CATDOLL : CATDOLL: Is breeding maggots profitable? Zhihu (Is breeding maggots profitable? Zhihu article)

1. Can you make money by raising maggots?

As far as I know, many people have made money from this project. But not everyone can make money. It involves many aspects such as technology, fly breeding quality, finished product processing, and finished product sales. Therefore, you must be very careful before investing. Haha, personal advice. For reference.

2. Is it true that we can learn about fly maggot farming?

Actually, I want to say that fly maggots can be cultured, but the economic benefits are poor. Generally, they can only be used as bait for domestic animals. Moreover, they look a bit disgusting, and the culture medium is also annoying. For the breeding technology, it is not very difficult. Just pay a little attention to the humidity and temperature of the culture medium. I hope this can help you.

3. Is it really profitable to raise fly maggots?

I have also seen the person you mentioned. He was once broadcast on CCTV. I personally think it is true. But to be honest, the development of this industry has reached a bottleneck period. Some superficial resources have long been exhausted, such as using fly maggots as feed. As long as you have some knowledge, you can learn it. The market space is not large. Some deep technologies are still being developed, such as the extraction of chitin from fly egg shells, etc., but the research and development of these extraction technologies requires a lot of investment, so it is reasonable for experts to say that it is not suitable to raise maggots now.

As for Professor Hu Jinlin's "Flies, Breeding and Utilization" that you mentioned, it is indeed not available on the Internet, but what is certain is that fly breeding does exist.

4. Is it profitable to raise flies?

The benefits are considerable!!

Since ancient times, fly maggot protein food has always been a hot topic of discussion. As early as the Ming and Qing Dynasties, the famous Zhong Jiefu Pharmacy in Xitang Town, Jiashan County, Zhejiang Province, used fly maggots to make the famous Eight Immortals Cake, which has been passed down to this day (now called Eight Treasures Cake). It has become a local food therapy product suitable for both the young and the old, with a unique flavor and both medicinal and edible. It is used to entertain guests and give gifts to relatives and friends during festivals. After years of careful research, American scientist Lind first proposed in 1919 that flies can be used to turn decay into magic and convert human and animal feces into animal protein. In the 1960s, the Soviet Union and North Korea and other countries successively established fly maggot factories specializing in the production of animal protein nutritional powder. In Paris, the capital of France, there is a famous insect restaurant that specializes in serving fried flies and other famous dishes. North American Indians have long cooked flies into the unique "Guchabi" cake, which is mouth-watering. In Mexico, the "hometown of insect food", fly eggs are processed into delicious and fragrant "caviar". According to a report by Swedish media in 1982, a popular dish called Housefly Lobster was first introduced in a hotel called Fokfu in the capital Stockholm. It is made by mixing 5%t fly maggot powder into flour, adding lobster and other ingredients, and deep-frying it in a frying pan to make a high-end delicacy with color, aroma and taste. It is delicious and refreshing, and has become a long-lasting signature dish of this hotel. The world-renowned American Coca-Cola Company heard the news and used 3% fly maggot protein powder. After baking and other processes, it was cooked into a unique infant biscuit, which was praised by the media as "the best food for babies". It is said that this fly maggot powder biscuit has the effect of enhancing the body's immune function and preventing colds. It is also suitable for the elderly with declining digestive function. In recent years, a new health food "Old People's Crisp" developed by a Japanese food company is also cooked with nutritious and well-known fly maggot protein powder as the main ingredient. In London, the capital of the United Kingdom, some famous restaurants have launched an innovative dish - lion snake salad, which is made by mixing fly maggot protein powder with high-grade flour, mixing it into salad, and frying it in warm oil. As soon as it was launched on the market, it was highly praised by gourmets. Other hotels are not far behind. After cooking the sterile fly maggot protein powder, they use the soy product "Qian Zhang" as a coating, add Western seasonings such as beef curry, and wrap it into a Chinese-style "baiye bun". It has become a delicious snack that people are eager to taste. In the past decade, the technology of extracting fly maggot protein has been improved day by day, and the benefits are remarkable. This new type of protein can be widely used to make pastries, nutritional supplements and additives for fortified foods, becoming an important raw material for the food industry. Germany's insect protein purification project has been put into large-scale production. The nutrients such as protein, amino acids, and fat extracted from fly maggots are used to make new health foods, which have been recognized and approved by food hygiene departments in many countries.

Not long ago, more than 80 entomologists in my country gathered at the National Resource Insect Industrialization Development Seminar to discuss the prospects of insect industrialization, including flies. During the meeting, my country's first large-scale "insect banquet" with a unique style was set up. More than ten kinds of insects that were once daunting, such as locusts, ants, and red bollworms, have been transformed into a dazzling array of delicious dishes after careful planning by scientific researchers and processing by chefs. Among them, the exquisite dishes and drinks cooked and brewed with fly maggots as the main ingredients, such as Yusun Ma Fruit, Engineering Bread, Narcissus Active Nutrition Wine, and Narcissus Active Nutrition Drink, have opened the eyes of viewers and tasters and have been praised.

There are so many of them. Authoritative sources predict that as the leader of insect food, especially fly maggots, will rise rapidly and become one of the important resources of human protein food in the 21st century, with huge development potential and promising market prospects. No wonder the Insect Protein Research Institute of Shandong University has invested 7 million yuan to build a large fly maggot factory with a monthly output of 2 tons of dried fly maggots, specializing in the production of nutritional protein powder, deacetylated chitin and maggot oil and other rare products in the market.

According to British and American medical literature, fly maggot therapy can be used to treat seriously infected wounds. The main arguments are: First, fly maggot therapy can avoid the disadvantages of antibiotic treatment that produces antibiotic properties. This treatment has no adverse reactions, does not require anesthesia, and does not harm healthy tissues at the wound. It is recommended to use fly maggots to treat necrotic wounds at an early stage. Second, fly maggots can treat infections caused by antibiotic-resistant strains. Fly maggots can eliminate bacteria in the wound, which is believed to be related to the fact that fly maggots can produce antibiotic substances and change the pH value of the wound when engulfing bacteria. Third, clinical practice has shown that fly maggots have a good effect on bedsores, diabetes, foot ulcers and postoperative wound infections. Fourth, place sterile fly maggots on the wound and cover it with a dressing to prevent escape. The fly maggots will engulf the necrotic and infected tissues at the wound. Remove the dressing after 1-3 days. At this time, the fly maggots have matured and will not continue to harm healthy tissues.

It can be said that flies are the real antibacterial champions in the insect world. They live in rotten and filthy places for their entire lives, pushing billions of bacteria and viruses but never get sick. One of the secrets is that they contain unique "antibacterial active proteins" in their bodies. Only one ten-thousandth of the concentration of this protein is enough to kill all the bacteria in the human body. Its bactericidal factor is thousands of times higher than that of penicillin! This active protein can also stimulate the secretion of human growth factor, which is conducive to wound healing. This provides new clues for humans to develop new and efficient antibiotics. Scientists imagine that if the precious antibacterial active proteins can be extracted from flies and transferred to humans, an indestructible and powerful defense line that can resist any disease can be built in the human body. In addition, the hemolymph of flies contains anti-cancer ingredients such as lectins, and the maggots contain "fecal alkali-producing bacteria", which can inhibit various bacteria of skin abscesses and promote the formation of new epidermis and wound healing. According to measurements, flies also contain 2-%-4% phospholipids, which have the functions of protecting cell membranes, lowering blood lipids, and preventing cardiovascular diseases.

In 1997, the Shanghai Science and Technology News reported that a group of experts from Wuhan University and Huazhong Agricultural University, in cooperation with American scholars, extracted chitosan, Linuo Vitality, which is highly promising and known as the "sixth essential life element for the human body", from the maggots of "engineered flies" that are "immune to all kinds of poisons and diseases". They also extracted a new type of nutritious tonic product, Linuo Jianzhisu, from the lymphatic blood of fly maggots. It has now entered commercial production.

According to a report by Jinwanbao on November 22, 2000, after two years of intensive exploration, researchers from the School of Life Sciences of Nankai University and the School of Materials Science of Tianjin University successfully isolated a series of antimicrobial peptides from the maggot plasma proteins in flies, which are efficient enough to kill a variety of pathogens. The researchers placed the antimicrobial peptides in a bacterial culture dish, and after 5-6 hours, a clear antibacterial circle was formed, and all the bacteria in the circle died. Experts confirmed that antimicrobial peptides have a power in killing bacteria that is unmatched by current medical antibiotics. Experts predict that by the 21st century, flies are expected to become the "nemesis" of a variety of pathogens.

In summary, flies and their larvae have a wide range of uses in medical care, have great potential, and have broad development prospects.

5. What are the costs and profits of maggot farming?

The cost of producing one pound of fly maggots is more than 2 yuan. If the scale is several hundred pounds, it is difficult to achieve and the cost will increase rapidly, at least 4 yuan per pound. There are about 700 fly maggots in one pound. Fly maggots are not only rich in protein and have a full range of essential amino acids, but also contain lysozyme, lectin, antibacterial skin, antibacterial protein, ergotins and other active substances. Therefore, it is an excellent feed with a new type of protein source.

6. Can you make money by raising maggots?

There is a market, but you can only make money if you can sell live maggots. If you process them into dry powder and compete with fish meal, the advantage is not obvious. There are two sets of breeding technology, one is to use feces to breed and the other is to use feed raw materials to breed. The cost is different, and the cleanliness of the maggots and social opinions are also different.

7. What is the prospect of maggot farming?

I hope my answer can help you

At present, fly maggot farming in China is mainly used as bait for other farming, and there is no real fly maggot market in China. This is mainly caused by the following reasons:

First, the deep processing technology of fly maggots is still not perfect

Fly maggots are indeed useful from head to toe. For example, the antimicrobial peptides in fly maggots are very good bactericidal protein substructures. Because they do not cause any toxic side effects to the human body, and at the same time have a highly effective sterilization ability, only a concentration of one ten-thousandth is needed to kill all germs, and they will not produce drug resistance. There are also thrombins in fly maggots that can stop bleeding in the shortest possible time. The chitin on the surface of fly maggots is an important raw material in the medical and health industry. In addition, the protein content of fly maggots is as high as about 60%, which is sometimes a very good animal protein bait.

However, we do not have the supporting technical facilities in our country to completely separate and purify them from the fly maggots. The raw materials for these products (or the production of these products) used in our country are mainly imported from European countries.

Second, the market space is small

Since there are no large-scale fly maggot deep processing enterprises in China, there are naturally fewer channels for fly maggot sales. The only sales channels for fly maggots are breeding farms for use as bait and sterile maggots for sale as food. It is difficult for large-scale fly maggot breeding farms to meet such market space.

Third, consumption concepts are changing slowly

At present, the consumption concept of consumers is still relatively conservative, and the consumer market of sterile maggots is mainly concentrated in the coastal areas, and there are few large sterile maggot markets in inland areas, because it is difficult for consumers to accept this form of goods.

Combining the above points, I personally think that it is best not to blindly make large-scale investments in camp production before finding a suitable sales channel.
