Influence of the method of vitrification and developmental stages of embryos on cryopreservation efficiency of in vitro bovine embryos produced in Vietnam

Abstract

The study aimed to evaluate the influence of different vitrification methods and developmental stages of bovine embryos produced in vitro during cryopreservation in Vietnam. In vitro bovine embryos were frozen by two methods: (1) Vitrification by cryotop and (2) Vitrification by microdrop. The percentage of embryos obtained after thawing of method (1) was higher than that of (2) (100 vs 81.01%, p<0.05)...
