采用常规石蜡组织切片和长期数据统计观察分析,对长臀精卵巢发育和周年变化特点以及其繁殖习性进行了探讨。依据精卵巢外形以及组织学特征,将长臀性腺发育分为6个时期,其中Ⅰ期性腺只出现在一龄以内的个体,Ⅱ期性腺将持续一年左右时间,经过Ⅲ期、Ⅳ期约一年的发育,长臀进入Ⅴ期发育至成熟并首次产卵排精。性成熟个体精卵巢发育只有后五期。长臀约3龄达性成熟,繁殖期是4—6月,5月为繁殖高峰期。长臀个体性腺发育不同步,但为一次产卵型。
Using conventional paraffin sections and long-term statistical analysis, the characteristics of ovarian development and annual changes and their breeding habits were discussed. According to the shape and histological features of ovary and ovary, gonadal development was divided into six stages, in which stage Ⅰ gonads only appeared in individuals within one year, stage Ⅱ gonads would last about one year, after stage Ⅲ and Ⅳ About a year of development, long-billed into Ⅴ phase to mature and oviposition for the first time. Sexually mature individuals develop only the last five stages of ovarian development. The long-tailed gynostemma reaches approximately 3-year-old sexual maturity, the breeding season is from April to June, May is the peak breeding season. Long-tailed gazelle individual gonadal development is not synchronized, but for a spawning type.
