How to raise maggots?

What are maggots? It is the larvae of maggots. I believe everyone has seen maggots. From the appearance alone, maggots are a kind of disgusting small insects. However, maggots have high nutritional value and have a particularly high protein. The nutritional value of animals fed by maggots will be higher.

How to breed maggots?

Fermented dung material-feeding into maggot room-piling into strips-putting on egg collection material-covering egg mass after laying-keeping water and incubating maggot-automatic separation-collecting maggot-comprehensive utilization-shoveling out residual dung-repeating cyclic production.

1. Manure formula and fermentation: formula 1: fresh pig manure (within 3 days) 70%, chicken manure (within a week) 30%; formula 2: fresh pig manure from slaughterhouse 100%; formula 3: pig manure 60%, bean dregs 30%, bran 10%; formula 4: chicken manure 70%, distiller's grains 30%. Fermentation method: 1 ton of manure, 20 kg of health liquid, 5 kg of corn flour, mixed with manure in fermentation tank, covered with plastic film, sealed tightly, fermented for 1~3 days, then used (short in summer and long in winter).

2. Send the fermented manure to the maggot room and stack three in each pool, each 0.8 m long, 0.2 m wide and 0.15 m high. The time of feces intake is 8~9 o 'clock every day in winter and spring, and 16~18 o' clock in summer and autumn.

3. Put eggs on the dung pile, each with three small piles. The formula of egg collecting matter is: calculated by 100 kilograms of feces: wheat bran 1 kg, fish meal 2 liang, peanut bran 3 liang, water 1.5 kg. Mix well and put on the dung heap. After putting in the egg collection, it is forbidden to walk around in the maggot room.

4, under normal circumstances, after putting on the egg collection, flies will gather on the egg collection to lay eggs, at 20 o 'clock in the evening with a small amount of egg collection to cover the exposed egg mass, maggot breeding technology to provide.

5, at room temperature 25~35℃, egg mass generally hatched into small maggots after 8 hours, then if the dung pile is found to be too dry, sprinkle a small amount of water. The maggots eat the eggs and burrow into the dung heap to grow; 24 hours after hatching, the dung heap has been eaten and crawled. At this time, attention should be paid to maintaining the water content of the manure pile. When it is found that the manure pile is dry, it is necessary to add water in time. At this time, it is best to add water to the pigsty water treated with health care solution. The amplitude of adding water is better to see no water flowing out of the manure pile. As maggots continue to grow, the dung pile has been completely scattered. After 72 hours of maggots hatching, some mature maggots begin to climb out of the dung pile and fall into the maggot collection bucket. The peak period of climbing out is 72~96 hours. At this time, the dung pile that has been scattered by maggots should be stacked into a large pile twice a day. The purpose is to clean up and keep the loose dung from blocking the pool and preventing maggots from climbing into the maggot collection bucket smoothly. Generally, on the fourth day after putting in dung, the maggots in the dung pile have basically climbed out (a small amount of unclimbed maggots are shoveled out and stacked in the chicken's place to help the chickens clean up the maggots left), shovel out the residual dung, re-put the newly fermented dung, and recycle production. At 10 o'clock every morning, it is required to spray all parts of the maggot room once with a 50-fold dilution of the health solution to eliminate odor and sterilization.

6. The maggots in the maggot collection bucket should be collected twice a day, at 8 a.m. and 5 p.m. respectively. When collecting maggots, wear a leather glove first, and then grab it. Fly maggots can be fed directly to economic animals without disinfection.

7, a 40 square meters of three-dimensional fly breeding technology room requirements to ensure that there are more than 300,000 species flies, red-headed flies accounted for 80%, small houseflies accounted for 20%. On average, 1 kg of fly larvae are collected every three days and placed in a special incubation tank or a basin for pupae to hatch (pupae take about 72 hours, pupae hatch into flies takes about 72 hours) to ensure the number of flies. Male flies generally have a life span of only 7 days, while female flies generally have a life span of 15 to 25 days.

Daily management of breeding maggots

In the breeding process, we should pay attention to daily management work. Add fly feed, place eggs and change drinking water in time every day.

At the same time, the incubation time of eggs should be recorded in time to facilitate timely egg collection. After the staff leave, clean the floor of fly room and maggot room. Flies are fed on food trays that are cleaned every two days, including sponges. The sponge is replaced every month.

In addition, housefly is an important health pest, in all aspects of breeding management, we should do a good job of controlling breeding to prevent breeding populations from entering the natural environment.

With the development of livestock and aquaculture, the demand for protein feed is also increasing. Breeding maggot has the advantages of short cycle, high yield and low cost, so it is the first choice for producing animal protein feed. A livestock farm with a fly maggot farm, it is equivalent to building an insect protein feed production plant. Feces discharged by livestock and poultry are used to raise maggots, so as to obtain high-protein feed, turn waste into treasure and change harm into benefit. And the excrement after breeding maggots can be used as high-quality organic fertilizer for crops, used to grow food and vegetables. This special conversion function is beyond the reach of other forage insects.

What is the prospect of breeding maggots?

With the development of livestock and aquaculture, the demand for protein feed is increasing. At present, many countries regard artificial breeding insects as the main direction to solve the source of protein feed. In maggot, yellow mealworm, silkworm chrysalis and other feed insects, maggot breeding is particularly worth mentioning.

Flies reproduce fast. It is estimated that a pair of flies can breed 200 billion maggots in four months and accumulate more than 600 tons of pure protein. It takes only 1011 days for maggots to develop from eggs to adults, and only 45 days for maggots to mature maggots. The cycle is short, the reproduction is fast, and the yield is high. 0.08 mg of newly hatched larvae. After 45 days of growth at 24℃ and 30℃, the weight of maggots can reach 2050 mg, and the total biomass increases by 250350 times. Insects, as lower animals, have a production efficiency of 1540 times that of mammals, although their assimilation efficiency is about half that of mammals. It is unmatched by other methods of producing animal protein. If pigs and cattle grow at this rate after birth, their weight will reach 325KG and 7500KG respectively after 5 days. The feeding habits of maggots are miscellaneous and the raw materials for feeding livestock manure are widely available. Wheat bran, rice bran, distiller's grains, bean dregs and other agricultural and sideline products can be used for maggots breeding. What is more rare is that maggots are extremely fond of feeding livestock manure, pig manure, chicken manure, duck manure and other livestock manure. A livestock farm with a fly maggot farm, it is equivalent to building an insect protein feed production plant. The raw material is feces discharged by livestock and poultry, and the product is high-quality fly maggot protein feed. Waste into treasure, change harm into profit, breeding maggot feces, both odorless, do not attract flies, but also fertile sparse male, is a high-quality organic fertilizer for crops, this special conversion function, is beyond the reach of other feed insects.

Ecological habits of maggots

In order to successfully raise maggots, we must first understand its ecological habits before raising them. Biologically, flies belong to "complete metamorphosis insects", which experience four stages in their life: egg, larva (maggot), pupa (fly species) and adult (fly).

Among them, the egg stage is 1 day, the maggot stage is 4~6 days, the pupa stage is 3~4 days, and the flies mature sexually after 4 days of emergence and begin to mate and lay eggs. Flies can live up to a month. In actual production, each batch of flies should be eliminated in time after 20~25 days of breeding. Flies can reproduce on an annual basis at the right temperature in captivity.

Generally, most of our common flies are red-headed flies and houseflies, but in contrast, houseflies have better adaptability than red-headed flies, and their food habits are miscellaneous. Therefore, we choose to raise houseflies here. If you are a first-time breeding maggot, it is recommended that you go to a special maggot farm to buy fly seeds. After a period of time, the fly seeds can grow on their own.

Although maggots look disgusting, but for the development of agricultural industry breeding industry is really not small virtual, many chickens, ducks and other animals are mainly eating maggots grow up, its nutritional value is much higher than eating other food, buy more expensive. Even the eggs laid are rich in nutrients.
