 G In a comparative grazing study at Newton Rigg College, Penrith, Cumbria, 53% of lambs
 grazing a sward containing Puna II perennial chicory reached the target 38-40kg liveweight
 whilst just 18% of the comparison group (perennial ryegrass and clover) had attained target
 weight (2006-07).

 G In an SAC study to evaluate alternative forage brassicas for lamb finishing, Puna II was
 found to reduce feacal egg counts in grazing lambs (2007-08).
