- Ovulation rate and number ova shed in animals treated with vehicle (Vh) or estradiol valerate (EV) at 10 day old and injected with propranolol (Pro) [10−4 M] [20 μL] into the both ovarian bursas at 60 day of age. The animals were sacrificed at next estrus day. Ovulation rate, ap < 0.05 vs Vh group, bp < 0.05 Vh + Pro or cp < 0.05 vs EV group (Fisher’s test); number ova shed ap < 0.05 vs Vh group (Kruskal-Wallis test)
