Fig. 17-4. Effect of E+ fescue and domperidone (1.1, 1.65, or 2.2 mg/kg, PO, SID) treatment on serum progestagen levels in gravid mares. First detectable differences (P < 0.05) from pretreatment levels are indicated by stars. Unless otherwise indicated, data points represent four mares per treatment (dagger indicates number of mares in the endophyte free group). Mares not showing signs of impending parturition 7 d after the calculated date of parturition, as determined by veterinary examination, were relocated to E- pasture (from Redmond, 1994).
