Duck breeding thermal insulation equipment and utensils

Most of the necessary insulation equipment and utensils for brooding are the same as those used for chicken brooding. All localities can choose to use according to the characteristics of the region.

1. Insulation umbrella, also known as a nanny umbrella, is shaped like a large wooden bucket with a small upper part and a diameter of 8 to 30 centimeters. The lower part is large and has a diameter of 100 to 120 centimeters and a height of 67 to 70 centimeters. The outer shell is made of iron sheet, aluminum alloy or wood board (fibre board), and the interlayer is filled with heat-insulating material such as glass fiber (rock wool). The outer shell can also be made of cloth, and the inner side is coated with a layer of heat insulation material to form a foldable umbrella. . Insulation umbrellas use electric heating wire or far-infrared heating plate for heating (other countries also use gas or liquefied petroleum gas for heating), umbrella tops or umbrellas are equipped with temperature control devices, under the umbrella should also be equipped with lighting and radiation board, Leave 10 to 15 cm clearance at the lower edge of the umbrella to allow ducklings to come and go freely. This kind of heat preservation umbrella can raise 200-300 ducklings each. When the temperature in winter is low, care should be taken to increase the room temperature while using the nanny umbrella.

2. The coal stove adopts a stove-like air intake device, the air inlet is set at the bottom layer, the original air inlet of the coal furnace is blocked, another air inlet pipe is installed, a small piece of glass is added at the top, and the firepower is controlled through the opening of the glass. Adjust the temperature. The upper side of the furnace is equipped with an exhaust pipe, leading to the outside. This method is mostly used to increase the room temperature, when using this method must pay attention to ventilation, to prevent carbon monoxide poisoning.

3. The infrared lamp is heated directly in the room using an infrared light bulb. The commonly used infrared light bulb is 250 watts, can be arranged at equal distances when used, and can also be a set of 3 to 4 infrared light bulbs. At the first week of age, the bulbs were 35 to 45 cm above the ground. As the young age increased, the bulb height was gradually increased. The use of infrared light bulb heating, temperature stability, indoor litter drying, easy management, save manpower. However, the infrared lamp consumes a large amount of electricity, the bulb is easily damaged, the cost is high, and the place where the power supply is not normal should not be used.

4. There are two kinds of smoke tunnels: underground flues (ground dragons) and ground flues (fire dragons). It consists of a stove, a flue, and a chimney. The ground flue is conducive to heat dissipation, and the underground flue can keep the ground flat and easy to manage. The flue shall be built in a brooding room with a stove, fueled with coal or firewood, and a chimney at the other end. The chimney shall be more than 1 metre above the roof, connecting the stove and the chimney through a flue, and introducing the temperature of the stove into the smoke. Road inside. The material used to build the flue is best to use adobe, which is conducive to heat preservation and heat absorption. The fires used in rural areas in northern China are also underground flue-type. In addition to the above methods, methods such as warming the fire, warming the brooding cage, and the like may also be used.
