To recover embryos from the donor
What is an important characteristic of a good donor female?
High milking ability and elite genetic characteristics
What is the purpose of hormonal synchronization in embryo transfer?
To synchronize the hormones of the donor and recipient
What is the role of the recipient female in embryo transfer?

What is the primary goal of superovulation?
To increase the number of viable embryos
What is an embryo?

What is the purpose of superovulation in animal breeding programs?
To increase the number of viable embryos available for collection
What is the definition of superovulation?
The induction of multiple ovulations in a female animal
What is the advantage of superovulation and embryo transfer in animal breeding programs?

This quiz covers the concept of Embryo Transfer (ET) in animal breeding, which involves collecting and transferring embryos from genetically superior females to surrogates. It enhances reproductive efficiency and spreads valuable genetics. Test your knowledge of ET and its applications!
