The correct Answer is:
To solve the question regarding the stage at which embryo transfer into a surrogate mother is done in the Multiple Ovulation Embryo Transfer (MOET) technique, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding MOET**: - MOET stands for Multiple Ovulation Embryo Transfer. It is a reproductive technology used primarily in advanced cattle breeding. 2. **Process of MOET**: - The process begins with a donor cow that undergoes a superovulation program. This involves administering hormones to the donor cow to stimulate the maturation of multiple follicles. 3. **Egg Production**: - Instead of producing a single egg during a natural heat cycle, the donor cow can produce between 6 to 8 eggs due to the hormonal treatment. 4. **Artificial Insemination**: - After the eggs are matured, the donor cow is artificially inseminated. This is the process where sperm is introduced to fertilize the eggs. 5. **Fertilization and Development**: - Once fertilization occurs, the embryos begin to develop. The embryos are monitored until they reach a specific developmental stage. 6. **Embryo Recovery**: - The fertilized eggs are then recovered non-surgically when they reach the 8 to 32 cell stage. 7. **Embryo Transfer**: - The recovered embryos are then transferred into the uterus of a surrogate mother (surrogate cow) for further development. 8. **Conclusion**: - Therefore, the correct answer to the question is that the embryo transfer into the surrogate mother is done at the 8 to 32 celled stage. ### Final Answer: The embryo transfer into the surrogate mother in MOET is done at the **8 to 32 celled stage**. ---
