Mature, non-pregnant, female armadillos (Dasypus novemcinctus) were killed throughout the year (3-6/month, N = 54) and both ovaries were examined for follicular development. All normal and atretic follicles > 358 micrometers were counte. Total number of normal follicles remained constant from January to June but decreased by 50% in the remaining months except in October and November. Follicles > 978 micrometer (those likely to be ovulated) were found during each month but more (> 3/ovary) were present during April, May, June and October. Atretic follicles remained constant (4-6) except in July and August when the number (10-12) was doubled. A single CL was present in 2/4, 6/6, 1/6, 1/3 and 2/3 animals in July, August, October, November and December, respectively. These data confirm that armadillos ovulate in July and suggest that ovulation may also occur in some animals in late October or November.
全年捕杀成熟、未怀孕的雌性犰狳（九带犰狳）（每月3 - 6只，共54只），检查双侧卵巢的卵泡发育情况。对所有直径大于358微米的正常卵泡和闭锁卵泡进行计数。正常卵泡总数在1月至6月保持恒定，但在其余月份（10月和11月除外）减少了50%。每月均发现直径大于978微米的卵泡（可能排卵的卵泡），但在4月、5月、6月和10月数量更多（每个卵巢超过3个）。闭锁卵泡数量保持恒定（4 - 6个），但在7月和8月数量翻倍（10 - 12个）。7月、8月、10月、11月和12月分别有2/4、6/6、1/6、1/3和2/3的动物有单个黄体。这些数据证实犰狳在7月排卵，并表明部分动物可能在10月下旬或11月排卵。
