Superovulation and embryo transfer in Wagyu donors and cross-bred recipients

Embryo Transfer (ET) is a technology applied to accelerate the genetic progress of herds. Research on bovine ET has mainly focused on a few popular breeds, but the extrapolation of those results to less explored breeds might be questionable. The objective of this study was to determine the main factors associated with embryo production in Wagyu embryo donor cows and gestation performance in cross-bred embryo recipients through retrospective data analysis.
