Context Biserrula (Biserrula pelecinus L.) is a relatively new legume species in Australia that has been shown to maintain higher quality forage late in the season than subterranean clover (Trifolium subterraneum L.). Aim This study investigated the suitability of lucerne (Medicago sativa L.), subterranean clover and biserrula, or a choice of both biserrula and subterranean clover, for finishing White Dorper and White Suffolk × Merino lambs during spring. Methods An experiment was established near Wagga Wagga, NSW, in 2013 in a randomised complete block design with three replicates and four pasture treatments grazed by lambs during late spring and early summer. Liveweight, carcass weight and GR fat depth of White Dorper and White Suffolk × Merino lambs grazing lucerne, subterranean clover, biserrula or a choice of subterranean clover plus biserrula were compared. Key results Lambs grazing lucerne had significantly (P 0.05). Conclusions Provision of a companion species or mixture of species when lambs graze biserrula during late spring to summer appears to offer benefits for lamb growth rate over this period.

澳大利亚南部放牧苜蓿、地下三叶草、双叶草或选择地下三叶草加双叶草的白杜泊和杂交羔羊的体重和胴体特征

背景 Biserrula (Biserrula pelecinus L.) 是澳大利亚的一种相对较新的豆科植物，与地下三叶草 (Trifolium subterraneum L.) 相比，它在季节后期能保持更高质量的草料。目的 本研究调查了苜蓿 (Medicago sativa L.)、地下三叶草和 biserrula，或选择 biserrula 和地下三叶草在春季育肥白杜泊和白萨福克 × 美利奴羊羔的适宜性。方法 2013 年在新南威尔士州沃加沃加附近建立了一项随机完整区组设计试验，在春末和夏初羔羊放牧的三个重复和四个牧场处理。放牧苜蓿、地下三叶草、白杜泊和白萨福克 × 美利奴羔羊的活重、胴体重和 GR 脂肪深度 biserrula 或选择地下三叶草加 biserrula 进行了比较。主要结果 羔羊放牧苜蓿有显着性（P 0.05）。结论 当羔羊在晚春至夏季放牧双塞卢拉时，提供伴侣物种或物种混合物似乎对这段时期的羔羊生长速度有益。
