Theme: Exploration of the function of chicken gut microbiota and mode of action of probiotics by using germ-free environment (Tentative)
Organizer: Atsushi Tajima, Ph.D.
Abstract
Two major approaches are being taken to understand the role and function of chicken gut microbiota. Firstly, with the latest molecular biological techniques, metagenomics can reveal the complex community of microbes in the gut and has great potential to access functional pathways of the gut microbiota. This is an attempt to understand the role of the combined microbial consortia in the gut through detailed analysis of large comprehensive data sets. The advantage of metagenomics is that it allows entire gut microbiota to be studied, including unculturable bacterial species, in the context of extensive microbe:microbe and microbe:host interactions.
Another approach is the effect or function of specified target bacteria could be well observed in germ-free environments by simplifying or controlling bacterial communities colonizing in the gastrointestinal tract. For example, it is possible to observe the direct microbe:host interactions in test bacteria mono-associated animals. In the simplified gut microbiota with a limited number of bacterial species, the interaction of each bacterial species can be observed with less complexity. The speakers have been working on a unique approach to elucidating the mechanisms of action of gut microbiota and probiotics by making mono-associated or simplified microbiota chickens made from ex-germ-free birds. Through this symposium, we would like to introduce findings on intestinal microbiota obtained from those ex-germ-free chickens.

Afternoon Session: 14:00–16:00
Theme: Application of advanced biology to poultry production
Lead Organizer: Hiroshi Kagami, Ph.D.
Co-Organizer: Guojun Sheng, Ph.D.
Abstract
Advancement of poultry science is expected to improve poultry production. For the improve of the chick hatchability, developmental analysis from early embryos to hatching is important. Germline chimera is one of the useful tools for poultry genetic conservation and breeding. To increase poultry meat and egg consumption, scientific analysis on food chemistry is essential. Due to the scientific and industrial importance, this international symposium will invite leading/young scientists in poultry developmental biology, stem cell engineering, reproductive engineering, and food chemistry to present the latest research results. Active discussion will be expected for the advancement of poultry science and industry.
