Fly maggots have high nutritional value as feed.

The larvae of Musca domestica are called maggots, which are high-quality animal protein feed. When the laying hens were fed with 10% fly maggot powder, the laying rate was 20% higher than that of the layers fed with the same amount of fish meal, and the feed reward was increased by more than 15%. So, how to raise maggots?

Procedure:

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 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 dung, 20 kg of health care liquid, 5 kg of corn meal, evenly mixed with dung in the fermentation tank, sealed with plastic film, and can be used after 1-3 days of fermentation.

two。 Send the fermented manure to the maggot room and stack 3 strips in each pool, each 0.8 meters long, 0.2 meters wide and 0.15 meters high. The time of entering feces is 8: 9 o'clock every day in winter and spring and 16: 18 o'clock in summer and autumn.

3. Put egg collections on the dunghill, each in 3 small piles. The formula of egg collection is as follows: 100 kg of dung, 1 kg of wheat bran, 100 g of fish meal, 150 g of peanut bran and 1.5 kg of water. Mix well and put it on the dunghill. After putting on the egg collection, it is forbidden to walk in the maggot room.

4. Under normal circumstances, after the egg collector is placed, the flies will gather on the egg collector to lay eggs and cover the exposed egg mass with a small number of egg collectors at 20:00.

5. At room temperature 25-35 ℃, the eggs usually hatch into maggots after 8 hours. If the dung pile is found to be too dry, sprinkle a small amount of water. The maggots first eat the egg collection and then get into the dunghill to grow; 24 hours after hatching, the previously neatly stacked dung pile has been eaten and crawled apart by maggots. At this time, we should pay attention to keep the moisture of the dung pile, and when it is found that the dung pile is dry, we should add water in time. At this time, the best way to add water is to use the pigsty water treated with health care liquid, and the best range of added water is that there is no water flowing out of the dung pile. As the maggots continue to grow, the dung pile has completely dispersed. 72 hours after the maggots hatch, some first-mature maggots begin to climb out of the dung pile and fall into the maggot bucket. 72-96 hours is the peak period for crawling out. At this time, the dung pile scattered by maggots should be stacked into a large pile twice a day, in order to keep the loose feces from blocking the edge of the pool to prevent the maggots from climbing smoothly into the maggot bucket. Generally, on the fourth day after putting it into the dung, the maggots in the dung pile have basically climbed out, shoveled out the residual dung, re-put it into the newly fermented dung and recycled production. At 10 o'clock every morning, it is required to spray all parts of the maggot room with a 50-fold diluted health care solution to eliminate the stench and sterilize.

6. The maggots are collected twice a day, at 8 o'clock and 17:00, respectively. Wear a leather glove when collecting maggots, and then grab it. Fly maggots can be fed directly to animals without disinfection.

7. Every 40 square meters of maggot room to ensure that there are more than 300000 species of flies, red-headed flies account for 80%, small houseflies account for 20%. When collecting maggots every 3 days, leave 1 kilogram of maggots and put them in a special hatching pool or basin to hatch into pupae to ensure the number of flies.
