CATDOLL : CATDOLL: How many fly maggots can be raised in one ton of pig manure?

1. How many fly maggots can be raised in one ton of pig manure?

Breeding maggots with every ton of pig manure can produce 200-300 kilograms of maggots. Breeding earthworms with pig manure can produce 40-100 kilograms of earthworms.

Pig manure is used to breed fly maggots. Each ton of pig manure can produce 200-300 kilograms of fly maggots.

2. Maggot breeding technology

Maggot breeding technology:

Farming equipment

1. Fly cage. The cage is 1.5m high (50cm for the cage foot), 60cm wide and 100cm long. The bottom of the cage can be made of plywood, and the four sides are nailed with 12-mesh lead sand windows. A 10×10cm hole is opened on one side of the rectangle, and a trouser leg is sewn on it as an inlet and outlet for changing materials.

2. Maggot breeding platform. Build a platform with a slope of 10 cm. Smooth the inside of the platform with cement. Mature maggots tend to crawl to the higher side.

3. Production process:

①Formula of manure:

Raw materials for maggot breeding: 80% fresh pig manure, 10% wheat bran, 10% peanut residue

(Note: Spray with EM 1:10 water every day to deodorize)

Egg collection material: 80% fresh pig manure 10% wheat bran

9.5% peanut hawthorn 0.5% ammonium bicarbonate

Fly breeding drink: 5% brown sugar 5% milk powder 5% fresh eggs

0.2% Vitamin C 0.2% Methionine 84.6% Water ② Fermentation of manure:

Use EM in a dilute fermentation ratio of 1:10. The humidity is between 70-80%. Mix and ferment for 1-2 days before use. It can eliminate toxic and harmful gases in the manure during the maggot breeding process.

③Put the egg-collecting material on the manure of the maggot breeding platform. Young maggots can be seen the next day. After 2 days, mature maggots can be seen crawling out of the manure pile and crawling to the slightly higher side of the platform. Take it out and rinse it with 1/5000 potassium permanganate solution for 10 minutes before use.

④ Timing of feeding, collecting fly eggs and taking maggots

Feeding (fly breeding drink): at irregular intervals, feed after the flies have finished eating. Be careful not to feed too much each time to prevent the flies from dying.

Egg collection materials: put them into the cage in the morning and take them out and put them into the maggot breeding platform in the evening.

Taking maggots: depends on production and application.

According to this method, each cage can produce 20 kilograms of maggots per day. Each batch of manure raw materials can produce a batch of maggots, which are then used to breed earthworms. Within the suitable temperature range for maggot growth, high or low temperatures will affect the length of time for maggots to emerge. Therefore, the production plan should be adjusted at any time according to temperature changes to ensure a stable and balanced supply of fresh maggots.

Breeding formula

1. Feed formula Feed is the material basis for raising fly maggots. Through the comparative breeding test of fly maggot feed, it is better to breed fly maggots with pure chicken manure and pig and chicken manure in a certain proportion, while cattle manure is worse for breeding maggots (Table 1)

Table 1 Comparison of maggot breeding feed formula experiments

Feeding name Combination project Pure pig manure Pure chicken manure Pure cow manure Pig and chicken manure 1:2 Pig and chicken manure 1:1 Pig and chicken manure 2:1 Pig and cow manure 1:1

Note: The number of eggs collected is 5,000

According to the results in the table, a set of formulas are obtained for selection:

1. Mix 1 part of pig manure and 1 part of chicken manure with water, and the water content should be about 80%.

2. Mix 1 part pig manure and 2 parts chicken manure with water, the water content is 80%

3. Mix 2 parts of pig manure and 1 part of chicken manure with water to a water content of 80%.

2. Use pig manure as bait to reduce the cost of raising maggots. According to many data, wheat bran is the main bait for producing fly maggots. In order to reduce the cost of raising fly maggots and improve economic benefits, we conducted an experiment of artificially raising fly maggots using pig manure instead of wheat bran as bait. After the experiment, it was found that 2 kg of wheat bran was needed to produce 500 grams of fresh maggots using wheat bran as bait, and the cost of 1 kg of fly maggots was 0.25 yuan (excluding equipment investment). Although the protein content of wheat bran after raising maggots did not decrease after testing, it was not effective for feeding livestock and poultry, which resulted in a large amount of wheat bran wasted, limiting its promotion and application. The method of raising fly maggots with pig manure as bait is the same as that of raising fly maggots with wheat bran, and the yield of fly maggots per square meter is basically the same. The main nutrients contained in the fly maggots produced by the two baits are also basically the same through testing, and no abnormalities occurred during the breeding process. The cost of producing fly maggots with pig manure bait has been reduced from 0.5 yuan to 0.14 yuan per kilogram (pig manure is not priced, only the cost of artificial feeding and fly breeding, etc.) Practice has proved that using pig manure as feed to raise fly maggots has a wide source of feed, low production cost, and simple breeding methods. The manure residue after maggot breeding can also be used as fertilizer or biogas raw material, which not only makes full use of bioenergy, but also creates favorable conditions for vigorously promoting fly maggot production.

Animal carcasses can also be used, but they must be processed with probiotic concentrate.

3. How many maggots can be produced in one kilogram of pig manure?

First of all, it depends on whether your culture medium is rich in nitrogen and other nutrients. When pig manure is rich in nitrogen, flies will smell the fermentation and then lay eggs. The number of eggs laid determines your production base.

The second is the incubation temperature. If the temperature is too high or too low, the hatching volume of the eggs will be greatly affected.

During the cultivation process, we must pay attention to controlling various factors, ventilate in time, and keep the moisture of the culture medium at around 65%. It should not be too wet or too dry, so as not to affect the growth of maggots.

During the growth process, it is very important to harvest the big ones and sell them in time, otherwise they will hatch into young flies, which will reduce the yield.

Generally speaking, at a temperature of 35 degrees Celsius, pH 6.8, and an air relative humidity of 85%, the production can be completed in 7 to 15 days. One kilogram of fermented pig manure can successfully hatch about 60 grams of fly maggots. If it is a fresh product, it can reach more than one kilogram.

Then replace the culture medium with new one and start a new round of production.

Fly maggots are high in protein and can be used as an excellent live feed for other aquaculture. They have a short production cycle and considerable profits. The waste produced is still an excellent organic fertilizer, which can be provided to fruit trees, flowers and other planting industries. It can also be used as an excellent substrate for earthworm breeding units.

Generally, 4 kg of pig manure can produce 1 kg of fly maggots, but it can be more or less depending on factors such as temperature.

It depends on your fermentation recipe. Also, the number and variety of your maggots vary greatly.
