EFFECT OF ALTERED PHOTOPERIOD ON DELAYED IMPLANTATION AND MOULTING IN ROE DEER
The roe deer, Capreolus capreolus, is the only artiodactyle known to exhibit delayed implantation (Short & Hay, 1966). In Great Britain, mating normally occurs between late July and mid-August and after fertilization development proceeds to the blastocyst stage before growth is arrested (Prell,...
