Abstract

Twenty 8 month old Coopworth wether lambs were continuously grazed for four weeks on perennial ryegrass (Lolium perenne ) infected at two levels with Acremonium lolii endophyte. Lambs were allocated (n=10) to one of high (>95% of plants infected) or low (<5% plants infected) endophyte treatments. Both treatments contained Grasslands cv. Nui perennial ryegrass. Individual feed intake over an 18 day period was determined using the alkane technique. The lambs were also regularly weighed and scored for dags. At the end of the grazing trial serum prolactin, rectal temperature and respiration rate were measured. Ergovaline concentrations in the pasture were also measured. There was no significant difference in liveweight change of lambs f...
