Project title: Study on the intergenerational and transgenerational phenotypic and epigenetic effect of in ovo chicken embryo stimulation.

Hypotheses and objectives of the project

The term “epigenetic modifications” refers to phenotypic changes in an individual caused by mechanisms that are not related to alterations in the DNA sequence. These modifications can result from extracellular signals and environmental factors. The in ovo injection of bioactive substances (e.g., probiotics, prebiotics, or synbiotics) can stimulate not only the host immune system through the gut microbiome modification but also fine-tune the gene expression at early stages of development and turn animal more efficient or resistant later. However, it is not clear whether and how these phenotypic changes are inherited in subsequent generations. Therefore, the two leading hypotheses were stated in this project: 1/ Bioactive substances, synbiotic and choline, administered in ovo can stimulate embryonic development and produce a life-long impact on the chicken phenotype (such as gut health, immune system, performance, mortality, and physiological traits); 2/ Epigenetic changes that were acquired in one generation, as a result of the in ovo impact on embryonic and long-term postembryonic development, can be permanently inherited and propagated in future generations. Consequently, the objectives of the project are to analyse whether epigenetic changes that were acquired in one generation can be stably inherited in future generations and to investigate the physiological relevance of this inheritance in intergenerational and transgenerational level. Moreover, the molecular mechanisms behind this type of information transfer will be examined by using a high-informative multi-omics approach. We believe that the results of this project will provide new evidence for offspring programming by in ovo delivery of a synbiotic and choline.

Requirements:
