Popis:	A 3-year farmlet experiment was carried out at Dexcel, Hamilton to evalua te the effects of AR1 (no lolitrem B or ergovaline production) and wild (standard or natural) endophyte-infected ryegrass on milksolids production and cow health. Two farmlets (7 ha each) were managed as self-contained systems with cows rotationally grazing treatment paddocks from September 2000 to May 2003. In the 2000/2001 milking season, cows grazing AR1 endophyteinfected ryegrass produced 10% more milksolids than those grazing wild endophyte-infected ryegrass (247 versus 224 kg/cow, SED = 8.4, P
