The rapid growth in deer farming and interests in the conservation of
various deer species have stimulated development of embryo transfer pr
ocedures. The protocols developed are based on those used in sheep and
cattle and generally involve surgical embryo recovery following FSH-i
nduced superovulation. Data are limited, but pregnancy rates of around
3.0 per donor female for red deer, and around 1.5 for fallow deer are
being achieved.
