Sward state and ingestive behaviour by Friesian dairy heifers under rotational grazing



Sward state and ingestive behaviour by Friesian dairy heifers under rotational grazing



British Grassland Society Fifth Research Conference, University of Plymouth, Newton Abbot, Devon, UK, 8-10 September 1997: 51-52



12 Friesian heifers were rotationally stocked and grazed uninterrupted spring growths of perennial ryegrass from a sward surface height 21.5 to 10.0 cm (period 1), 20.8 to 9.0 cm (period 2) and 37.6 to 9.5 cm (period 3) over 17, 15 and 21-day periods, respectively. Herbage intake rates in the first hour on the new paddocks were 22.1 and 20.4 g DM/min and towards the end of each grazing period were 9.6 and 9.3 g for periods 2 and 3, respectively.
