CATDOLL : CATDOLL: What are the nutritional values ​​of fly maggots?

1. What are the nutritional values ​​of maggots?

More than 95% of the tissue of fly maggots can be used as feed or food, and there is very little waste. Fly maggots have a high protein content and contain a full range of essential amino acids. They can be used as high-protein food and are ideal protein food for human consumption. Fly maggots have high riboflavin and vitamin E content. Vitamin E has an antioxidant effect that protects lipids in cell membranes from damage by peroxides and is an indispensable nutrient and medicine. Fly maggot fat is rich in unsaturated fatty acids and can be purified as medical and cosmetic fat. Fly maggot fat can improve the skin's anti-wrinkle function and has a certain effect on treating and relieving symptoms of skin diseases. The epidermis of fly maggots also contains chitin and chitosan, which have the effect of lowering blood pressure. It can also be used to make artificial skin that only activates cells, has antibacterial and hemostatic effects, and can be used as a food stabilizer, emulsifier, preservative and clarifier.

2. How to separate maggots?

(1) Separation of large and small pots: Place a smaller plastic pot inside a larger pot, wet the four walls of the small pot with a damp cloth, pour maggots and materials into the small pot to a thickness of about 2 cm, and the maggots will crawl along the pot wall into the large pot.

(2) Photo separation method: Place a sieve with holes large enough for maggots to drill through on a plastic basin. Mix the maggot feed with water and pour it into the sieve. The thickness should not exceed 2 cm. Place it in the sun. Since rope maggots are afraid of light, they will try their best to drill down and fall into the basin below.

(3) Automatic separation: If you have a maggot breeding room, you can place some containers such as maggot bowls around the maggot breeding pool to allow the maggots to separate automatically by taking advantage of their habit of automatically crawling out before hatching.

3. Where can I buy fly maggots?

It is sold in the suburbs of Liuzhou City, Liujiang District, and Shatang Town.

Production capacity: 500 catties of fresh live maggots are produced every day (production is available all year round). Unordered maggot quota: 100 catties/day. (Updated as changes occur) For those in the suburbs of Liuzhou, Liujiang area, and Shatang Town, free door-to-door delivery is available for purchases of more than 20 catties at a time.

4. What are the methods of cultivating maggots?

There are three methods for cultivating fly maggots: one is the soil pile method, the other is the fly cage method, and the third is the jar basin method. The soil pile method uses fermented chicken manure, pig manure or food factory scraps (such as wine lees, soy sauce lees, vinegar lees), slaughterhouse scraps, etc., spread on the ground to attract flies in nature to lay eggs on them. Generally, about 150 grams of fly maggots can be harvested per kilogram of feed within 7 days.

The key to this method is to harvest the maggots in time and feed them to frogs in time. Otherwise, a large number of artificially produced flies will fly out of the frog farm and cause great harm to people. You can also put the material for cultivating maggots into a sieve, put the sieve on the container, or hang it 30 cm above the water surface of the frog pond. The maggots can use their light-avoiding and drilling properties to drill out of the sieve and fall into the container or the bait table to become live bait for frogs.

The fly cage method of raising maggots is to make several fly cages with a length of 60 cm, a width and a height of 40 cm each, and sealed with nylon window screens on all sides. A round hole with a diameter of 20 cm is opened on one side of the cage. A cloth tube with two empty ends is sewn on the edge of the hole for adding culture medium. Each cage can raise about 10,000 breeding flies. The bait for breeding flies is milk powder and brown sugar. For every 10,000 breeding flies, 5 grams of milk powder and 5 grams of brown sugar are used daily, boiled with an appropriate amount of water, and put into a small basin after cooling, with a few short straws in it for the breeding flies to absorb.

Use another deep small basin or bowl, filled with wheat bran or rice bran with a water content of 70%, and place it in the cage for the breeding flies to lay eggs. Under the condition of 24 to 33 degrees, each female breeding fly lays about 100 eggs each time, and the eggs are in blocks. Take out the bran and bran materials with eggs from the fly cage every day, and place them on the maggot breeding material (the ratio of chicken manure to pig manure is 1:2) for incubation. The material is about 7 cm thick, the humidity is about 70%, and the temperature is 18 to 33 degrees. After 3 to 22 hours, the larvae can be laid.

After 4 to 5 days, the larvae will eat manure and grow until they pupate, and then they can be harvested. Every 500 grams of manure can produce about 10,000 maggots, with an average weight of 20 to 25 mg per maggot, and a total weight of 200 to 250 grams, that is, the feed-maggot ratio is about 2:1. The breeding flies lay eggs 5 to 6 times in their lifetime, and begin to age after 7 to 10 days. At this time, the fly cage can be treated with hot water to kill the aged breeding flies, and then new breeding flies can be loaded.

The method of raising maggots in a jar or basin is to place animal carcasses or internal organs in a container such as a jar or basin to attract flies to lay eggs. At 30:1, a large number of maggots will grow in about 4 days and can be dug out and fed to frogs.

5. How to raise maggots?

The larvae of flies are called maggots. Maggots are rich in protein and essential amino acids, vitamins, inorganic salts and other nutrients for animals. They have soft skin and small size, and are a kind of fresh bait that stone frogs like to eat. Its nutritional value, digestibility and palatability are equivalent to high-quality fish meal. According to measurements, fresh maggots contain 12.9% crude protein and 2.61% crude fat. Due to the mature technology of raising maggots, simple equipment and high reproduction rate, the nutritional value is equivalent to that of earthworms.

Therefore, raising fly maggots is an important way to solve the problem of live bait for stone frogs. The morphology and habits of fly maggots Flies belong to the phylum Arthropoda, class Insecta, order Diptera, and are completely metamorphosed insects. Flies are divided into three parts: head, thorax, and abdomen. The thorax has three pairs of legs and one pair of wings. The abdomen is oval with a wide black vertical stripe in the middle. The whole body is gray-black, with four pairs of black vertical stripes on the back. The abdomen is gray-yellow, and the female has a conical ovipositor at the end of the abdomen.

The body length is 6 to 7 mm. When a fly is just hatched, it can only crawl but not fly. After one hour, it will start to fly and start to eat and drink water. After another five days, it can reproduce. The growth and reproduction speed of flies is faster than that of earthworms. A female fly can lay about 1,000 eggs in its lifetime. The life cycle (the time from the eggs hatching into maggots to the pupae emerging and the flies starting to lay eggs) is about 15 days.

However, if they are not well controlled during extensive breeding, they are likely to turn into flies. The cost of cage breeding is much higher than that of earthworms. However, since fly maggots reproduce quickly and have the same nutritional value as earthworms, they are still one of the important sources of bait for stone frogs. Flies mostly live and move indoors and are omnivorous. Their favorite foods include sweet syrup, milk, fishy fish, smelly rotten meat, feces, fruits, garbage, ammonia water, etc.

Temperature conditions are important factors affecting the life, growth and reproduction of flies.
