CATDOLL : CATDOLL: Do 12-day-old ducklings need to be kept warm? How to build a warming shed for ducklings?

1. 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.

2. 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

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. Greenhouse insulation design?

I am from Beijing and I make glass greenhouses. The greenhouse uses hollow glass for good heat insulation, and then adds a layer of electric sunshade net for heat insulation.

5. How to build an insulation room?

1. Make all the bamboo strips the same length, pick out the longer ones as horizontal strips, and use the horizontal strips to tie the bamboo strips in the middle. The distance between the bamboo strips is about 1 meter. After fixing them, tie another set of horizontal strips at a slightly higher position, so that the frame is fixed into a certain shape.

2. Put the top part of the tied frame against the bottom of the previously nailed wooden square, and then fix it with nails. The lower part of the bamboo frame is propped outward, about 1 meter away from the wall. Then tie the horizontal bar to fix it. In this way, the bracket part is basically formed. The rope for tying the frame must be strong enough, after all, the shed must be windproof. It will be used for several months, so the quality must be excellent.

3. Cover the prepared plastic film on the outside of the frame. Nail the top with wooden strips to the wooden strip under the eaves so that there will be no gaps. Press down the bottom of the plastic film with bricks. You can also press it with sand, but the main thing is to leave no gaps to prevent wind from leaking. The plastic film at both ends of the warm shed can be fixed to the wall with wooden strips. After the plastic film is covered, use nails to fix a few ropes on the upper wooden strips, tie a rope between every two bamboo strips, and tie the tail of the rope to the brick. This is used to press down the plastic film to prevent it from being blown up in the wind.

7. What are the requirements for thermal insulation floor design?

To make an insulation layer, fill it with special insulation materials, such as thermal insulation asbestos, foam, and try to make it thicker and fill it tightly.

8. Thermal insulation design of breeding greenhouse?

2. Use the method of greenhouse lighting and heat preservation to reasonably design the geographical location of the breeding greenhouse. It is best to design it according to the principle of "sitting north and facing south". Choose a drip-free film with good light transmittance to increase the light transmittance in the greenhouse, thereby increasing the temperature in the greenhouse. Cover the cold-proof materials in time so that the poultry and livestock can get sun on sunny days.

9. What are the design ideas for the thermos flask?

1. First, use a pen to draw the basic outline of the thermos bottle. The main structure includes: bottle cap, handle, bottle body and button, etc.

2 We use black, gray and white to fill the thermos' lid, handle, button and other basic elements respectively to complete a simple black and white style thermos.

3 Next, we need to color the thermos. First, fill the structural path of the thermos' handle, lid and base with orange.

4 Fill the path of the button in the middle of the thermos bottle with sky blue

5 Next, we fill the main path of the thermos with grass green, and then fill the bottom path of the front button area with dark yellow.

6 In this step, we give the button a black shadow, and then use the mesh tool to give the handle, cover, and bottom edge a yellow gradient effect.

7 Continue to use the grid tool to make a green and white gradient effect for the main body of the thermos bottle. Then copy the entire thermos bottle and fill it with translucent gray. Arrange it to the end, so that the thermos bottle has a gray shadow. Complete the thermos product design
