Problems solved by technology

[0002] The hatching effect of duck eggs is an important indicator to measure the production performance of duck farms, which directly affects the production efficiency of duck farms. The hatching effect is closely related to the preservation method of breeding eggs. Improper preservation methods, even for a short period of time Preservation will greatly reduce the hatching rate of low-breed duck eggs. As the storage time prolongs, the water in the eggs will evaporate, causing embryo aging, changes in nutrients and the reproduction of residual bacteria, thereby endangering the embryos and reducing the hatching rate. Duck eggs often cannot be hatched in time; therefore, inventing a preservation method to improve the hatching rate of duck eggs can effectively improve the economic benefits of duck farms and promote the development of duck breeding field

Abstract

The invention belongs to the technical field of duck egg preservation and particularly discloses a high-hatchability preservation method for a hatching duck egg. The specific method comprises the following steps of (1) treatment of the hatching egg before preservation; and (2) sealed preservation of the hatching egg and treatment during a preservation period. The preservation time of the hatching duck egg can be effectively prolonged and the hatchability and the healthy rate are improved; the hatching egg is soaked by using a urea water solution before preservation, so that harmful bacteria and microorganisms of the hatching duck egg can be effectively killed and lesion of the hatching egg is inhibited; the hatching duck egg is buried and stored by using nutrient soil and air holes in the surface of an egg shell are effectively sealed, so that pollution of external microorganisms can be prevented, moisture evaporation and carbon dioxide loss in the egg can be reduced, gradual dilution of thick albumen, frenum damage and protective film damage on the outer surface of the egg shell are effectively prevented and quality change of the egg is delayed. Chitosan oligosaccharide water solution soaking and ultrasonic treatment are carried out during the preservation period, so that adhesion of an embryo and a shell membrane is effectively prevented, good elasticity of a yolk membrane is kept, the viability of the embryo is effectively ensured and good development of the embryo is promoted.
