CATDOLL : CATDOLL: How to raise maggots using tofu dregs?

1. How to raise maggots using tofu dregs?

Tofu dregs method for breeding maggots:

Method 1: Use 25 kg of tofu dregs and dishwashing water, put them into a tank and mix well. After 3-5 days, a large number of maggots will naturally breed in the tank. Take out the maggots and mix them into the feed to feed the eels.

Method 2:

At the same time, you can also ferment the tofu dregs, put them into an earth pit, add some rice washing water, stir them and seal the mouth. After about 5-7 days, a large number of maggots will be produced.

The method of attracting flies and breeding maggots: Flies have strong reproductive capacity in summer. You can choose a sunny place outdoors or in the courtyard, dig a small pit with a depth of 0.5 meters, a length and width of 1 meter, build it with bricks, and then smooth it with cement. Use wooden boards or prefabricated cement boards as the top cover, and install light-transmitting windows. Seal the windows with glass or transparent plastic cloth, and then open a small opening with a length of 17 cm and a width of 7 cm. Place small animal carcasses or human and animal feces in the pool to lure flies to enter and lay maggots.

It is best to use fresh feces as feed for flies, which will have a better effect.

After about 10 days, each pond can produce about 6 kilograms of maggots, which are not only large but also fat. Let's take a look at various methods of raising maggots.

The method of breeding maggots in soil piles is to mix garbage, alcohol, turf, chicken feathers, etc. into a paste, pile it into a small soil pile, and seal it with mud. After about 10 days, a large number of maggots will be produced. This method is simple and easy.

The tofu dregs method of breeding maggots: use 25 kg of tofu dregs and dishwashing water, put them into a tank and mix well. After 3-5 days, a large number of maggots will naturally reproduce in the tank. Take out the maggots and mix them into the feed to feed the eels.

At the same time, you can also ferment the tofu dregs, put them into an earth pit, add some rice washing water, stir them and seal the mouth. After about 5-7 days, a large number of maggots will be produced.

Cow dung maggot breeding method: Mix the dried and crushed cow dung with rice bran, pile it into small piles with sludge, and cover it with straw mats. After about 10 days, a large number of small maggots will also grow. Turn over the soil pile, gently separate the maggots, and then pile the raw materials. After a few days, many maggots will be produced again.

Fly maggot farming

Fly maggots are used in livestock and poultry breeding. They have good palatability, high conversion rate, and rich nutrition. The nutrition is 1.3 times higher than bean cake. According to analysis, the protein content of fresh maggots is 15.62%, and the maggot powder contains 59% to 63% crude protein and 10% to 20% crude fat, which is similar to the content of imported Peruvian fish meal. The content of each amino acid in maggot dry powder is higher than that of domestic fish meal, the total amount of essential amino acids is 2.3 times that of fish meal, and the lysine content is 2.6 times that of fish meal. In addition, it also contains 17 trace elements such as iron, zinc, and copper. Fly maggots are an ideal high-protein livestock and poultry nutritional additive.

Feed equipment and management of fly species

Maggots come from flies, and maggots must be raised before flies. Flies have a strong reproductive capacity, with a female fly laying 100 to 200 eggs each time, and a pair of flies can reproduce 10 to 20 generations a year, producing 266 billion flies in 4 months, with a cumulative pure protein of more than 600 tons, which is unmatched by other methods of producing animal protein.

1. Design of fly house. Flies should be raised indoors. It is best to build a new fly house in a semi-basement. The breeding room of the fly house does not open directly to the outside. There is a closed corridor inside the house. The corridor is entered from the back door of the studio. Black curtains should be hung on the door to prevent flies from escaping. Screens and heating equipment should be installed on the windows. The room temperature should be kept at 20-30℃, with a minimum of no less than 15℃ and a maximum of no more than 35℃.

2. Main equipment. There are fly cages, food trays, egg-laying trays, and eclosion trays. The fly cage can be made into a 60-80 cm cube with thick iron wire, covered with white gauze, with an operation opening on one side. The size of the opening is suitable for placing food trays and egg trays. A sleeve is made of black cloth at the opening to prevent flies from escaping. Each food tray is equipped with 3-4 medium trays for flies to lick the feed. A small water cup is placed in each cage, and a sponge pad is placed in the cup. An egg-laying primer is placed in the egg-laying tray to induce female flies to lay eggs. The eclosion tray is used to hold the quickly eclosing fly pupae during the generation change.

3. Feeding and management. ① Breeding fly feed: grind the 4-day-old maggots cultured aseptically, add 60% brown sugar, 2% yeast powder and appropriate amount of water to make a paste, and add 0.1% sodium benzoate. ② Egg-laying primer: take bran and add 0.03% ammonium bicarbonate and mix well, or use chicken feces is better. ③ Stocking density: 50,000 to 80,000 flies can be raised per cubic meter of fly cage, usually 10,000 to 20,000. ④ Management method: When the breeding flies are found to have mated, they should be placed in the egg-laying tray 2 days later. The egg-laying primer should be loose and evenly spread, with a thickness of 1 to 2 cm. Breeding flies lay the most eggs between 8 and 15 o'clock every day, and the egg-laying tray should be replaced in time. ⑤ Wintering seed preservation: The fly pupae that have been selected and removed from the inferior can be stored in a container with appropriate temperature, humidity and loose feces, and placed indoors and covered with straw to keep warm and moist.

Main facilities and management of maggot breeding

1. Facilities for raising maggots. At present, there are three forms of maggot raising, namely, maggot raising room, vertical maggot raising rack and maggot raising basin. Maggot raising room can be raised in semi-underground form indoors. The bottom and wall of the pool should be plastered with cement to prevent seepage and prevent maggots from climbing up. It is best to paste a layer of 3 cm thick glass on the four walls. A 5-8 cm wide small ditch should also be set around the pool to prevent ants and adjust humidity. The room temperature should not exceed 35℃. The vertical maggot raising rack can be welded with steel bars or made of cement into a three-dimensional or stepped type. The height of the maggot raising basin should be 10-20 cm (the surface of the basin should be smooth) and the internal filling material should be 5-8 cm.

2. Preparation of raising feed: 50% to 60% fresh chicken manure or pig manure, 35% to 45% bran, 5% coarse bran, mix the three materials evenly, and prepare a raising feed with a water content of about 65%, and adjust the pH value to 6.5 to 7.

3. Inoculate and hatch. Inoculate 1 gram of fly eggs per kilogram of culture medium and evenly spread them on the surface of the culture medium in the maggot breeding basin. After 8 to 12 hours, they will hatch into maggots. Keep the temperature of the culture medium stable and no water should be accumulated.

4. Separate and collect. Collect the maggots when they turn yellow after 5 days. Take advantage of the maggots' fear of light, place the maggot breeding basin under strong light, use a dung shovel to move the maggots from the bottom, and finally remove the nutrients on the upper layer and sieve them out with a 10-16 mesh sieve. Wash the maggots and use them fresh or process them for later use.

5. Usage of fly maggots. In addition to feeding livestock and poultry directly, the remaining fresh maggots produced daily can be dried in an oven at 200-250℃ for 15-20 minutes, and then ground into maggot powder for winter ingredients. The general addition amount is about 5%.

3. What should I do if the meat buried in the soil of the flowerpot starts to grow maggots?

I used the EM fermentation liquid I bought on Taobao to ferment kitchen waste, but the effect was not as good as advertised. After burying the kitchen waste in the soil, there were a lot of insect eggs on the surface of the soil. I couldn't figure out whether the insects would have any impact on the crops after they grew.
