Sta., Gayndah, Qld. 4625, Australia. Tropical-Grasslands. 1984, 18: 3, 121-130; 20 ref. Hereford steers grazed during 1971-4 on native pasture consisting of 43% Bothriochloa bladhii, 25% Dichanthium spp., 17% Heteropogon contortus, 7% Chloris divaricata, 2% Aristida spp. and 6% other spp. Supplementation with (a) 0.2 ha leucaena pasture/head, (b) 680 g groundnut meal/head day or (c) a combination of both improved liveweight gain compared with (d) unsupplemented animals. Mean seasonal wt. changes over the 3 winters (June-Aug.) were (a) +1.6 kg, (b) +6.4 kg, (c) +22.5 kg and (d) -22.5 kg/head. Corresponding gains in liveweight over the 4 autumns were 27.3, 15.9, 35.9 and 4.7 kg/head, resp. Supplementation over the winter did not affect subsequent liveweight gains when the animals grazed green panic pastures between Sept. and March. This abstract relates to the following species:
