	abstract = {Formononetin is the major red clover phytoestrogen responsible for  reproductive dysfunction in sheep. Formononetin is metabolised in the  rumen to equol which is significantly more oestrogenic. This study was  conducted to characterise the accumulation of conjugated and free equol in  the blood of ewes grazed on either high formononetin (cv Pawera, 0.57\% of  dry matter) or low formononetin (cv G27, 0.25\% of dry matter) red clovers  over a 1, 2 or 3 week period and the subsequent clearance of equol after  removal from the red clover. Seventy mixed age ewes were divided into 7 treatment groups (n=10). Each  group grazed either Pawera or G27 red clover for 3, 2 or 1 week or ryegrass  (control group) prior to mating as one flock on ryegrass pasture. All ewes  were regularly blood sampled. Once mated, the ewes were laparoscoped and  returns to service recorded. Conjugated equol concentrations in both Pawera and G27 ewes increased  over the first 2 days to 23.97 },
