These characteristics, and mineral status of growing wether CM2) and lowest in lambs fed 2.0% H (12.9 CM2). No compared to the control after 4 h of incubation. The low compared to the control at 12 h. These treatments also compared to the control at 24 h. Rate of digestion was compared to the control.
