Other claims from this paper (8)
- Intervention effect Annual net herbage accumulation did not differ significantly between the 20-day and 35-day grazing intervals in any year
- Intervention effect Net herbage accumulation was 4.7% higher for the longer grazing interval in the first 2 years
- Intervention effect Net herbage accumulation was 4.1% lower for the longer grazing interval in the final year of the experiment
- Intervention effect Herbage allowance had no significant effect on net herbage accumulation in any year
- Association The interaction of herbage allowance and grazing interval had no significant effect on net herbage accumulation
- Intervention effect Herbage consumption was greater in 2 years out of three under the 20-day regrowth period than under the 35-day treatment
- Intervention effect Average degree of defoliation was slightly greater with the longer grazing interval (44.0% v. 38.4%)
- Intervention effect Only in 1 year was there a significant difference in live-weight gain between the rotation length treatments
