What are the common methods of fly maggot farming technology?
Fly maggots are the larvae of flies, and the places where they often appear tend to make people feel rather disgusted. But they are a very good feed. So, what are the fly maggot farming techniques?
1. Preparation of the fly maggot farming house
1. The breeder fly room is specially used to raise adult flies. Generally 20-40 sq m is enough. An old house can be renovated for this purpose, which can also/2 save costs. The room must be fitted with a screen door and screen windows to prevent them from escaping.
2. The maggot-rearing shed is specially used to cultivate fly maggots for protein feed. A simple shed can be built, as long as it can block wind and rain.
3. The area around the house must be enclosed with 1 m high screen netting to prevent chickens, ducks and other animals from entering. The rearing ponds should be simple cement ponds, each with an area of 1.5 sq m to 2 sq m and a side height of 20 cm.
2. Fermentation of manure material
Under normal circumstances, 1 kg of Rujin manure fermentation agent can ferment 1.5 tons of manure (about 3 tons of fresh manure). The fermentation agent must be mixed and diluted with rice bran (or cornmeal, wheat bran) at a ratio of 1:5, then evenly sprinkled into the manure material pile and mixed thoroughly. Adjust the moisture of the fermentation material to between 60-65%.
How to judge: tightly grab a handful of the material; water marks should show between the fingers but no water should drip, and it should scatter when it falls to the ground. Pile up the manure material mixed with the Rujin manure fermentation agent. The pile should not be too small (a height of 1.2-1.5 m is suitable, a width of 2 m, and a length of 2-4 m). During fermentation, turn it 2-3 times, keep the temperature at around 65°C, and fermentation can generally be completed within one week.
3. Hatching and rearing of fly maggots
1. Hatching of pupae. Place the eclosion tray into the fly cage and tie the working opening tightly. As long as suitable temperature and humidity are maintained, the fly pupae can emerge as flies after 3-4 days.
2. Temperature and humidity requirements. Generally, the most suitable temperature for fly pupae is 25°C-30°C, and the relative air humidity should preferably be 50%-80%. If the temperature is low in winter, turn on a heater to raise the temperature. If conditions permit, an air conditioner can also be installed; at around 36°C, they can emerge as flies in two days.
Finally, in fly maggot farming, attention must be paid to temperature and humidity, and adjustments must be made according to actual conditions. Only in this way can the quality of the fly maggots be ensured.
