Changes in swan goose (Anser cygnoides) hatchability due to application of a tridimensional silicon layer on eggshells and vertical egg setting during incubation

Changes in swan goose (Anser cygnoides) hatchability due to application of a tridimensional silicon layer on eggshells and vertical egg setting during incubation. Goose egg incubation technology differs from the procedure used for chickens: eggs are washed before putting into an incubator and set horizontally due to their big size. However, the effects of the washing procedure and egg arrangement in the context of the hatchability and quality of goslings has not yet been extensively researched. The current study revealed that positioning eggs vertically facilitated hatching, and application of a silicon layer reduced hatching time. The results indicate that covering swan goose (Anser cygnoides) eggshells with a tridimensional silicon layer before incubation of wet-cleaned eggs can improve hatchability.
