Title: BIRDS, METHOD FOR PRODUCING BIRDS, AND BIRD EGGS
Abstract:
These birds lay eggs which do not include in the genome thereof foreign genes which have been artificially introduced, and in which the content of ovomucoid has been reduced from that of a wild type. This method for producing birds includes: a modification step for modifying the ovomucoid genetic locus of pluripotent stem cells of birds by cutting with a programmable endonuclease, and a transplanting step for transplanting the pluripotent stem cells, the ovomucoid genetic locus of which has been modified, in a bird embryo. The bird eggs do not include in the genome thereof foreign genes which have been artificially introduced, and have an ovomucoid content which has been reduced from that of a wild type.
