Method for culturing fertilized sheep eggs with high survival rate for in vitro culture of embryos

摘要

PROBLEM TO BE SOLVED: To provide a method for culturing fertilized sheep eggs having a high survival rate for in vitro culture of a foetation. SOLUTION: The culturing step of an egg mother cell, a semen treatment step, an in vitro fertilization step, and a culturing step of a fertilized egg are included, and a plurality of culture incubators in the step are arranged in an incubator main body and an incubator main body. An individual culture dish, an elevating device that raises and lowers a plurality of culture dishes independently, _{a control device that controls the temperature inside the incubator body and CO 2} and O ₂ , and the incubator body during the process of taking out or feeding the culture dishes. Includes isolation means to isolate. Not only the survival rate of the fertilized egg is improved, but also the culture incubator is provided so that the nutritional condition in the culture incubator can be maintained in the process of constantly observing the fertilized egg.
