摘要: 为了探讨犬卵巢组织结构和生殖周期阶段的相关性,试验对犬不同生殖周期阶段卵巢的外观形态和组织结构进行观察。结果表明,犬卵泡期、黄体期和乏情期卵巢体积分别为812.63、1081.80和446.03 mm3,黄体期高于卵泡期和乏情期(P<0.05),卵泡期高于乏情期(P<0.05);卵泡期、黄体期和乏情期卵巢质量分别为0.89、1.14和0.71 g,卵泡期低于黄体期且高于乏情期,但3者之间不存在显著性差异(P>0.05);卵泡期卵巢中可见较多次级卵泡和少量成熟卵泡,黄体期卵巢中可见部分次级卵泡和闭锁卵泡,并有大量黄体存在,乏情期卵巢中卵泡类型主要以原始卵泡为主。可见,犬卵巢形态及组织结构与所处生殖周期阶段有关。

Abstract: In this study,the appearance and tissue structure of canine ovary in different reproductive stage were observed. The results showed that: the volume of canine ovary from follicular stage,corpus luteum stage and anestrus stage were 812.63 mm3,1081.80 mm3 and 446.03 mm3,corpus luteum stage was significant higher than follicular stage and anestrus stage (P<0.05),follicular stage was significant higher than anestrus stage (P<0.05). The weight of canine ovary from follicular stage,corpus luteum stage and anestrus stage were 0.89 g,1.14 g and 0.71 g,follicular stage was lower than corpus luteum stage,and was higher than anestrus stage,there was no significant difference(P>0.05). In the follicular stage ovary,a great quantity of secondary follicles and a small quantity of mature follicles were seen. In the corpus luteum stage ovary,a small quantity of secondary follicles and atretic follicles were seen,and there were a great quantity of corpus luteums. In the anestrus stage ovary,the main category of follicles were primordial follicle. As above mentioned,the appearance and tissue structure of canine ovary were concerned with reproductive stage.
