Cryopreserving bovine embryos is a common and successful practice. While freezing technology has improved over the years, it hasn't progressed as rapidly as other reproductive techniques. Vitrification, a method used for human embryos, is not as widely used for bovine embryos. There are different types of freezing machines available, ranging from manual to computer-programmed ones. It's crucial for these machines to cool at the right rate and monitor temperature accurately.
