Abstract
Hereford bullocks 18 months old and with mean liveweight 246 kg were in 8 groups of 5 and 2 of 6. For 8 days they were kept in groups in a yard and given sorghum grain and chaffed Rhodes grass (Chloris gayana) to appetite. For the next 4 days they grazed immature wheat and were offered sorghum grain in troughs to appetite. They were then weighed after starving and with feed and the 2 groups of 6 were killed. Groups 1 to 7 were allowed to graze oats of 82 days' growth at 0.40, 0.40, 0.28, 0.24, 0.20, 0.16 or 0.08 ha/bullock. All except group 1 were given dry-rolled sorghum to appetite. Group 8 were kept in a yard and fed on grain and chaffed grass, gradually changed to grain alone. Bullocks in groups 2, 4, 5 and 8 were killed after 96 days and those in groups 1, 3, 6 and 7 after 104 days. Grain intake tended to increase with increasing stocking rate. Except at low stocking rates, crude protein content and DM availability of oats decreased both with time and with increasing stocking rate. Carcass gain/ha was linearly related to grain intake, and the effective conversion efficiency of the grain as estimated by regression equations was 0.097 kg carcass/kg DM intake. Intake of oats in the trial was not measured
