CATDOLL : CATDOLL: What should you pay attention to when raising chickens with maggots?

When raising chickens with fly maggots, pay attention to the following points:

1. The total amount should be 20% of the feed, and should not exceed 30%. If you feed too much, the chickens will eat maggots and then eat them again. The most terrible thing is that it may cause the egg white to crack and the chicken's abdomen to swell and accumulate water, leading to sudden death.

2. It is not suitable to feed young chickens with immature maggots. It is not the common saying that "small maggots are fed to young chickens, and big maggots are fed to big chickens". This is because the small maggots have undigested bacteria in their stomachs and on their bodies. Mature maggots no longer eat, and there are no black threads in their stomachs. The dirt on the bodies of mature maggots that crawl out has also been wiped clean.

3. Fasting chickens should eat some other feed first, and then feed maggots, which has a high utilization rate.

Raising chickens with fly maggots can promote production and increase egg production, but you must pay attention to the above 3 points, otherwise it may cause accidents.

You can go to Sodong Mall, which can teach you how to raise chickens professionally. The veterinary medicines are also easy to use and inexpensive.

1. The living habits of flies

At a temperature of 20-30 degrees Celsius, the pupa develops over 5 days, from soft to hard, from beige, light brown, dark brown to black, and finally the adult fly breaks out of the shell from the front end of the pupa. The newly emerged adult fly cannot fly, and after 1 hour, it spreads its wings and begins to eat and drink. The adult fly is active during the day and stays still at night. After 3 days, it matures sexually, and the male and female begin to mate and lay eggs. The peak egg-laying period is 1 to 8 days old, and the ability to lay eggs is basically lost at 25 days old.

Fly eggs hatch into maggots in half a day to a day, and usually turn into pupae on the fifth day. A generation of flies is about 28 days. Temperature and maggot feed have a great influence on the growth and development of maggots. Generally, the room temperature is within the range of 20~30℃. The higher the temperature and nutrients, the faster the maggots grow and develop, and the larger the pupae they become.

2. Breeding of Flies

The breeding flies should be raised in a fly house. The size of the breeding fly house can be built according to the needs. It can also be modified from an old house. Glass and screens should be installed on the doors and windows to facilitate temperature adjustment. Fans should be installed on the walls to adjust the air. There should be heating equipment in the room to keep the temperature at 20~23℃ in winter and the relative humidity in the room at 60%~70%. Black curtains should be installed on the passage to prevent the breeding flies from escaping. There are breeding racks in the room, divided into three layers: upper, middle and lower. The breeding racks are made of iron or wood.

Each shelf is placed with a fly cage made of nylon gauze, which is 100 cm long and 80 cm high. The breeding flies are kept in the cages. Each cage can hold 12,000 breeding flies. Each cage is covered with cloth sleeves to facilitate adding feed, water and egg collection. 12,000 adult flies are fed 20 grams of milk powder every day. The feed is placed in a feed basin with a gauze pad, and the adult flies are allowed to stand on the gauze to eat.

Feed and water should be changed once a day. Gauze should be placed in the water basin, wet wheat bran should be placed in the egg-laying cage for the fly to lay eggs, and eggs should be collected from the fly cage once a day and sent to the maggot room for breeding. The number of eggs laid by the fly is the largest from 8 am to 3 pm every day, so the egg collection time should be appropriate. Each batch of fly is eliminated after 15 to 20 days of breeding, killed with hot water or steam, dried and ground into powder for livestock and poultry feed, and then replaced with a new batch.

There are two ways to produce fly maggots and pupate them as new fly species: one is to let them pupate naturally and wash out the pupae with water; the other is to take out the maggots when they turn yellow after about 5 to 6 days of breeding to promote pupation.

3. Cultivation of fly maggots

Fly maggots can be raised in a maggot breeding pond with a brick side height of 20 cm and an area of ​​1 to 3 square meters, or in a bamboo and wood frame with a plastic tray. A plastic tray with a diameter of 50 cm can breed 1.5 kg of maggots, which only requires 3 kg of wheat bran. After 3 to 4 days of breeding, they can be collected and used. The sources of maggot breeding feed are relatively wide, and the costs of different maggot feeds are different, so you can choose reasonably. Wheat bran has a higher nutritional content and a slightly higher price. It is generally used to breed fly species. Cheap wine troughs, bean dregs, etc. can be used as commercial maggot feed.

If wheat bran is used as maggot feed, generally 1 kg of wheat bran can produce 0.5 kg of fly maggots. When using, it is necessary to add water and shake it evenly. The dryness and wetness should be such that water comes out when squeezed by hand and it falls apart when touched (water content 60%~65%). If semi-dry and wet feed such as wine dregs and bean dregs is used, it can be cultured without adding water. The specific operation method of raising maggots is to pour the eggs and wheat bran into a plate, add wine dregs, bean dregs or wheat bran and other maggot feed, and stir it evenly.

Note that the fly eggs should not be exposed on the surface of the maggot feed to avoid water loss and loss of vitality. The thickness of the maggot feed is based on the fermentation temperature in the maggot feed not higher than 40℃ and not lower than 20℃, generally 5~10 cm. In summer, when the temperature is high, the maggot feed should be appropriately thinner, while in winter, when the temperature is low, the maggot feed can be appropriately thicker. Human and animal feces need to be killed for bacteria and parasites before use. The ratio of feed to maggots is generally 3.5~4.0 kg to produce 0.5 kg of fresh maggots, taking chicken manure as an example. Regardless of which raw material is used to raise maggots, the humidity of the maggot feed should be controlled at 60%~65%.

4. Collection of fly maggots

By taking advantage of the fact that maggots are afraid of light, they are collected by scraping the surface of the drinking water in the maggot breeding pool with a dung shovel. The maggots will then drill into the pool and remove the dung on the surface. This method is repeated many times, and only a small amount of dung and maggots will remain. The separated maggots can be directly used to feed livestock and poultry after washing, and then dried at 200-250℃ for 15-20 minutes for processing and storage for future use.

When raising chickens with fly maggots, you can directly choose local chicken breeds, which generally have strong resistance to adversity and disease. Whether they are raised in a shed or raised in an orchard or field, they can achieve a higher survival rate. When choosing chicks, you should choose male chicks with a black body or other colors according to market demand, so as to ensure better sales and prices.

After the maggots are taken out from the maggot pupae, they can be rinsed with clean water and fed directly to chickens. The amount can account for 30% of the total feed. If the maggots are killed by boiling water and then fed to the chickens, the amount can account for 40%. Because the protein content in maggots is high, other feeds should be mainly energy feeds such as corn flour and wheat bran, and there is no need to add soybean meal and fish meal protein feeds.

When raising chickens with fly maggots, pay attention to the following points:

1. The total amount should be 20% of the feed, and should not exceed 30%. If you feed too much, the chickens will eat maggots and then eat them again. The most terrible thing is that it may cause the egg white to crack and the chicken's abdomen to swell and accumulate water, leading to sudden death.

2. It is not suitable to feed young chickens with immature maggots. It is not the common saying that "small maggots are fed to young chickens, and big maggots are fed to big chickens". This is because the small maggots have undigested bacteria in their stomachs and on their bodies. Mature maggots no longer eat, and there are no black threads in their stomachs. The dirt on the bodies of mature maggots that crawl out has also been wiped clean.
