What are the environmental requirements for goose breeding and incubation?

A small-scale goose farm can let the geese hatch naturally, or use a female goose as a surrogate incubator. A large-scale goose farm needs to use artificial incubation, and the incubation period is 31 days. Select fresh breeding eggs of suitable size, normal egg shape, color meeting the breed requirements, and clean surface, disinfect them by formaldehyde fumigation (add 15 grams of potassium permanganate and 30 milliliters of formaldehyde per cubic meter, at room temperature 24℃—27℃), then place them in the incubation room (22℃—24℃) to preheat for 6—8 hours before setting them for incubation.

Temperature: The temperature for geese in the early incubation stage is 38.3℃—39.0℃, in the middle stage 37.5℃—38.0℃, and in the late stage 37.0℃—37.5℃.

Humidity: The relative humidity is 75%—80%.

Egg turning: Turn the eggs once every 2—3 hours, with a turning angle of 90 degrees. When turning the eggs, the movements should be light, steady, and slow, so as to avoid rupturing the blood vessels of the yolk membrane and separating the allantoic chorion from the shell membrane, which would cause embryo death.

Cooling the eggs: In the late incubation stage, cool the eggs 2—3 times a day, with the cooling temperature at 25℃~27℃. If the room temperature is too low, development will be affected due to “flash eggs”.

Candling: During the incubation process, candling must be carried out 2 times, respectively on the 8th day and the 28th day after incubation, to detect infertile eggs and dead-in-shell eggs. After the second candling, transfer the embryos to the hatcher. Hatching begins on the 30th day and ends on the 31st day.
