From day 182 to day 276 of pregnancy, mature Angus cows were offered daily pasture al-
lowances of 6, 12, 18 or 24 kg DM. Birth weights varied with treatment in a curvilinear
manner. Calf growth rate was positively related to birth weight wihin treatments and nega-
tively related between treatments. The interval from calving to oestrus was 1.2 days shor-
ter toeach kilogram increase in pasture allowance before calving. There was little effect of treatments on serum levels of somatomedins in cows or calves. The lower pasture  allo-
wances did not reduce milk intake in the first 3 weeks of suckling.
