Dear Linda:
I don't have a dose for ovaban - but I haven't heard of it working, 
either.
The two drugs that you will ahve the best luck with are Human 
chorionic gonadotrophin (Cystorelin) at 100 IU IM, repeated in 7 days 
if necessary.  Or you can use gonadotropin releasing hormone at 20 
ug, repeated in 1 week if necessary.  Both of these drugs are most 
effective if given 14 days after the onset of estrus.
with kindest regards,
