Feeding method of fly maggots
1, plastic pot (barrel) propagation method
This method can be produced in small quantities, and each plastic pot produces about 1 ~ 1.5 kg of fly maggots. Can I feed the pheasant 50? 75. Put fresh animal viscera, dead mice, etc. Where there are many flies, let the flies lay eggs on it, release them early and collect them later, and put the collected fly eggs into a large basin with a diameter of 6 cm (or a plastic bucket with a diameter of 30 cm). Sprinkle water into the plastic basin, keep it moist and cover it. After 2-3 days, maggots will grow out. This method can breed fly maggots in the wild without introduction. Feeding maggots, the food intake is from less to more, that is, putting fresh chicken manure and pig manure into a basin according to the ratio of 1: 1, feeding 1 kg in a plastic basin with a diameter of 60 cm every day (barrel feeding is halved), and then spraying 100 ml of 3% sugar water (or sugar mill waste liquid and molasses). Feeding method: pour the water into the basin, stir it gently with a wooden stick, remove the fresh maggots floating on the water surface, clean and disinfect them, and feed them directly to the animals. The residual water is poured into biogas digesters or cesspits for fermentation and sterilization. If it is used to feed turtles, eels and fish, it can be poured into the pond with manure to feed.
2, outdoor floor culture method
This method is suitable for large-scale breeding in farms.
(1) Selection of breeding grounds. In places far away from houses and close to livestock houses, a piece of land should be leveled and compacted, and it should be kept above the water surface as a breeding surface. The area of a culture surface is about 4 square meters. The number of culture surfaces is determined according to the feeding scale.
(2) Fabrication of the bracket. Make a scaffold with iron or wood to cover the culture surface, with a height of 50 cm. Cover both sides of the scaffold with a layer of kraft paper to block the direct sunlight. Then put a layer of plastic cloth around the bracket (the east and west sides can be lifted) to make a cover to keep warm and moisturize. The scaffold is as big as the culture surface, movable and removable at any time, which is convenient for feeding and taking maggots.
(3) spread manure on the cultivation surface, mix fresh chicken manure and pig manure evenly according to the ratio of 1: 1, spread them flat, wet them with water before spreading them flat, spread the manure loosely and evenly on the cultivation surface with a thickness of 5- 10 cm, which is thin in hot days and thick in cold days, and finally move the bracket to spread the manure layer.
(4) Within 24 hours after laying manure, spray water several times according to the humidity requirement to keep the surface of manure layer moist, so as to facilitate flies to lay eggs and hatch eggs. If you spray water with chicken manure; If pig manure is used alone, three ten thousandths of ammonia or ammonium bicarbonate can be added to the water to attract flies to lay eggs. After the flies lay eggs in the dung layer for a day and night, the plastic sheets on the east and west sides of the bracket can be put down and pressed around, and the temperature in the hood can be maintained, so that the fly eggs can hatch in the dung layer.
(5) The fly eggs can hatch into maggots at 25℃ for 8 ~12 hours. After maggots hatch, water should still be sprayed on the dung layer according to the evaporation of water, but there should be no water in the dung layer to prevent maggots from choking. The plastic sheets on the east and west sides of the opening and closing bracket are used to adjust the temperature in the cover between 20 ~ 25℃. In the late growth stage of maggots, it is better to reduce the humidity of dung layer, which is wet inside and dry outside.
(6) The maggots can be used after hatching for 6-9 days. In principle, a large number of maggots cannot be pupated. Because maggots are afraid of direct sunlight, when taking maggots, they can remove the bracket and let the sunlight shine on the dung layer, so that maggots can drill to the bottom of the dung layer, shovel the dung on it, then peel off the dung and maggots at the bottom and put the chickens in for pecking. This is the easiest way to collect maggots. After the chicken eats the maggots, gather the feces in piles, add 50% fresh feces, mix them evenly, water and flatten them, and then raise the maggots again. The method can be carried out at the temperature above 5℃, and the temperature below 65438 00℃ can be improved by adding 20% horse manure for fermentation. If 500 grams of maggots are produced per square meter and each chicken needs 20 grams per day, then 4 square meters of breeding area can produce 1 cycle to feed 100 chickens 1 day.
3, soybean milk blood single tube propagation method
This method is suitable for breeding in seedling markets or food processing plants that specialize in breeding and produce a small amount of fly maggots in urban areas.
First, put 1 vat in a place where there are many flies, grind 500 grams of soybeans into soybean milk and pour it into the vat, then add 10 kg of water and mix well, then pour 2.5 ~ 3 kg of fresh pig blood or cow blood, and then add 5 kg of rice washing water and mix well, so that flies can feed and lay eggs in the vat, so as to catch maggots and feed them to animals. Feeding once can be used continuously for 2 ~ 3 months. The requirement of this maggot raising method is to keep 40 ~ 50 kilograms of soybean milk blood in the tank, and pay attention to adding it when the volatilization of soybean milk blood decreases; In addition, the jar must be placed where there are many flies.
4. Multi-cylinder fecal cycle propagation method
This method is suitable for small feed farms, small fish ponds and fry farms. ..
Take 12 tanks that can hold 30kg of water, and arrange them in two rows in a place where there are many flies. The numbers are 1 ~ 12 in turn. 1 day, put 1 kg fresh chicken manure, 1 kg fresh pig manure, 500g human urine, 2 dead rats (frogs) or 250g animal carrion and internal organs into 1 cylinder, and then add urine water every day to keep it moist. On the second day, according to the method and quantity of the first day, put the No.2 tank into the pond, put the No.3 tank into the pond on the third day, and so on. /kloc-put the 12 tank into the pond on 0/3, then pour the adult maggots in the 1 tank into the pond to feed the fish. If you feed livestock food, you can fill the tank with water, let the maggots float to the surface and take them out to feed. Then dump the manure water, clean the tank, and feed it again according to the practice of 1 day. The second tank was taken on 14 day, and the third tank was taken on 15 day, so that fresh fly maggots were continuously obtained and used as feed for livestock and poultry and live bait for animals.
5, platform introduction pond propagation method
This method is suitable for small-scale farms.
(1) 1 m2, several small square cement pools with a depth of 5cm will be built. Build a feeding platform with a height of 1 200 cm by the pond, and then inject water into the pond. The water level is slightly lower than the feeding platform, and the pond is covered with a sunshade canopy with a height of1.5 ~ 2 m.
(2) Put 500 grams of leftover meat, skins, intestines or internal organs discarded by slaughterhouses on the feeding table, or 300 grams of animal carcasses such as rats and rabbits to lure flies to feed and lay eggs.
(3) Put the culture material placed on the platform for 2-3 days into the pool water and stir for a few times, shake off the young maggots and fly eggs attached to it into the water, and then put the culture material back on the platform to lure the flies to lay eggs again.
(4) Put 2kg of fresh pig and chicken manure or 4kg of human manure into each pond, feed it for 24h, and then feed it after the fly maggots decompose the floating manure.
(5) Keep in the pond for 4-8 days, and catch the adult maggots in time when they climb to the edge of the pond to prevent the adult maggots from escaping. Take out the maggots with a colander or gauze, wash them with clear water and feed them while they are hot.
(6) clear the pool. When the insoluble dirt layer at the bottom of the pond exceeds 15 cm, which affects maggot fishing, the dirt at the bottom of the pond can be removed at one time and new water can be injected.
Twenty-four ponds were built and two ponds were fed every day. By circulating feeding, 6 kilograms of fresh maggots can be produced every day, which can feed 12 pigs or 300 chickens.
6, pond hanging basin feeding method
Rows of brackets are arranged at the distance of 1 m from the bank of the pond, and 1 ~ 2m intervals are used to hang1washbasins with a diameter of 400 meters in rows on the pond surface of special economic animals, and the basin is about 20cm away from the water surface. Put the same amount of pig manure and chicken manure in the washbasin, wet it with water, sprinkle a few drops of ammonia water, and then put a few dead fish or mice on the basin surface to lure flies to lay eggs. Houseflies or other wild flies will fly to the basin to feed and lay eggs. After a week, the maggots will crawl out of the basin and fall into the water, where they will be directly eaten by the animals in the pond. By adopting this method, the equipment is simple and the operation is simple. Two kilograms of feces can produce 500 grams of fresh maggots. Several points should be paid attention to in gymnastics: first, the basin should not be too deep, and 10 ~ 15 cm is appropriate; Second, it is best to use a plastic basin with 2 ~ 3 water holes at the bottom to prevent water from accumulating in the basin during heavy rain; 3. After the basin is filled with manure, it is best to cover 3/4 of the basin surface with lotus leaves or kraft paper, leaving14 of the basin surface for dead animals to attract flies, which is beneficial to the growth and development of maggots. Fourth, high-temperature water evaporates quickly in summer, so it is necessary to check and water it frequently to keep the culture material moist.
