The wild geese have a later sexual maturity. Generally, the female geese need 3 years to be able to lay eggs. After artificial domesticated geese, the sexual geese can advance to 9 to 10 months of age, and they can have more than one female. Wild geese can be artificially hatched after 2-3 generations of domesticated breeding. When breeding geese enter breeding period, they should provide sufficient water for their mating, and timely collect eggs for artificial hatching. Should pay attention to the following points:

1. Eggs should be fully sterilized and then enter the egg bank. Eggs are often contaminated with grass and feces. Only a small amount of bacteria is present when the eggs are produced. After 30 minutes, the bacteria can enter the inside of the human eggs through the shell holes. The sooner you disinfect the eggs, the better. The specific approach is to first put the eggs into the sterilizer, 28 ml of formalin solution per cubic meter, and 14 g of potassium permanganate to prepare the medicines. When disinfecting, the formalin should be poured into glass or porcelain containers. Inside (due to the large amount of bubbles generated during the reaction, the volume of the container used is 5 to 7 times larger than the volume of formalin used), and then poured in potassium permanganate, close the doors and windows, a few minutes later, the formaldehyde vapor overflow, 12 After 24 hours, open doors and windows, release residual gas, and move the eggs into the egg bank. Solid formaldehyde can also be used for disinfection. The dose used is 35 grams per cubic meter of space. Solid formaldehyde is placed on a heat source when disinfected. Formaldehyde gas can be generated without temperature control. Other requirements are the same as above.

2. Preheat the common egg storage room temperature before hatching between 12-15 degrees Celsius. Preheating the egg before hatching can make the embryo have an adaptation process to the external environment to prevent the egg from sweating. The method is to move the eggs from the egg bank into the hatchery before hatching, disinfect with the immersion method, place in the hatchery for 6-8 hours, and then incubate. The commonly used drugs used in geese soaked eggs are potassium permanganate, poisonous poison, bacteria poisoning and Eddy V. When disinfecting, use warm water to match the drug to the desired concentration according to the instructions. Immerse the eggs in the liquid for 3 to 5 minutes, remove and dry them, and wait for incubation.

3. Maintain proper hatching conditions Dayang's incubation time is generally 28 to 31 days. The condition of hatching will directly affect the incubation period of the eggs. Which temperature is an important factor in determining the length of the incubation period. For the entire batch of hatching eggs, mostly variable temperature hatching, the temperature range of 39 to 37 degrees Celsius; while batch hatching eggs are incubated at a constant temperature of 38 ~ 38.5 degrees Celsius. Another important factor affecting the hatching rate is the humidity. The proper humidity can make the heat of each part of the egg even, and increase the brittleness of the egg shell, which is beneficial to the hatching of the young geese. In general, the principle of controlling humidity in the process of hatching eggs is two middle highs, and the specific temperature and humidity can refer to the following table. In addition, the ventilation during the incubation process is also very important, especially in the middle and late stages of incubation, with the strengthening of the metabolic capacity of the embryo, the oxygen consumption will also increase, under the premise of ensuring the normal temperature and humidity of the incubation, the better the ventilation, the better.
