Hatching method of goose hatching eggs

Abstract

The invention provides a hatching method of goose hatching eggs and belongs to the technical field of poultry hatching. The hatching method includes following steps: (1), selecting goose hatching eggs, and putting the same in a hatching environment after being disinfected for hatching; (2), putting the goose hatching eggs into a hatching box, wherein hatching temperature is 36.8-38.4 DEG C, hatching humidity is 55-70%, the goose hatching eggs are hatched under illumination, and type of light is visible light. In the process of hatching the goose hatching eggs, hatching is performed under illumination, illumination can promote development of embryo muscles and organs and stimulate embryo activity and is conductive to increasing hatching rate and quick development of goose embryos in the process of hatching, and goslings are large in body and healthy. By the hatching method, live embryo hatching rate reaches higher than 90%, which is an increase of 5% when compared with conventional hatching methods, a ratio of gosling weight to egg weight is increased by 4.46% when compared with goslings hatched by conventional methods, and hatching peak time is shortened by 4.39h when compared with the conventional methods.

Description

technical field [0001] The invention belongs to the technical field of poultry hatching, and in particular relates to a hatching method for goose breeding eggs. Background technique [0002] Our country is rich in goose germplasm resources, but the fecundity of geese is generally low, and there are only 30-80 eggs per year. At the same time, the hatching effect of goose eggs is not stable, the hatching rate of live embryos is low and there are many weak seedlings. Resulting in loss of hatchery efficiency. If you look at the results of chicken and duck breeding eggs, the ideal state is that the hatching rate of live embryos is above 90%, the rate of healthy seedlings is high, and the young seedlings are large and healthy. The hatching method of chicken and duck eggs is quite different from that of goose eggs. Using the hatching method of chicken and duck can easily lead to dead embryos and low closing rate in the early and middle stages of hatching of goose eggs. At the end ...

AI Technical Summary

Problems solved by technology

[0005] At present, in commercial hatcheries, the hatching process of poultry breeding eggs is generally carried out under dark conditions. For example, the patent publication number CN106106256 discloses a kind of mechanical hatching method for breeding goose eggs. The aseptic treatment in the process ensures the effect of high hatching success rate, but the method does not involve the change of visible light

In addition, this method is only the hatching result obtained under the experimental conditions. However, after the experimental conditions are placed in a large hatchery, the hatching effect obtained is not ideal, mainly because the effect is unstable.
