Goats' Embryos Cryopreserved More Effectively Through Vitrification, Boosting Livestock Breeding Potential
The study compared two ways to freeze caprine embryos: traditional freezing and fast freezing called vitrification. They looked at how well the embryos survived and grew after thawing. Embryos frozen with a mix of dimethyl sulfoxide and ethylene glycol had the highest cell survival rate at 73.33%, while those frozen with dimethylformamide and ethylene glycol had a rate of 40.00%. The vitrified embryos also had better cell structure preservation compared to the traditionally frozen ones. When it came to growing back once thawed, the embryos from the faster freezing process had the best re-expansion rate at 47.36%, while the traditional freezing had a rate of 25.00%. In conclusion, caprine embryos freeze better with vitrification than traditional freezing, and the dimethyl sulfoxide and ethylene glycol mix is the most effective for freezing them.
