METHOD FOR ACTIVATING OVUM OR CLONE EMBRYO BY ULTRASONIC WAVE AND CREATION OF CLONE ANIMAL FROM CLONE EMBRYO ACTIVATED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for activating an ovum or clone embryo by ultrasonic irradiation, wherein the duty ratio in the ultrasonic irradiation is optimized so as to be suitable for the activation.

SOLUTION: The method for activating an animal ovum or clone embryo by irradiating them with ultrasonic wave for the purpose of embryo development is provided, involving irradiating them with ultrasonic wave with a duty ratio of 10-30%.
