Feeding method for increasing yield of hermetia illucens by using kitchen waste and chicken manure

Abstract

The invention discloses a method for increasing yield of hermetia illucens by using kitchen waste and chicken manure. The method comprises the following steps: (1) collecting fresh kitchen waste, andpicking up inorganic impurities in the kitchen waste, then, filtering out extra water by a filter net, and preparing kitchen waste pulp with moisture content of 70%-85% by a pulping machine; (2) collecting fresh kitchen manure, uniformly mixing the kitchen waste pulp and the collected fresh chicken manure in a certain proportion to obtain a mixture, so that the dry weight content of carbohydrate in the mixture is 28%-40%, the dry weight content of protein is 15%-25% and the moisture content is 65%-80%; (3) laying the mixture in a hermetia illucens culture tank, then, putting hermetia illucenslarvae at 2-3 day age into the hermetia illucens culture tank, controlling the temperature at 29-37 DEG C, and carrying out treatment for 7-13 days; and (4) before the hermetia illucens larvae enter aprepupa stage, separating the hermetia illucens from hermetia illucens dung. The method can greatly reduce the feed ratio of the mixture obtained by mixing the kitchen waste pulp and the fresh chicken manure, and greatly increase the larva producing rate of the hermetia illucens.

Description

technical field [0001] The invention belongs to the technical field of combined treatment of chicken manure and kitchen waste, and in particular relates to a breeding method for increasing the yield of black soldier flies by using kitchen waste and chicken manure. Background technique [0002] Kitchen waste is a general term for leftover waste from meals and kitchen waste. The composition of food waste is mainly composed of protein, starch, animal and vegetable fat, sugar, and salt. Its complex composition is a mixture of various substances such as oil, fruit peel, vegetables, rice noodles, fish, meat, and water. It is rich in nutrients and has Resource utilization value. Traditional landfill and incineration treatment will cause secondary pollution and pose hidden dangers to environmental safety. [0003] Large-scale chicken farms produce a large amount of chicken manure, and improper treatment may easily cause environmental pollution around. At present, the treatment of ...

Traditional landfill and incineration treatment will cause secondary pollution and cause hidden dangers to environmental safety

[0003] Large-scale chicken farms produce a large amount of chicken manure, and improper treatment may easily cause environmental pollution around. At present, the treatment of chicken manure includes: 1. Preparation of organic fertilizer, 2. Direct return to the field after anaerobic fermentation, 3. Use of scavenging insects Among them, the use of black soldier flies has low energy consumption and can also obtain insect protein, which has attracted much attention. However, feeding black soldier flies with feces alone has a low insect production rate and a large amount of ammonia gas is produced during the breeding process.

[0004] The growth status of black soldier flies is affected by the nutrient composition of the feed, and is directly related to the energy level. When the energy in the feed is too low, the growth rate of the black soldier flies will be reduced due to insufficient energy intake, and the protein utilization rate in the feed will also decrease. thereby increasing the material-to-weight ratio

[0005] Chinese patent CN105906390A discloses a method for treating food waste. In this patent, paddy field straw is added to the food waste to adjust the carbon content, and livestock and poultry manure is added to the food waste to adjust the nitrogen content. The carbon-nitrogen ratio of the mixture, but because the carbon element in rice field straw mainly exists in cellulose molecules, and cellulose cannot be absorbed and decomposed by black soldier flies, the effective carbon-nitrogen ratio of the obtained mixture will decrease, and then will slow down the growth rate of black soldier flies and will reduce the utilization of the resulting mixture

[0006] Chinese patent CN108739672A discloses a system and method for resource utilization of livestock and poultry manure and kitchen waste to incubate black soldier flies. This patent mainly discloses a system for resource utilization of livestock and poultry manure and food waste to incubate black soldier flies, but there is no specific regulation The mixing ratio of livestock and poultry manure and kitchen waste does not specifically limit the dry weight content of protein, dry weight content of carbohydrates and water content in the mixture obtained after mixing livestock and poultry manure with kitchen waste. In fact, black The growth status of soldier flies is greatly affected by the nutrient composition of feed, and the growth status of black soldier flies is directly related to the energy level of feed. When the feed energy is too low, the growth rate of black soldier flies will be reduced due to insufficient energy intake. The utilization rate of protein in the medium will also decrease, thereby increasing the feed-to-weight ratio, so the patent does not adjust the appropriate proportion of protein and carbohydrates in the mixture obtained by mixing livestock and poultry manure with kitchen waste, which in turn will affect the black soldier fly. growth rate, and will affect the utilization rate of the obtained mixture, and in this patent, it is also necessary to add a certain amount of biological enzymes to the mixture obtained after mixing livestock and poultry manure with kitchen waste, and use biological enzymes to decompose the obtained Mixture, so the process is more complicated
