e4“However, a strong decrease in LWG per sheep with increasing stocking rate was found in 2005 when annual rainfall was less than half of the long-term average, resulting in a similar LWG per hectare across the range of tested stocking rates”
e7“Nevertheless, high GI may negatively affect grassland productivity in the long term and the lack of HM on offer on heavy grazed pastures in dry years will require supplement feeding at the end of the vegetation period or the untimely sale of animals”

Other claims from this paper (10)
- Intervention effect Herbage mass decreased significantly with increasing grazing intensity from GI 1 to GI 6
- Observation Grazing intensity had only minor effects on chemical composition and digestibility of standing herbage
- Observation Digestibility of organic matter, organic matter intake and digestible organic matter intake did not differ between GI treatments
- Observation Live weight gain of sheep was not influenced by grazing intensity across study years
- Intervention effect Live weight gain per hectare increased with increasing grazing intensity, reaching 730 g/d at GI 6 compared with 181 g/d at GI 1
- Observation Live weight gain per hectare was similar across the tested stocking rates in 2005
- Observation Intensive grazing does not reduce growth of individual animals in most years
- Association Alternating use of pastures might mitigate the negative effects of heavy grazing on herbage and animal performance
- Association High grazing intensity may negatively affect grassland productivity in the long term
- Recommendation Heavy grazed pastures in dry years will require supplement feeding or untimely sale of animals
