Summary
Abstract Background Recently, there has been increasing interest in the use of multispecies (MS) swards in dairy grazing systems. Methods A plot grazing study was established to investigate the potential contribution of different sward species (perennial ryegrass, legumes and herbs) sown in grazing pastures. Ten sward mixtures were sown, ranging in complexity from a perennial ryegrass (PRG) monoculture to binary mixtures including either forage legumes or herbs to a five‐species mixture; four different nitrogen (N) application rates of 0, 100, 150 and 200 kg N ha −1 were applied to each sward. Results Species abundance for all sward species components was associated with the interaction of time point and sward mixture; species abundance for all sward components, except PRG, was associated
