The effect of rotating black holes evaporating very early in the universe is considered. They produce oppositely directed neutrino and anitneutrino currents which push matter and antimatter apart. This separation mechanism is too feeble t explain the present baryon to photon ratio of 10/sup -9/, nor will it have other significant observational consequences.
