The IFRG meeting 2010 was held in the beautiful city of Tours in France. The topics now reported included the storage and early embryo development; new developments in incubation temperature; and the influence of glucose application to poultry embryos. Two aspects of cryopreservation were considered: primordial germ cells, and in vivo cryopreserved cock semen. The latter was tested to assess its feasibility for use in commercial production or preservation of genetic stocks. With regard to commercial poultry production, the data recorded in one study supported the hypothesis that fertility would be higher and would persist for longer in pens where the birds were able to find a physical refuge from other birds. Other factors affecting the production of turkeys, ducks, pheasants, ostriches, chickens and ducks were discussed, thus fulfilling the meeting's objective of reporting research into the incubation and fertility of all avian species.
