LYF: number of normal large yellow follicles (>10 mm diameter); SYF: number of small yellow follicles (5–10 mm diameter); LWF: number of large white follicles (3–5 mm diameter). Values are presented as least square mean ± SE. a–b means within the same column for each parameter with different superscripts are statistically different at p < 0.05 (Two-way ANOVA, Tukey post-hoc test).
