Data are presented as mean ± SEM, columns with different letters differ significantly (p<0.05). Follicle counts are presented as average number per section containing oocytes across the serially sectioned ovary, for 14 weeks of short photoperiod exposure (SD), or 2, 4, or 8 days post transfer to long photoperiod after 14 weeks of SD exposure (PT Day 2, 4, 8).
