ryegrass staggers
ruminants and horses grazing pastures dominated by L. perenne (perennial ryegrass) may be affected with a severe incoordination which appears with forced exercise but disappears if the animals are left to their own devices. Caused by tremorgen lolitrems from the endophyte Neotyphodium (Acremonium) lolii which infests the grass.

Thus, despite of leaf production being relatively constant from 15 to 25cm, it seems that sward heights targets around 20cm in annual ryegrass would be a compromise between high leaf production with high herbage intake rates, since on using higher pre-grazing heights the remaining stubble after grazing would present a great amount of stems that will become progressively larger in subsequent regrowth, which could lead to a deterioration in sward structure with negative impact for herbage intake and production.
