CATDOLL : CATDOLL: Does breeding fly maggots have a bad smell?

Does breeding fly maggots have a bad smell?

It can be free of odor and needs to be treated with available bacterial liquid. The eggs of flies can be made into an egg collector, which can be made into a wooden box. Do not lay eggs on food, and must be put into the egg collector in time. The egg collector has substances that attract flies to lay eggs, so it is better to distinguish the branches.

The reason why rotten things smell bad is that bacteria produce a lot of incomplete metabolites, which will emit various odors. In order to avoid odors, disinfection must be done before breeding fly maggots to kill bacteria. Killing bacteria in the culture medium is not only conducive to environmental cleaning, but also conducive to the effective use of the culture medium by larvae, reducing the consumption of organic matter in the culture medium by bacteria, which has a great effect on improving the yield.

No odor, usually fermented chicken manure is used

How to raise maggots

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 food. 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 the branches and collect them. 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%.

Maggots are the larvae of houseflies. The body color of maggots changes from transparent, milky white to creamy yellow until they mature and pupate. Maggots have three instars: the first-instar larvae are 1 to 3 mm long and have only the posterior spiracles. After molting, they become the second-instar, 3 to 5 mm long, with anterior spiracles and 2-lobed posterior spiracles. After molting again, they become the third-instar, 5 to 13 mm long, with 3-lobed posterior spiracles. The third-instar larvae are oblong-conical, with a pointed front end and a truncated rear end, without eyes or bright foot cavities. They like to drill holes, are afraid of strong light, and live in dark places away from light in breeding habitats all day long. Maggots are high in crude protein and crude fat, rich in nutrition, and are an ideal food for forest frogs.

The optimum environment temperature (culture medium temperature) for fly maggots is 34-40℃, and the development period is 3-3.5 days. When the temperature is 25-30℃, the development period is 4-6 days; when the temperature is 20-25℃, the development period is 5-9 days; when the temperature is 16℃, the development period is as long as 17-19 days. The minimum development temperature is 8-12℃, and death occurs when it is higher than 48℃.

The suitable humidity for 1st to 2nd instar maggots is 61% to 80%, and the best humidity is 71% to 80%. The suitable humidity for 3rd instar maggots is 61% to 70%. If the humidity is higher than 80% or lower than 40%, they cannot develop normally, rarely pupate, and may even die.

Air circulation is conducive to the growth and development of maggots. In garbage dumps, maggots are often distributed in corners and bases of walls with large gaps. Exhaust fans should be installed in the breeding room, and screens should be installed on the exhaust fans for filtering to prevent flies from escaping from the fan outlet. Doors and windows should be sealed with wire mesh to prevent snakes, rats and other harmful creatures from entering the breeding room.

Fly maggots are omnivorous and like to eat decayed and fermented organic matter. Animal and plant feeds and proteins in microorganisms are all feeds that fly maggots like to eat. When the third-instar fly maggots mature, they stop eating, leave the breeding place, and burrow into the nearby loose soil to pupate.

In artificial breeding, livestock and poultry manure is mainly used as the base material, and fresh is better. Livestock and poultry manure must be fermented before use. Pig manure, chicken manure, tofu dregs, wheat bran, livestock and poultry scraps, etc. can be fermented and used as the base material for fly maggot breeding.

The base material can be mixed according to the following formula: 80% pig manure, 20% wheat bran; 60% pig manure, 40% chicken manure; 75% pig manure, 25% tofu dregs; 100% fresh pig manure; 50% chicken manure, 25% pig manure, 25% tofu dregs. If the manure is too wet, a small amount of wheat bran can be added. According to the existing conditions, see which base material is easy to obtain and low in cost, and prepare it flexibly. Add EM live bacteria to the prepared manure, add 5 kg of EM bacteria per ton, then cover it with plastic film, turn the manure once on the third day, and then add 3 kg of EM bacteria to the manure to make the pH of the manure reach 6.5-7. If the pH is higher than 7, add wine lees and vinegar; if it is lower than 6.5, add lime water. It can be used after fermentation for 2 days. The water content of the base material is about 70%, and it is better to pile it up to 20 cm high without loosening or deformation.

After the base material is fermented, it can be sent to the maggot breeding room to breed fly maggots. A rectangular maggot breeding pool with an area of ​​1.5 square meters can be built in the maggot breeding room. The fermented base material is piled in the pool in a long strip with a thickness of 10 to 15 centimeters. Let the adult flies lay eggs directly on the base material, and cover them slightly with base material or feed after laying eggs to prevent the fly eggs from drying out. When the room temperature is 25 to 35 degrees Celsius, the egg mass will hatch into maggots after eight to ten hours. If the base material is too dry, sprinkle a small amount of water on it. The amount of water added should be appropriate so that the water does not flow out of the manure pile.
