In 1990, 8 of the surviving HFW sires were backcross mated to their daughters (born in 1987 and 1988). There was no evidence for any of these sires being heterozygous, or for any of the sires involved in the backcross being homozygous, for a major gene which affects either fleece weight or liveweight.},

	abstract = {A case farm study of a once-bred heifer system on hill country  using a spreadsheet simulation model was undertaken. Results of the  feed budge and financial data of the once-bred system were compared with  bull beef, 18 month heifer finishing and traditional breeding cow  policies.   The once-bred heifer system generated a gross margin of $48.26/s.u.  compared with $42.50/s.u. for a traditional breeding cow breeding  system, $31.70/s.u. for the 20 month heifer finishing and $52.80/s.u.  for a bull beef system. The once-bred heifer system produced 314 kg  carcass/ha, the breeding system cow 197 kg carcass/ha, the 20 month  heifer system 354 kg carcass/ha and the bull beef system 433 kg  carcass/ha. The major factor affecting the profitability of the once-  bred heifer system was schedule price. The best match of animal  requirements and pasture growth for the once-bred heifer system was  shown to occur for an October calving. This study suggests that sheep  and beef farmers with traditional beef cattle policies could increase  productivity by adopting a once-bred heifer beef production system.  },
