Results are the mean of 6 replicates per treatment.
Means within the same column with no common script differ significantly (p < 0.05).
Large yellow follicles (> 10 mm diameter); small yellow follicles (5 to 10 mm diameter); large white follicles (3 to 5 mm diameter); SEM, standard error of the mean.
