[0002] With the rapid development of China's animal husbandry, the resource treatment and utilization of livestock and poultry waste has attracted widespread attention from the country and society. Livestock and poultry manure contains a large amount of undigested protein and crude fat, but at the same time, antibiotics, trace elements, and drugs added during the feeding of livestock and poultry will remain in the manure, which will cause air, water and soil pollution, posing a threat to the environment and human health. The treatment of livestock and poultry manure has always been a difficult point in environmental protection, especially in the context of large-scale and intensive breeding, where excess manure has become an important issue restricting the development of the breeding industry. Earthworm breeding can not only quickly and efficiently treat livestock and poultry manure, convert it into earthworm manure that is easily absorbed by plants, and realize the recycling of resources, but also slow down the spread of antibiotic resistance genes in livestock and poultry manure, and degrade some antibiotics through the action of microorganisms and enzymes in the earthworm intestine. The cultivated earthworms themselves also have extremely high utilization value. They can be processed into animal-derived protein feed, and can also be used to produce food, medicines and cosmetics. The development prospects of the large-scale earthworm breeding industry are very broad.
