Temperature is the key to the success or failure of brooding ducks. Due to the poor cold-proof ability of the ducklings after hatching, a slightly higher temperature environment is needed at the beginning of the brooding to ensure the normal growth and development of the ducklings. The temperature of ducklings should be stable between 26 and 28°C after the hatching, so artificial temperature must be given. Then, depending on the growth of the duckling, it is reduced by 1~2°C per day. Now we introduce the artificial feeding of ducklings to temperature 3 methods. Localities can make full use of local resources and adopt relatively simple and energy-saving heating methods according to local conditions. Electric heating umbrella heating method Made of metal or plywood, the upper part is small, about 30 centimeters in diameter, the lower part is big, the diameter is about 100 centimeters, and the height is about 70 centimeters. It is best to have a sandwich to facilitate insulation. A circle of electric heating wire is installed around the lower part of the umbrella and is connected with the power switch. The four corners of the umbrella are used for the post and the lowermost edge is left with a gap of 10 cm to facilitate the ducklings to enter and leave freely. This kind of insulation umbrella can raise 200-300 ducklings at a time. Infrared bulb warming Infrared light bulbs are installed in the brooding room to utilize infrared light bulbs with large heat to achieve indoor warming. The general infrared light bulb is about 40 centimeters from the ground. According to the indoor temperature level to determine the number of installed infrared light bulbs. The advantages of the above two methods are convenient management, stable insulation, clean interior, dry environment, and good brooding effect. The disadvantages are large power consumption and high brooding costs. Common coal furnace heating method According to the structure of a common coal stove, a relatively large special coal stove is made with an oil drum or iron plate, and an air inlet for controlling the air volume is provided, and there is a metal flue leading to the outside. When the coal stove burns and the interior temperature reaches the set temperature, the indoor temperature can be maintained by closing the air inlet. When the temperature is not enough, properly open the air inlet. This is a more economical method of heating.
