The feces that are swallowed every day change rapidly. For high-grade raw materials, feeds, fertilizers, etc. are all digitalized and programmed. After using this device, the animals and plants in the area of 1,000 acres of fertile fields directly inherit the gene of maggot protein to resist common pathogens, and the animals and plants use maggot protein biomaterials for high quality and high yield. , chemical fertilizers and antibiotics are too late to be eliminated, not only soil animals and plants have enhanced immunity, animal and plant organic agricultural products in the jurisdiction are low-cost, high-quality, and the market supply is tight. The villagers also shared the big health and precision technology to enhance immune function. Get rich dividends.

To sum up, the biological maggot protein industry chain provided by the present invention completely solves the negative impact of fly maggots, and the fully automated equipment fully exerts the two huge functions of flies, high-quality protein and high-strength immunity. The function of biological fermentation to kill harmful bacteria is also reflected in the nuclear fission benefits of tens of thousands of times the protein produced by fly maggots. This project can lay a solid foundation for the development of the integrated agricultural and industrial health industry such as feed, fertilizer, medicine, and food in the region. .

Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
