CATDOLL : CATDOLL: Animal feed breeding fly maggot breeding

Fly maggot breeding: ferment manure → send to maggot room → pile into strips → place egg collecting materials → cover egg masses after laying eggs → retain water and heat to breed maggots → automatic separation → collect adult maggots → comprehensive utilization → shovel out residual manure → repeat the production cycle.

(1). Manure formula and fermentation: Formula 1: 70% fresh pig manure (within 3 days), 30% chicken manure (within one week); Formula 2: 100% fresh pig manure from slaughterhouse; Formula 3: 60% pig manure, 30% bean dregs, 10% bran; Formula 4: 70% chicken manure, 30% distiller's grains. Fermentation method: 1 ton of manure, 20 kg of health liquid, 5 kg of corn flour, mix well with manure in the fermentation tank, cover with plastic film and seal tightly, and use after 1 to 3 days of fermentation (short in summer and long in winter).

(2) The fermented manure is sent to the maggot room, and three strips are piled in each pool, each strip is 0.8 meters long, 0.2 meters wide, and 0.15 meters high. The time for feeding manure is: 8-9 o'clock every day in winter and spring, and 16-18 o'clock in the afternoon in summer and autumn.

Maggots

(3) Place egg-collecting materials on the dung pile, three small piles for each maggot. The formula of the egg-collecting materials is: 1 kg of wheat bran, 2 liang of fish meal, 3 liang of peanut bran, and 1.5 kg of water, calculated based on 100 kg of dung. Mix well and place on the dung pile. After placing the egg-collecting materials, it is forbidden to walk around in the maggot room.

(4) Under normal circumstances, after placing the egg-collecting material, flies will gather on it to lay eggs. At 8 p.m., a small amount of egg-collecting material is used to cover the egg masses exposed outside, as provided by fly maggot breeding technology.

(5) At room temperature of 25-35℃, the egg masses generally hatch into small maggots after 8 hours. If the manure pile is found to be too dry, sprinkle a small amount of water on it. The small maggots will first eat the egg collection materials, and then drill into the manure pile to grow; 24 hours after hatching, the manure pile that was previously neatly stacked has been eaten and scattered by the maggots. At this time, you should pay attention to maintaining the moisture of the manure pile. When you find that the manure pile is dry, you should add water in time. At this time, it is best to add water with pig pen water treated with health liquid. The amount of water added is best not to see water flowing out of the manure pile; as the maggots continue to grow, the manure pile has completely become loose. 72 hours after the maggots hatch, some of the first mature maggots begin to crawl out of the manure pile and fall into the maggot collection bucket. The peak period of crawling out is 72-96 hours. At this time, the manure pile scattered by the maggots should be piled into a large pile twice a day. The purpose is to clean and prevent the scattered manure from blocking the edge of the pool and preventing the maggots from crawling into the maggot collection bucket smoothly. Generally, on the fourth day after the manure is put in, the maggots in the manure pile have basically crawled out (a small amount of maggots that have not crawled out are shoveled out and piled in the chicken place to let the chickens help clean up the remaining maggots), the residual manure is shoveled out, and the newly fermented manure is put in again, and the production cycle is repeated. At 10 o'clock every morning, it is required to spray all places in the maggot room once with a 50-fold diluted health liquid to eliminate odor and sterilize.

(6) Maggots should be collected from the maggot collection bucket twice a day, at 8 a.m. and 5 p.m. respectively. When collecting maggots, wear a pair of leather gloves and then grab them. Maggots can be fed directly to economic animals without disinfection.

(7) A 40-square-meter three-dimensional fly maggot breeding technology room is required to have more than 300,000 breeding flies, of which 80% are red-headed flies and 20% are small house flies. On average, 1 kg of fly maggots should be kept every three days when the fly maggots are collected and placed in a special hatching pool or a basin to allow them to pupate and hatch (it takes about 72 hours for pupation and about 72 hours for pupae to hatch into flies) to ensure the number of breeding flies. The lifespan of male flies is generally only 7 days, while the lifespan of female flies is generally 15 to 25 days.
