1. What can I raise with 2,000 yuan?Raising flies can support tens of thousands of people~ 2. The road to wealth: what to raise?Raising maggots to feed chickens is a good way to get rich 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%. References: 3. Can you make money just by breeding flies?The benefits are very impressive! ! Since ancient times, fly maggot protein food has always been a hot topic of discussion. As early as the Ming and Qing Dynasties, the West... After years of careful research, American scientist Lind first proposed in 1919 that flies could be used to turn human and animal feces into animal eggs. 4. Can maggot farming make money?Your suspicion is justified! In addition to feeding chickens, maggots currently have no other special uses. Moreover, the utilization period of maggots is short. If they are not fed to chickens in time, they will emerge as flying flies and need to be kept in a covered place. Raising them is far less convenient and affordable than mealworms. Chinese people generally dislike maggots, so it is unlikely that they will have as broad an application prospect as mealworms in the near future. Investing in maggot breeding should be considered carefully. |
