Grayscale intensity of pixels (mean ± SEM) of the trkA immuno-positive area of dominant (black bars) and subordinate ovarian follicles (white bars) collected at the time of ovariectomy (Day-groups; Day 0 = ovulation) in cattle. Intensity values (0 = black; 65536 = white) of the follicular wall (a), the granulosa layer (b), and the theca interna (c). abc Values with no common superscript are different (P < 0.05). *Difference between dominant and subordinate follicles (P < 0.05)
