What are the benefits of raising maggots?

Natural temperature conditions are necessary for maggot breeding.

When the temperature is below 20℃, flies stop breeding or hibernate, not eating or moving. Plastic sheds can only be used for seasonal breeding. In late autumn, severe winter, and early spring, the temperature does not meet the requirements, and breeding in the shed is futile.

Maggot feed The feed for productive breeding of maggots must be cheap waste, preferably chicken manure produced by professional chicken farmers. Calculated based on 3 catties of chicken manure to 1 catties of maggots, productive breeding requires a lot of feed. If you buy soy sauce residue, tofu residue or other waste, the cost is too high, and the result is often not worth the cost.

It is best to have your own poultry or fish farming professional household to carry out productive breeding of fly maggots with self-consumption ability, so as to reduce the feed cost of poultry and fish and improve economic benefits.

Fly maggot breeding is largely unhygienic, so when choosing a breeding site, pay attention to the following points:

Stay away from residential areas. Chicken manure or other waste piled up in the yard will allow adult flies to enter the house and bite and crawl around, affecting human health.

Pay attention to the year-round wind direction. Pay attention to the local year-round dominant wind direction and set up the maggot breeding farm on the leeward side of the chicken farm to prevent the odor from drifting into the breeding room and chicken house, affecting the healthy growth of breeders and chickens.

Keep away from water sources. Fly maggot farms must be far away from self-supplied water sources and public water sources to prevent sewage from seeping into the ground, causing water quality deterioration and affecting the water use of chickens.

Waste dumps and productive maggot breeding sites must have dedicated areas for the storage of chicken manure and maggot breeding waste to prevent environmental pollution.

The construction of breeding rooms and sheds The area of ​​the insulation room and shed is calculated as 1 square meter for every 1 kilogram of maggots produced. Rooms and sheds that are too large are not conducive to heat preservation, and too small cannot guarantee the output. This is a major problem in maggot breeding, which involves investment issues. If funds permit, a cold-proof insulation room can be built for year-round breeding; if funds are insufficient, greenhouse-style seasonal breeding can be carried out. Simple outdoor breeding is affected by temperature and rain. The breeding time in the south is longer and that in the north is shorter. This type of breeding can neither guarantee the output nor harm environmental hygiene, so it is not recommended. The following points should be paid attention to when constructing sheds for productive breeding:

To ensure that the indoor temperature of the greenhouse is above 25℃, the indoor walls should be of a certain thickness, the doors and windows should be tight, and there should be heating and temperature control facilities indoors. The temperature of the plastic greenhouse is too high in summer, and it is difficult to reach 25℃ in cold seasons, so it is not suitable for breeding.

When breeding in a rainproof and sun-proof shed, pay attention to rain protection to avoid damaging the breeding environment of fly maggots. In midsummer, pay attention to avoid sun exposure to prevent the fly maggot feed from drying up and causing the maggots to die.

The specific structure, scale and shape of rooms and sheds can be adapted to local conditions and do not have to be forced to be consistent, as long as they are applicable.

Productive breeding management of maggots can be roughly divided into two parts: inducing flies to lay eggs and the growth of maggots.

Due to the instinct of safe hatching, female flies usually lay eggs in a quiet or sheltered place rich in nutrients. To understand this habit of female flies, you can use plastic square plates, cans and other containers, put nutrients (meat bones, leftover soup, fish offal, watermelon rinds, wheat bran, sugar solution and other waste) in them, and place them in a quiet place to lure flies to lay eggs. When the eggs hatch into maggots, you can move them into chicken manure to let them grow.

When feeding and managing fly maggots during their growth process, it is important to understand that after the maggots mature, they no longer need to be fed with feed, but begin to crawl outward into the soil to pupate, and the maggots should be collected or caught in a timely manner.

Fly maggot breeding can be divided into two types: dry and wet. Dry breeding is: spread chicken manure on plastic sheeting or cement floor, 80 cm wide, 10-15 cm high, and unlimited length. After the fly eggs or hatched larvae are moved on, water is sprinkled to maintain a certain humidity, and the eggs or larvae can hatch and grow. Wet breeding is: build a non-leaking pool of 30 cm deep, 60-80 cm wide, and unlimited length in the room or shed, put water in the pool, put chicken manure in and stir it into a thick slurry, move the fly eggs in, and it can hatch into maggots and grow. Regardless of dry or wet breeding, when the fly maggots grow, the maggot manure should be cleaned in time and new chicken manure should be replaced regularly to increase production.

Processing and storage of fly maggots The collected or fished fly maggots should be put into hot water to kill them in time, then fished out and dried in the sun (dry), or directly mixed into corn crushed feed and fed in time. Wet maggots mixed into corn flour should not be left for a long time to avoid mold and deterioration.

The daily output of fly maggots is high, and the moisture content must be controlled after drying to facilitate long-term storage. When processing fly maggots, rotten and deteriorated dead maggots must be picked out to avoid affecting the quality of maggot powder.

What should be done first to raise fly maggots?

1. Necessary conditions for fly maggot breeding Natural conditions: Temperature is one of the necessary conditions for fly maggot breeding. Below 25℃, flies stop breeding or enter hibernation, not eating or moving. Plastic sheds can only be used for seasonal breeding. In late autumn, severe winter, and early spring, the temperature is not high enough to meet the requirements, so breeding in the shed is futile.

Maggot feed: The feed for productive breeding of maggots must be cheap waste, preferably chicken manure produced by professional chicken farmers. Calculated based on 3 catties of chicken manure to produce 1 catties of maggots, productive breeding requires a lot of feed. If you buy soy sauce residue, tofu residue or other waste, the cost is too high and the result is often not worth the gain.

Self-consumption capability: Productive fly maggot breeding products must have self-consumption capability. Currently, there are not many departments that purchase fly maggot products, and there are not many deep processing units for fly maggots and pupa shells. Therefore, to engage in productive fly maggot breeding, one must be a professional poultry or fish breeding household that can produce and consume by itself, so as to reduce the feed cost of poultry and fish and improve economic benefits.

2. Site selection for breeding sites. Fly maggot breeding is detrimental to hygiene to a great extent. Therefore, the following points should be noted when selecting a breeding site: Stay away from residential areas: Chicken manure or other waste is piled up in the yard, and adult flies enter the room to bite and crawl, affecting human health. Pay attention to the perennial wind direction: Pay attention to the local perennial dominant wind direction, and set up the fly maggot breeding farm on the leeward side of the chicken farm to prevent the odor from drifting into the breeding room and the chickens, affecting the healthy growth of the breeder and the chickens. Stay away from water sources: Fly maggot breeding farms must be far away from self-supplied water sources and public water sources to prevent sewage from seeping into the ground, causing water quality deterioration and affecting the water use of the chickens. Waste dumping site: Fly maggot production breeding sites must have a dedicated site for the stacking of chicken manure and fly maggot breeding waste to prevent environmental pollution.

3. The construction of breeding rooms and sheds. The area of ​​the insulation room and shed is calculated as 1 square meter for every 1 kilogram of maggots produced. Rooms and sheds that are too large are not conducive to heat preservation, and too small cannot guarantee the output. This is a major problem in maggot breeding, which involves investment issues. If funds permit, a cold-proof insulation room can be built for year-round breeding; if funds are insufficient, greenhouse-style seasonal breeding can be carried out. Simple outdoor breeding is affected by temperature and rain. The breeding time in the south is longer and that in the north is shorter. This type of breeding can neither guarantee the output nor harm environmental hygiene, so it is not recommended. The following points should be paid attention to when constructing sheds for productive breeding:

Cold protection and heat preservation: To ensure that the indoor temperature of the greenhouse is above 25℃, the indoor walls should be of a certain thickness, the doors and windows should be tight, and there should be heating and temperature control facilities indoors. The temperature of the plastic greenhouse is too high in summer, and it is difficult to reach 25℃ in cold seasons, so it is not suitable for breeding.

Rain and sun protection: Pay attention to rain protection when breeding in the shed to avoid damaging the breeding environment of fly maggots. In the midsummer season, pay attention to avoid direct sunlight to prevent the fly maggot feed from drying up and causing the maggots to die.
