Summary

Abstract Background Limited information is available regarding the nutritive value and structural characteristics of multispecies swards when rotationally grazed. Methods Three farmlet types were investigated in terms of their nutritive value: Lolium perenne (LP); L. perenne + Trifolium repens (LP+TR); and a multispecies sward containing grasses, legumes and herbs (MSS). Farmlets were stocked with beef steers (2.5 livestock units ha −1 ), grazed on a 1 ha scale to 6 cm (MSS) and 4 cm (LP and LP+TR) residuals. Results A greater ash concentration was found in MSS than LP (84 vs. 75 g kg −1 DM). Both LP+TR and MSS had higher crude protein and lower neutral detergent fibre concentrations than LP. The relative ranking of water soluble carbohydrate and dry matter (DM) concentration was LP > L
