Abstract

Compared with unsupplemented steers, supplementation with leucaena (0.2 ha head-1), peanut meal (680 g head-1 day -1), or a combination of both, improved the body weight performance of weaner steers grazing native pasture over the post-weaning winter (June–August) and the following autumn (March–May). The mean seasonal weight change over the three winters was –22.5 kg head-1 for unsupplemented animals, + 1.6 kg head for those on leucaena, + 6.4 kg head-1 for those receiving peanut meal and + 122.5 kg head-1 with both supplements. The respective mean seasonal changes over the four autumns were + 4.7, + 27.3, + 15.9 and + 35.9 kg head-1.
There was no compensatory weight gain when the animals grazed green panic pastures over the intervening spring–summer season with a mean gain over three years of 125 kg head-1 season-1.
