The invention discloses a laminating and horizontally-spreading type
hatching method for swan geese, and relates to the technical field of cultivation. Firstly, square pipes of 4 cm * 6 cm are welded or punched through screws, so that a framework with the height of 1.8 m, the width of 2 m and the length of 4 m is formed; secondly, square pipes of 4 cm * 6 cm are used for encircling the framework from top to bottom at intervals of 50 cm, the framework is welded into four
layers, then each layer of the frame is tiled with a wooden plate, each wooden plate is tiled with a rush
straw mat, small square pipes are welded all around in positions which are 20 cm higher than edges of two
layers below the framework, so that guardrails are formed; manual heating is adopted, so that the indoor temperature is raised to 28-32 DEG C,
hatching eggs fertilized for 18-20 days are transferred onto a horizontally-spreading frame from an
incubator, two
layers of
hatching eggs are placed along the peripheries of two layers above the horizontally-spreading frame, a layer of eggs is placed in the middle, and then the hatching eggs are covered with floss silk quilts or common quilts; cold boiled water spraying and egg airing are performed, particularly, the water is sprayed six times every day, and the hatching eggs are transferred to the lower two layers of the horizontally-spreading frame after the water is prayed continuously for 5-6 days; and the eggs are observed for 1-2 days, water spraying and egg airing is stopped when shells are pecked, the
room temperature is maintained to be in a range from 35 DEG C to 38 DEG C, and the swan geese are waited to be hatched naturally. The method effectively improves the hatchability and saves energy, and compared with the original hatchability, the hatchability is improved to about 90%.
