CATDOLL : CATDOLL: How to build a duckling insulation shed? Do 12-day-old ducklings need insulation?

1. How to build a thermal insulation shed for ducklings?

The key to building a thermal insulation shed for a duck farm is site selection, because the correct site selection is very important. The duckling brooding shed must be in an open area with good ventilation and good water source. It cannot be set up in a cold and damp corner that is sheltered from the wind. It is difficult to disinfect bacteria and viruses. Sunlight is the best disinfectant. Sun-proof duck sheds and duck farms cannot be separated from ventilation and sunshine. Moreover, ducklings themselves need good light.

2.

The construction of the insulation shed does not need to be luxurious, and a simple shed in the vegetable shed will do. Because duck farming is not a highly profitable industry, it is necessary to increase revenue and reduce expenditure, and adopt methods of saving as much as possible to achieve high efficiency and energy saving. Therefore, in terms of material selection, I recommend simple materials to everyone, which are convenient, cost-saving and effective.

3.

The inside of the site does not need to be hardened, but the outside must be well hardened. However, whether inside or outside the shed, a certain slope must be maintained to facilitate drainage. The insulation shed must be close to the water source to facilitate the ducklings to drink water as quickly as possible. The straight-line distance from the water edge to the shed edge should not be greater than 20 meters. If it is too far, it will be difficult for the ducks to travel back and forth between the shed and the water source. Especially in cold weather, the ducklings may feel that it is too far and too lazy to go, and they will become dehydrated or even die due to not drinking water for a long time.

4.

In terms of electricity, three-phase electricity must be used, because they are all kilowatt lamps, which consume a lot of electricity. If it is single-phase, the line

2. Do 12-day-old ducklings need to be kept warm?

How many days should the ducklings be kept warm after hatching?

1. Insulation days

If the chicks are raised in winter, they usually need to be kept warm for more than 20 days before they can be weaned. However, because the physical fitness of each duck is different, the specific insulation time needs to be determined according to the actual situation.

2. How to keep warm

(1) Usually a hot air furnace can be used to keep the temperature warm. The temperature should be maintained at 30-32℃ for the first three days of brooding. Starting from the fourth day of brooding, the temperature should be lowered by 0.5-1 degree every day to ensure that the indoor temperature is around 20-22℃ at the end of brooding.

(2) The temperature can be judged by the behavior of the ducklings. When the ducklings are close to the heat source and crowded together, curled up and make sharp calls, it means that the temperature is too low. When the ducklings are away from the heat source, their water intake increases and their feed intake decreases, it means that the temperature is too high. When the ducklings can eat and drink normally, are in good spirits, and are evenly distributed in the brooding room, it means that the temperature is appropriate.

(3) Please note that you should not light a stove in the brooding house to keep the ducklings warm, because lighting a stove will increase the concentration of carbon dioxide in the brooding room, resulting in insufficient oxygen, which will affect the growth and development of the ducklings. In addition, it will produce more dust and smoke, which can easily induce respiratory diseases.

3. How big a greenhouse is needed for 2,000 ducklings?

300-400 square meters.

To raise 2,000 ducks, you need about 300-400 square meters of duck shed. If the density of ducks per square meter is too high, it will cause crowding, pile pressure, and accumulated temperature. Duck sheds can be built in places with good sunshine, drainage, and ventilation.

4. How big of a duckling is easier to raise?

It is difficult to raise ducks that are too small. They should be at least ten days to one month old. Adult ducks are easier to raise. Moreover, adult ducks can find food by themselves and are less likely to get sick.

It takes 6 months to raise the ducks. The time to sell the ducks depends on the breed. Meat ducks are usually sold at around 40 days old, weighing 2-3kg when they are released. Mallards (local ducks) usually take 70 days. If they are raised beyond this time, the ducks will eat more but grow more slowly, and will gradually lose money.

5. How to keep the tea extracted in milk tea shops warm in winter?

Usually they are thermos bottles. Especially for making silk stocking milk tea. Once the tea soup is made, it is immediately put into the thermos bottle for insulation. Generally, in a store with high customer flow, the tea soup can be sold out in a short time in the bottle. If the sales volume is not good, let it cool down and then take it out and heat the whole can before taking it back.

I have also seen large tea containers that are shaped like small beer barrels. Those can use heating rods.

Greenhouse insulation

1. Work hard on greenhouse film

First, double film covering. Putting another layer of film under the drip-free film can significantly increase the temperature in the greenhouse.

Secondly, remove dust, dirt and snow on the greenhouse film in time to increase light and raise the temperature in the greenhouse.

Thirdly, cover the plants with mulch. Covering the plants with straw mats or corn stalks at night can increase the temperature by 1℃~2℃. If a thin layer of thatch is added, the temperature can be increased by 2℃~3℃. On this basis, a thin film can be added to reduce water evaporation and avoid heat loss. Also, pay attention to removing the thatch in time to promote photosynthesis of flowers.

2. Start from the surrounding environment of the greenhouse

First, polyester aluminum-coated film can be hung on the north side of the greenhouse to form a reflective curtain, thereby increasing the light in the greenhouse and raising the temperature.

Secondly, digging trenches around the greenhouse and filling them with insulating materials such as horse manure, weeds, and straw can increase the ground temperature.

Finally, lighting smoke fires around the greenhouse can prevent heat outside the greenhouse from radiating into the sky and reduce heat loss.

3. Manage the interior of the greenhouse

First, increase the ground temperature. Generally speaking, if it is cultivated on high ridges, cover the ground with film; if it is cultivated on flat ridges, set up a small arch shed. You can also dig a pool every few meters in the center of the greenhouse, and lay a plastic film on the bottom of the pool. After filling the pool with clean water, seal it with a transparent film. This will allow the water to absorb heat at high temperatures at noon and release the heat for heating at night.

Secondly, heating can be used to increase temperature. You can add a stove or turn on the heating in the shed, but you must install a chimney to exhaust the gas outside the shed in time to prevent gas poisoning of the flowers. At the same time, you cannot burn firewood in the shed because the smoke will damage the flowers.

Secondly, add fertilizer. When organic fertilizer decomposes, it can not only provide nutrients for flowers and enhance their ability to resist freezing, but also release heat. Therefore, horse manure, chopped grass and other fertilizers can be applied in the greenhouse. In addition, wood ash is gray-black and has a strong ability to absorb heat, so it can be spread on the greenhouse floor in appropriate amounts.

7. How long does tin foil keep warm in winter?

In winter, it is still okay to keep it warm for an hour and a half. Even if you have an insulated bag, it is recommended to take it home early and store it in the freezer (below -18°C) to avoid thawing and then freezing it again. When you eat it, there will be ice crystals, and the taste will not be delicate and melt in the mouth. Generally, it can keep warm for about 1-2 hours. Heat preservation is generally used for keeping warm food, lunch, restaurant delivery, etc.

8. Winter antifreeze and insulation plan?

1. Use insulation materials to keep warm, that is, use insulation materials to wrap the parts of the instruments that are easy to freeze or afraid of freezing. When winter comes, check and drain frequently to prevent packaging.

.2. Heating measures Steam heating measures: use pipe steam heating to keep warm. It is best to have steam running 24 hours a day, not too hot,

.3. Insulation protection box measures: The insulation and sealing effect of the protection box should be good to isolate cold air

9. How long do trees keep warm in winter?

You can start cold-proof and heat-insulating work from the end of October to mid-to-late November every year.

For the northern region, it will start at the end of October, which is a bit earlier than the southern region, which will start preparations in mid-November.

10. How to keep grass carp warm in winter?

1. Prepare some necessary equipment, including thermometers (two are recommended to avoid errors), air pumps, heating rods (low power to prevent large-scale freezing caused by prolonged sub-zero temperatures), etc.

2. Take appropriate anti-freeze measures (foam boards, etc.) to prevent sudden temperature drops from causing large-scale freezing of the water and frostbite the goldfish. Also pay attention to the thickness of the ice on the water surface. If the ice is severe, clean it up in time.

3. When raising fish in winter, it is necessary to properly raise the water level to avoid deepening the ice thickness on the water surface due to insufficient anti-freeze measures, and at the same time slow down the rate of temperature change.

4. Try to move the water as little as possible when you are not sure. When moving the water in winter, you need to pay attention to avoid changing the water in the entire tank as much as possible. A stable water body is a condition for fish to spend a good winter. At the same time, it should be noted that moving the water less does not mean not changing the water, but just prolonging the water change time. You can change part of the water every ten days or half a month, and pay attention to the temperature difference when changing the water. At this time, it is easy for goldfish to catch a cold or even have their scales fry if you are not careful. After changing the water, you can use chlorine dioxide to disinfect the entire tank. Appropriate water changes and proper disinfection will help reduce the risk of fish disease outbreaks in spring.

5. Reduce or even stop feeding. Low temperature has a significant impact on the goldfish's feeding appetite. At the same time, the goldfish's digestive ability is also greatly reduced, so it is necessary to reduce the amount of food or stop feeding. Many friends have asked at what temperature to stop feeding. This is different for each person's breeding experience. Generally, the amount of food is reduced below 15 degrees and feeding is stopped at around 5 degrees. Some friends stop feeding at around 10 degrees. At this temperature, goldfish are still very active and eat more vigorously.
