Offered Papers Theme A: Efficient Production from Grassland
Description
In the southern USA one cannot depend on perennial legume-grass pasture systems to have persistently high nutritive quality. 'Jesup' tall fescue, a cultivar with better persistence in the region than 'Kentucky 31', was re-infected with a non-ergot alkaloid producing strain of the Neotyphodium coenophialum fungal endophtye (MaxQTM) and found to give persistence equal to Jesup with its endemic strain (E+), but without animal toxins (Bouton et al., 2002). 'Durana' white clover (Bouton et al., 2004) was developed from regional ecotypes of Trifolium repens f. hollandicum germplasm and found to improve animal performance in both E+ and endophyte-free (E-) versions of Jesup. This experiment aimed to assess the ability of Jesup MaxQ when inter-planted with Durana white clover to provide persistent, high quality pasture in the southern USA.
