Abstract

Recently there has been renewed interest in the possible impact on animal health and performance and insect resistance of ergovaline in perennial ryegrass (Lolium perenne) naturally infected with Neotyphodium lolii. In an earlier limited study of vegetative plants, ergovaline was found to be concentrated in basal tissues (Davies et al., 1993). We have now examined the ergovaline content of tissue fractions of vernalized endophyte-infected ryegrass plants in spring, and report our findings to draw attention to the effect of the reproductive status of the ryegrass plant on the exposure of grazing stock to ergovaline in the forage on offer.
