Nonsurgical Embryo Recovery and Transfer in Cattle

Abstract

Embryo transfer is a technique which makes it possible for a cow to produce more than one or two calves per year. The value of embryo transfer in cattle is two-fold. In its practical application, a considerable contribution has already been made in the multiplication of the exotic breeds and the transfer of eggs from the better animals of a herd into the poorer ones. As a research tool, it has contributed significantly toward the understanding of reproductive physiology, particularly in the areas of endocrine relationships during the estrous cycle, ovulation, fertilization and early development of the fertilized egg.
