Meat ducks such as cherry valley ducks, Beijing ducks, muscovy ducks and barbary ducks, etc., due to the special structure of eggs, resulting in low artificial hatching rate, is a major problem in the incubation process. In recent years, the use of bionic incubator thin water thermostat can effectively solve this problem, so that the duck hatching rate and breeding rate of meat duck eggs have been greatly improved. Now the relevant technology is introduced as follows: Bionic incubator thin water thermostat composition: The incubator and hatcher are composed of a circular sandwich thermostat and a concave water thermostat. During the early period of hatching, ducks breed eggs from low temperature, and the duck eggs are hatched in a vertical box, so that the meat duck eggs are evenly distributed. After 17 days of incubation, embryonic eggs gradually increase in temperature, not only requiring stable temperature, but also sufficient oxygen, humidity, and cool eggs. At this time, duck eggs should be transferred from a vertical box to a hatching hatch. By adding hot and cold water to the concave hatching box, the egg temperature can be accurately adjusted within the required range. At the same time, by raising, lowering, thickening, thinning, or opening the cover of the incubator, the problem of oxygen supply, cool eggs, and humidification of the embryonic eggs in the middle and later stages until the hatching is adjusted so that it is in a natural imitation state, not only It can significantly increase the hatching rate of meat ducks and increase the adaptability of ducklings to the natural environment. Temperature and humidity control: 1, pre-incubation, egg preheating at 36-38 degrees Celsius, warm-up 6 hours - 8 hours, of which the early high, medium-term level, late slightly lower, slightly higher hatching period, the temperature are: 1 day - 7 days 38.8 - 39.2 degrees Celsius, 8 days - 19 days 38.5 - 39 degrees Celsius, 20 days - 30 days 38 - 38.6 degrees Celsius, 31 days - 35 days 38.6 - 39.2 degrees Celsius. 2, the principle of control of humidity is two high, the middle level. Cool eggs and water spray: In the early stage of incubation, generally do not cool eggs. According to the above-mentioned Schwenn program, the egg temperature in the middle and later stages can reach 38.8 degrees Celsius. The surface area of ​​the shell is relatively small, the pores are small, and the heat dissipation is slow. Cold eggs range in length from time to time, depending on the circumstances, and continue to hatch when the temperature drops to 35 degrees Celsius. Water spray is the key to improving the hatching rate of duck duck eggs. When the temperature is high, spray cold water; when the temperature is low, use warm water of 35-40 degrees Celsius. Spray once a day, spray the eggs until they are soaked, and let them dry before hatching. Embryo eggs in the repeated cold eggs, water spray and the role of carbon dioxide in the air, the eggshell calcium carbonate into calcium bicarbonate, its nature changed from hard to crisp, ducklings are easy to shell, can reduce the stillborn period of stillbirth . Turning times and angles of eggs: Duck duck eggs are turned once every 8 hours during hatching. The angle should be 180 degrees to ensure the quality of the eggs. With manual or rolling type turning eggs, the upper and lower side hearts can be reasonably adjusted to meet the embryonic egg development requirements, and the hatching effect is very satisfactory.
