rich protein and fat, are important high-nutritional-value feeds and can be widely used for breeding high-quality livestock products such as local chickens and the like.
In recent years, the fourth staple food strategy of potatoes is implemented by the nation, and the potatoes are one of ten special and dominant industries of agriculture and animal husbandry which are intensively developed in Qinghai province and are also one of the major industries of Qinghai province. The Qinghai province is in the Qinghai-Tibet plateau, the climate is cold, the soil is rich in potassium, and the potato ecological niche is the best ecological suitable area for potatoes in China. As potatoes are processed into starch or starch products, a by-product is produced which comprises mainly water, cell debris and residual starch granules. The fresh potato residue has a water content as high as 90%, and is not suitable for storage and transportation. However, it cannot be directly used as a feed animal because of its low protein content, high crude fiber content, and poor palatability. Due to the large yield and the centralized production season, a large amount of potato residues are accumulated, and if the potato residues are not treated in time, the potato residues occupy the field and are easy to decay to generate stink, thereby causing environmental pollution.
At present, the treatment method for potato pulp mainly comprises the following steps: (1) adding protein and other nutrient components into potato residue as animal feed; (2) preparing pectin or a pectin-starch mixture; (3) is converted intoSugar and extraction syrup are used for treating color enhancement of potato chips and chips; (4) preparing a culture medium (alcohol) in hydrolysis and fermentation; (5) extracting nutrient components from the mobile phase to obtain fertilizer; (6) diluting with water as a stabilizer or lubricant in deep well drilling; (7) production of microorganism B as Yeast Medium12(ii) a (8) Producing biogas as a microbial growth medium; (9) fermenting potato residue aspergillus niger to produce citric acid; (10) fermenting white rot fungus C12 and white rot fungus D31 to produce dietary fiber; (11) producing xylanase by solid state fermentation of aspergillus niger; (12) the microorganisms ferment single cell proteins, lactic acid or degradable materials. The above methods all need to dehydrate the potato dregs, and because the potato dregs have small particle size and good fluidity, the bound water in the potato dregs is difficult to remove, and the recycling cost of the potato dregs is high. And the resource cost is high when the fermented feed is used as animal feed of cattle, sheep and the like; the fermentation technology has high requirement on temperature, and the fermentation speed is slow when the temperature is low, so that fresh potato residues cannot be timely and effectively recycled when a large amount of potato residues are produced.
In summary, the application provides a method for breeding hermetia illucens by efficiently utilizing the organic waste of the potato residues, aiming at solving the problems of resource utilization of the potato residues and breeding of the hermetia illucens in alpine regions.
