Although the first mammalian embryo transfers were done more than 100 years ago, commercial bovine embryo transfer came into being in the early 1970s with the importation of European breeds of cattle into North America. Since that time commercial bovine embryo transfer has grown throughout the worl...
Embryo transfer technology is globally recognized as the fastest method of genetic improvement in cattle. The process improves cattle reproduction through the insertion of in-vitro fertilized embryos into the uterus of a selected recipient cow with the aim to induce pregnancy. Ronil Prasad, Fiji's M...
