	abstract = {Three groups of 10 ewes each were treated with Repromap sponges  (MAP), Chronogest sponges (FGA) or Controlled Drug Release devices  (CIDR) for 11 days. At withdrawal the delay time until oestrus, LH  surge and ovulation was measured.   There was no significant difference between the two sponge treatments in  mean delay times although FGA treated ewes tended to be less variable in  their activity.   CIDR treated ewes commenced standing oestrus sooner than MAP and FGA  treated ewes (30h vs 42h and 40h respectively P<0.001). Similarly the  onset of the LH surge (31h vs 46h and 46h P<0.001) and ovulation (59h vs  69h and 71h P<0.001) occurred sooner in the CIDR ewes compared to MAP  and FGA sponges.  },

	abstract = {During 1989, two groups of weaner red deer stags (n=18) grazed   either perennial ryegrass (PRG) or Moata annual ryegrass (ARG) based   pastures from mid-May until the end of November. Within each group,   animals (n=6) were either not immunised or immunised against melatonin   using Freund{\textquoteright}s or Dextran adjuvants. Treatment effects upon winter (W)   and spring (S) LWG, proportion of animals attaining target liveweight   (93kg; 50kg carcass weight by November 30), pasture composition,   voluntary DM intake (VFI), anti-melatonin titres and plasma prolactin   concentrations were determined.     During winter, LWG (165 v 140 g/day; P<0.05) and VFI (1.62 v 1.20 kg   DM/day; P<0.001) were greater for animals grazing ARG than PRG pastures,   resulting in a greater proportion of deer attaining the target slaughter   weight (60 v 41\%). Organic matter digestibility and N content were   higher (P<0.05) for the ARG than PRG pastures during winter. Maximum   anti-melatonin titres of 1:15,215},
