Of dexamethasone (Azium) and 10 mgs. ECP (estradiol cypionate). Oxytocin, give to cows that had not calved by 40 hours after dexamthasone injection, shortened the average interval to calving (15.4 hours if returned to pasture, 16.1 if in confinement compared with 32.6 hours with no oxytocin). Three cows did not respond to treatment. ECP did not reduce retained placentas; 77% of the cows induced to calve retained membranes.BeefCalvingDexamethasoneOxytocinConference paper
