Detailed Guide to Maggot Farming Technology: Methods and Techniques

For maggot farming, you can use a maggot rearing pool built with bricks with a side height of 20 cm and an area of 1-3 sq m, or build a rack with bamboo or wood and use plastic trays to rear maggots. A plastic tray with a diameter of 50 cm can rear 1.5 kg of maggots using only 3 kg of wheat bran, and they can be collected for use after 3-4 days of rearing. The sources of maggot feed are relatively wide, and the cost of different maggot feeds varies, so you can choose reasonably. Wheat bran has relatively high nutritional content and is also slightly more expensive, so it is generally used to breed maggots, while low-priced distillers' grains, soybean residue, etc. can be used as feed for commercial maggots. If wheat bran is used as maggot feed, generally 1 kg of wheat bran can produce 0.4-0.5 kg of maggots (depending on the quality of the wheat bran). When using it, add water and mix evenly; the suitable dryness and moisture level is that water comes out when squeezed by hand and the mixture breaks apart when touched. If semi-dry and wet materials such as distillers' grains or soybean residue are used, they can be cultured without adding water.

Maggot Farming Technology

Pour the wheat bran on which the flies have laid egg clusters into the tray, add maggot feed such as distillers' grains, soybean residue, or wheat bran, and mix slightly. Note that the fly eggs should not be exposed on the surface of the maggot feed, so as to avoid loss of water and loss of vitality. The thickness of the maggot feed should be based on the standard that the fermentation temperature within the maggot feed is not higher than 40°C and not lower than 20°C, generally 5-10 cm. In summer, when the temperature is relatively high, the maggot feed should be appropriately thinner; conversely, in winter, when the temperature is relatively low, the maggot feed can be appropriately thicker. If human or livestock manure is used, it must be used after killing bacteria and parasites. For the ratio of material to maggots, taking chicken manure as an example, generally 3-4 kg produces 1 kg of fresh maggots. Regardless of which raw material is used for rearing maggots, the dryness and moisture level of the maggot feed should be controlled at 60%-65%.
