	abstract = {Performance data were collected between October 1985 and October  1991 from a flock of approximately 600 mixed-age Romney ewes allocated  to 3 equal sized age-balanced groups and grazed on the same area at  Whatawhata Research Centre. Two groups were shorn 3 times in 2 years at  approximately 8-monthly intervals. One group was shorn in May, January  and October and the other shorn in January, October and May during each  succeeding 2 year period. The third group were shorn once-yearly in  October.   Eight-monthly shorn ewes weaned heavier lambs and grew more greasy and  clean wool than once-yearly shorn ewes. Shearing treatment did not  affect ewe live weight after shearing in October or any parameter of  lamb production, other than lamb weaning weight. Incidence of casting  was less than 1\%.   Net wool returns from 8-monthly shorn ewes exceeded that of once-yearly  ewes with the associated benefit that shearing 8-monthly as a split  flock system would improve cashflow relative to a once yearly system.  },
