CATDOLL : CATDOLL: I would be very grateful if you could give me some advice on maggot farming.

1. The yield is closely related to the management level. Generally speaking, the bioconversion rate is about 15-30%, which means that you can produce 15-30 kg of fresh maggots for every 100 kg of culture medium.

2. The cost can be adjusted according to the existing conditions, and the existing equipment can be used as much as possible. It is nothing more than the site, feed (brown sugar and milk powder), mosquito nets, etc.

3. Small-scale breeding is generally used as protein feed for broiler chickens, and few people buy it. The cost of chicken produced in this way is not lower than that of using the formula feed provided by the manufacturer, and may even be higher. It is necessary to find a good sales channel for chicken.

4. The key technology is to control the temperature, humidity and breeding density, and don't let flies fly everywhere.

Here are some breeding methods and related websites:

There are many ways to raise flies. Here are two methods of raising flies in plastic greenhouses:

One is to set up a three-dimensional gauze in the greenhouse and raise flies in the net; the other is to raise flies in the greenhouse, stack a certain amount of straw and straw rope in the greenhouse, and regard each greenhouse as a cage. This method requires more investment, occupies a large area, and has a low stocking density. The breeding method of setting up a gauze in the greenhouse generally builds a plastic greenhouse with a length of 20 meters, a width of 4 meters, a low wall height of 2 meters, and a high wall height of 3 meters, and a gauze with 3 layers.

We choose red-headed flies as the breeding species. Red-headed flies are the kind commonly seen in farm toilets with a red head and a bright green back. They are called differently in different places. Because their heads are red, we call them "red-headed flies."

How to raise adult flies:

Breeding cage: The cage frame is 50×50×50 cm in size, with a gauze of the same size tied on it. In the center of one end of the gauze is a cloth sleeve with a diameter of about 20 cm and a length of 33 cm, which is used to take flies out and change food.

A feeding dish (7-9 cm in diameter) is filled with sugar for adult flies to eat, or a piece of water-soaked foam plastic is placed inside it to provide a water source for adult flies, which can also be used to attract eggs.

8,000 to 10,000 adult flies are raised in each cage. Whether it is newly collected adult flies or adult flies that have just emerged, sugar and water must be provided in time to prevent them from starving to death. Adult flies lay eggs 3 to 5 times in their lifetime, up to 10 times, and each time they lay 100 to 150 to 300 eggs.

Larvae rearing method:

First place the feed in the breeding box with a thickness of no more than 4 cm. Then use a worm shovel to slowly place the trapped fly eggs (one-day-old larvae) on the feed in the breeding box. The young maggots will slowly disperse and drill into the feed. When the larvae eat the feed, they generally eat from top to bottom. If the humidity or temperature in the box is high, or the feed is insufficient, or the insect density is too high, the young maggots will crawl out. The breeding staff should check at any time and take timely measures such as adding feed or lowering the temperature or humidity.
