	abstract = {Host resistance to internal parasites, as measured by faecal egg  count and dagginess was investigated in ram lambs born in the 1981-83  years (approximately generation 3) from the Woodlands selection lines.  Lines were selected for either: number of lambs born, 100 day weight,  hogget fleece weight and a production index in which all three traits  are combined; a fifth line was a randomly selected control. Ram lambs  were drenched with anthelmintic and then exposed to contaminated pasture  for a period of 6-7 weeks and then faecal sampled. Total plasma  protein, albumin and pepsinogen were measured.   The results demonstrated significant variation between selection lines  in faecal egg count, dag score, liveweight gain, wool growth and blood  plasma parameters. Between selection lines, faecal egg count was  positively correlated with liveweight gain (0.95) and wool growth  (0.41). Blood pepsinogen and total blood protein were both negatively  associated with faecal egg count and liveweight gain (correlations of  -0.51 to -0.90).   Using sire variation within selection line (progeny of 65 sires)  produced heritability estimates of 0.13 },
