%X Uterotrophic responses in ovariectomized ewes when fed or grazed on Mount Barker, Yarloop or Dwalganup varieties of subterranean clover are reported. The high formononetin varieties Dwalganup and Yarloop always elicited a uterotrophic response. The low-formononetin, high-genistein and biochanin A variety, Mount Barker, stimulated a uterotrophic response, using a 5-day bioassay, when fed at 200g/day or 800g/day, but little or no response when grazed. When chopped lucerne hay was offered with 200 g of the Mount Barker the uterotrophic response was suppressed and the mean uterine weight was not significantly different from that of the negative controls (P= 0.57). The uterine weight of sheep eating 200 g/day of Yarloop and offered lucerne chaff or pellets in one experiment was lower (but not significantly lower) than the unsupplemented group. This trend may be worthy of further investigation.
