Abstract

Parturition in sheep has been found to be delayed on both endophyte (Neotyphodium lolu) infected ryegrass (Lolium perenne) pastures (Eerens et al., 1994) and endophyte (N. coenophialum) infected tall fescue (Festuca arundinacea) pastures (Bond et al., 1988). In both cases endophyte infection had no impact on birth weights of lambs, which contrasts with observations on horses by Monroe et al. (1988). It was therefore proposed that gestation period in sheep was delayed rather than extended, a proposition which was tested in an experiment reported here.
