	abstract = {This study investigated apparent reproductive failure occurring  in seasonally anoestrous progesterone-primed red deer hinds when they  were induced to ovulate with the GnRH analogue, buserelin. In March  1988 (non-breeding season), each of 11 progesterone-primed red deer  hinds(Groups B and BO) were injected i.m. with 4, 3, 2, 2 and 10 ug  buserelin (Receptal, Hoechst) at -48, -24, 0, 24, and 48 h relative to  the time injected i.m. with 500 ug oestradiol benzoate. During the  breeding season (April), ovulation was synchronised in another 4 hinds  (Group C) using CIDRs. Oestrous behaviour was less noticeable and  delayed (P>0.05) in Group B hinds and peak LH levels were lower (P>0.01)  and occurred later (P>0.01) relative to Group ), BO and C hinds. Two  weeks after CIDR withdrawal 3/5 B, 2/4 O, 3/6 BO and 4/4 C hinds had a  corpus luteum present.  During theses two weeks plasma  progesterone levels were elevated in B, BO and C hinds but were low in  the O hinds. None of the buserelin- and/or oestradiol-induced  ovulations resulted in pregnancy. These results show that ovulations  induced in these anoestrous red deer hinds by the use of a GnRH analogue  or oestradiol were not accompanied by normal hormonal and behavioural  patterns.  },
