Flies are one of the "four hazards" in the spread of diseases. However, with the development of science and technology, its amazing fertility and abundant nutrients will become an inexhaustible top protein feed for the breeding industry. Development of medicine, health care, biochemical, pesticide and chemical products. It was determined that dried fly maggot powder contains 59% to 65% of crude protein, 12% of fat, and 43.83% of total amino acids, 3.3 times that of fishmeal. Adding appropriate amounts of fresh wolfberry to the feed increased the yield of fish by 22%, and the egg production rate of the fed chicken increased by 17% to 25%. The growth rate of the fed pigs increased by 19.2% to 42% and the feed was saved by 20% to 25%. Most of the farms in the former Soviet Union have a breeding farm. Because of simple farming techniques, low cost, and significant economic benefits, it is also very practical for the vast number of farmers and farms in China.
%26nbsp1. Living habits of Musca domestica Musca domestica is divided into four stages: eggs, quail, flies, and flies. Each generation needs 12 to 15 days, and 24 generations can breed each year. . Among them, eggs are hatched into quail after 12-24 hours; maggots are feathered into quails after 5-7 days; nymphs are adultated into 3-5 days. After the male flies, they die, but the female flies can live for 30--60 days, and can produce 1500 eggs for a lifetime. If the conditions are suitable for a pair of house flies, 200 million of the offspring can be bred in the summer.
%26nbsp2, fly breeding 2.1 species of fly house. The indoor air is required to be fresh, the temperature is maintained at 24-30Â°C, the relative humidity is 50%--70%, and the light is lighted for more than 10 hours per day. There are fly cages, cages, hygrometers, and warming ventilation to prevent escape. 2.2 fly cage production. Use coarse wire or bamboo strips to make 50 cm square fly cages and external plastic gauze covers, one of which has a diameter of 20 cm in the operating hole, and the hole is slit by a 30 cm long cloth tube. tight. Three cages are placed on the cage three-dimensionally, and 1-1.5 million can be raised per cage. 2.3 The source of fly species. The first batch of sterile flies can be introduced from the demonstration base and can also be cultivated by wild flies on their own. The method is to sterilize flies that have been bred or excavated, and then select a large population (not bulkhead flies) to be placed in the cages for emergence. Aseptic fly species. 2.4 Feeding methods. The purpose of cage culture is to allow females to concentrate their eggs. There are four kinds of discs or cylinders with different functions in the cage: one is a water tray: it is used exclusively for drinking water of the species fly and it is changed every day; the second is the food tray: it is transferred with a paste, brown sugar, yeast, preservatives, and water. The nutrient foodstuff is changed every day; the third is the spawning cylinder: the tank is filled with bran water and attractant mixture to lure the female flies to lay eggs, and the material and eggs are transferred into the larvae to cultivate the pots every day; the new material is replaced; and the fourth is the emergence. Cylinder: For the new generation, put into the soon-to-be-emerged species. 2.5 Species fly is eliminated. The all-in, all-out breeding method is to kill all the 20-day-old seed flies, and then they are processed into flies. The fly cages are then treated with disinfection and then used to cultivate the next batch of new flies.
%26nbsp3. Feeding 3.1 breeding rooms. Similar to the breeding house, the room temperature is maintained at 26--35Â°C, and the humidity is 65%--70%. There are facilities such as eucalyptus pods, breeding bowls, temperature and humidity meter and heating. Larvae do not need light when they are afraid of light. 3.2 Feeding methods. The nursery bowl is first loaded with a mixture of 5-8 cm thick mixed diet prepared mainly from livestock manure, with a humidity of 65%--70%, and then the ratio of 1 g of fly eggs per 1 kg of food material. 8--12 hour eggs hatch into quail, 0.5 kg per 1 kg of pig manure. 3.3 Separation of terpenes. After five days of breeding, the quail is already mature. Except for the retention of the seeds, the quail should be collected and used. The method is to use â€œstrong light screening methodâ€ or â€œanoxic methodâ€ to force the escaping from the food to separate. After the fresh broth is fed, it can be dried and processed into glutinous rice flour. Agent fish meal can be used to prepare mixed feed. 3.4 Stay selected. After mashing into mash, the screen is used to separate the mash, and then a large fullbody is selected for seeding; temporary storage can be stored in the refrigerator for 15 days; winters should be moved into the indoor insulation for winter.
