Influence of the Ryegrass Endophyte on Sheep Production in a Cool-Moist Environment
Animal disorders associated with the ryegrass endophyte have been most severe in areas subjected to environmental stress (Fletcher et al., 1990). The use of endophyte-infected seed has increased throughout New Zealand since the early 1980s. Eerens et al. (1997) showed that endophyte has little effect on pasture production and composition in cool-moist environments and the need for it was therefore questioned. Ryegrass staggers and faecal soiling of wool on sheep in cool-moist areas of the South Island of NZ are considered to have increased over time (J.D. Turner, pers. comm.).
