	abstract = {Groups of 10 Friesian bull calves averaging 142 kg were offered  Winfred forage brassica (62\% leaf) at allowances of 3, 6, 9, 12 or 15\% of  bodyweight (BW) for 6 weeks. Similarly, groups of 8 Friesian bull calves  averaging 150 kg were offered Wairoa forage brassica (67\% leaf) at  allowances of 3, 5, 7, 9 and 12 \% of bodyweight. Calves were weighted  weekly and offered fresh allowances each week. The two experiments were  conducted between January and March of the same year but were not run  concurrently.   There was a significant effect (P<0.01) of allowance on liveweight gain for  calves offered Winfred, with calves on the lowest allowance (3\% of BW)  growing at 0.90 kg/day, compared to 1.20 kg/day for calves grazing the other  four allowances. Calves grazing the low allowance (3\% of BW) utilised  77\% of the total crop, but only 43\% of the stem. On the other hand, calves  grazing the low allowance of Wairoa utilised 90\% of the total crop and 72\%  of the stem without suffering a liveweight penalty. There was no effect of  allowance of Wairoa on calf growth rate and overall, calves on Wairoa grew  at an average of 1.03 kg/day. Choice of a leafy type of brassica maybe  important if the objective is a high degree of utilisation coupled with good  animal performance. Alternatively, on },
