	abstract = {The manipulation of ovulation rate in the red deer hind was investigated by administration of steroid-free bovine follicular fluid (bFF). Twenty-four adult hinds, treated with intravaginal progesterone (CIDR), received a daily intramuscular injection of either 0, 4, 7.5 or 11 mls of dextra-charcoal treated bFF (n = 6 per group) on days -1, 0 and +1 from the time of CIDR withdrawal. After CIDR removal, plasma progesterone concentrations declined in all animals. In control hinds, oestrus occurred 2-3 days later and mean plasma progesterone concentrations began to increase thereafter. In bFF-treated hinds, oestrus was delayed by 3-5 days, and plasma progesterone concentrations remained low for at least 7 days after CIDR withdrawal. Plasma LH concentrations were 2-3 fold higher in the bFF- treated groups, relative to the control hinds, for at least 6 days after the end of bFF treatment. Twin ovulations were recorded in 1/6 control and 5/17 treated animals. At pregnancy diagnosis, 10/23 hinds were pregnant having conceived at the treated oestrus (3/6 control and 7/18 treated), but none had more than one foetus. There was no evidence of a dose-response to bFF treatment. These results indicate that in the hind, bFF can be used to manipulate the timing of oestrus and ovulation rate. A component(s) of bFF may thus have the potential to regulate fecundity in deer.},

	abstract = {The effects of Regulin melatonin implants and type G progesterone impregnated controlled internal drug releasers (CIDR) on the early breeding of F+ and ++ Booroola x Perendale and Waihora Romney ewes were compared in a 2 x 2 factorial trial, melatonin v no melatonin x progesterone. The melatonin plus progesterone and melatonin only groups were implanted with melatonin on 12 December and 23 December respectively. While CIDRs were inserted on 7 January and removed on 19 January, when fertile rams were joined with all treatments. Progesterone alone induced oestrus and ovulations 2 to 9 d after ram introduction in 39\%, 50\% and 11\% of F+, ++ and Romney ewes, whereas progesterone plus melatonin induced oestrus and ovulations in 68\%, 76\% and 44\% of the ewes respectively. There was no response to treatment in terms of percentage ewes lambing. The response to treatment in terms of the percentage of lambing ewes with multiples was different in the 3 genotypes. There was no response to either melatonin or progesterone by the F+ ewes, whereas the ++ ewes responded to both additively, leading to a difference of 50\% between melatonin plus progesterone and the control groups. The Romney ewes responded only to melatonin leading to an overall melatonin response of 21\%.},
