	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},
