	abstract = {The effect of nutritional management of Angora goats on fibre  production and fibre quality was investigated over two years. After  shearing in August, does were fed either maintenance (MPA) or ad  libitum (HPA ryegrass/white clover pasture (approximately 1.0 kg and  >4kg DM/head/day respectively). In October half the does were removed  from each allowance group and introduced into the alternate allowance  group. This was repeated in early February, allowance groups being  balanced for their previous allowance history. Fleece weights were  recorded at shearing in February and August. Fibre diameter,  medullation and kemp levels were measured at shearing in February and  August and also in October and May. Doe live weights were recorded  monthly and when fleece measurements were made. After one year of  measurements, does were completely randomised onto new pasture  allowances and the experiment was repeated.   Nutritional treatments generated liveweight differences between HPA and  MPA does throughout the year (P<0.05). February fleece weights were  similar in both HPA and MPA groups in 1990 (1.73 vs 1.67; s.e.d 0.067 kg  for HPA vs MPA respectively) and in 1991 (1.43 vs 1.41; s.e.d 0.060 kg  for HPA vs MPA respectively) though approximately 25\% lower than in  1990. August fleece weights were similar in 1990 and 1991 but were  approximately 20\% higher in HPA does than in MPA does (1.46 vs 1.26;  s.e.d 0.051 kg for HPA vs MPA respectively in 1990 and 1.49 vs 1.20;  s.e.d 0.040 kg for HPA vs MPA respectively in 1991). Increased August  fleece weight was associated with increased fibre diameter (34.9 vs  32.7; s.e.d 0.52 },
