1RING = sheeted bottom steel ring feeder; CONE = RING feeder equipped with a cone insert.
2Standard error of least squares means.
3Hay waste measured for two bales during each period over four periods
4DMI = daily dry matter intake, kg/d; DMI, % BW = daily dry matter intake expressed as a percentage of initial mean BW; DOMI = daily digestible organic matter intake, kg/d; DOMI, % of BW = daily digestible organic matter intake expressed as a percentage of BW.
5DM = dry matter digestibility, % of total DM; OM = organic matter digestibility, % of total OM.
