Spring sown L. angustifolius Uniharvest was grazed by weaner lambs at pre-flowering, flowering, secondary flowering and at the green pod stage. DM on offer rose from 510 g/msuperscript 2 at pre-flowering to 1000 g/msuperscript 2 at the green pod stage. At all stages of plant growth, leaf material was grazed preferentially followed by flowers and pods. Following grazing the lambs left 200-300 g DM/msuperscript 2, the amount increasing as plants matured.
