	abstract = {Data from 1048 young Angora goats by 15 sires in the Department of Lands and Survey{\textquoteright}s flock at Waitangi were used to obtain preliminary estimates of the effects of year, age of dam, sex, rearing rank and birth day (age). Characters studied included weaning weight, 6- and 12- month fleece weight, and yearling fleece weight (the sum of 6- and 12- month weights). Estimates were also obtained of the heritabilities of, and the genetic and phenotypic correlations among, these traits. The weaning weights of kids out of dams aged 3, 4, 5 and 6+ years of age were heavier (P<0.001) than those out of 2-year-old dams by 1.9, 2.2, 2.0 and 2.5 kg respectively. Corresponding differences for 6-month fleece weight of kids were 0.05, 0.05, 0.04 and 0.04 kg (P<0.01) but those for 12-month fleece weight were not significant. Males were heavier at weaning than females (1.6 kg, P<0.001) and also had heavier 6-, 12-month and yearling fleece weights (0.08, 0.10 and 0.18 kg respectively; P<0.001). Single-reared animals had significantly heavier weaning weights and 6-month and yearling fleece weights than multiple- reared animals (2.4, 0.09 and 0.11 kg, respectively). Age was a highly significant source of variation for all traits. The heritabilities of weaning weight, and 6-, 12-month and yearling fleece weights were respectively 0.28, 0.23, 0.40 and 0.53. Genetic correlations between weaning weight and 6-, 12-month and yearling fleece weights were respectively 0.0, 0.38 and 0.24. Corresponding phenotypic correlations were 0.58, 0.28 and 0.44.},
