Interaction between transgenerational genetics and epigenetics: Study the cumulative effect of epigenetic variation in poultry breeding selection, explore whether certain epigenetic markers can serve as auxiliary breeding indicators, and how epigenetic interacts with gene mutations to influence traits. Environmental-Epigenetic Interaction Research: Systematically evaluate the changes in epigenetic markers of ducks under different environmental conditions, find beneficial variants and try to solidify these variants to improve breeds. To achieve the above goals, scientific research institutions, breeding enterprises and breeding units should strengthen cooperation. At the basic research level, a duck epigenetic research alliance can be established to share duck genomic resources and epigenetic data, strengthen communication with researchers of model species such as chickens, and learn from research experience. At the application level, industrial experimental cooperation can be carried out, such as the company provides experimental scenarios for different feeding conditions, and scientific researchers conduct biological sample collection and epigenetic analysis to screen out best practice plans. Only through the combination of industry, academia and research can laboratory discoveries be converted into productivity in the farm faster.
