Estimated daily dry matter intake (DMI; kg/cow) of herbage (calculated based on individual cow energy output), supplement fed (mixture of maize silage and lucerne silage or grass silage), and total DMI (herbage + supplement; assuming supplement utilisation of 100%) of dairy cows grazing ryegrass and plantain-based swards in a lower input system (3.5 cow/ha stocking rate and 150 kg nitrogen/ha/year; LIRG + PL), perennial ryegrass–white clover mix sward in a lower input system (3.5 cow/ha and 150 kg nitrogen/ha/year; LIRG), or perennial ryegrass–white clover mix sward in a higher input system (5 cow/ha and 300 kg nitrogen/ha/year; HIRG) collected over two milking years, 2017/18 and 2018/19. Bars indicate LSD for farmlet effect within months.
