	abstract = {The fleeces of 30,000 ewe hoggets from 12 Merino flocks were   sampled and the mean fibre diameter and clean fleece weight were   measured in 1987 and 1988 and the best were selected to establish a   superfine joint venture (SFJV) flock of 307 breeding ewes. The breeding   objective is to achieve mean fibre diameter below 17um in the adult   fleece while maintaining fleece weight and live weight. Concomitantly,   a random control flock (RC) of 101 ewes was constituted from the flocks   screened. Both flocks are farmed on MAF Technology{\textquoteright}s high country   station at Tara Hills, Omarama.     The screened SFJV flock has significantly lower live weight (p<0.01),   greasy fleece weight (p0.05), loose wool bulk (p<0.001) and mean fibre   diameter by 2 um (p<0.001). Staple length (P<0.001), staple crimp   (P<0.05) and yield (P<0.05) were significantly higher for the SFJV flock   compared with the RC flock. Wool returns of SFJV flock were $81.78/hd   and $107/hd vs $62.21/hd and $47.00/hd for RC flock in 1988 and 1989   shearing respectively    },
