Increasing pasture allowances (about 50, 75, 100, 150 and 200 g
green DM/kg liveweight/d) were offered to groups of between 24 and 60
ewe hoggets of six breeds under either set-stocking, slow rotation or
quick rotation grazing systems for 11 months. Quick rotation wools were
finest with lower loose wool bulk. Liveweight, greasy and clean fleece
weight, mean fibre diameter and degree of yellowness increased linearly
with increasing feed allowance while staple length plateaued at the
higher feeding levels. Estimated relative economic returns were related
to clean fleece weight.
