【摘要】 1997年 7～ 9月和 1 998年 3～ 7月间 ,在江苏大丰麋鹿保护区共观察到麋鹿的 2 7种繁殖行为 ,雄鹿有 1 7种 ,雌鹿有 1 0种。在 1 998年 3～ 7月间 ,利用放射免疫分析法 ( RIA)测定了麋鹿粪样中的性激素水平 ,包括雄鹿的睾酮 ,雌鹿的孕酮、雌二醇和雌三醇。实验结果表明 :1 .许多繁殖行为的发生频次和持续时间表现出明显的季节变化 ( P<0 .0 5) ,如雄鹿的求偶行为、标记行为和性行为及雌鹿的性行为等在发情期有一个峰值 ,而雌鹿主要育幼行为的峰值出现在刚产仔后的 4月 ;2 .粪样性激素水平也表现出明显的季节变化 ( P<0 .0 5)。雄鹿的粪样睾酮浓度在发情期显著地高于其它月份 ,雌鹿的粪样孕酮在产仔前的 3月份有两个峰值 ,在 6月中旬又有一个峰值 ,粪样雌二醇的两个峰值分别在 3月和 4月 ,雌三醇的最高值也在 4月份 ;3.对繁殖行为与性激素水平的相关分析表明 :雄鹿主要繁殖行为的发生频次与粪样睾酮水平呈显著的正相关 ( P<0 .0 5,P<0 .0 1 ) ,如嗅外阴、嗅尿、尿喷洒、泥浴、吼叫、饰角、角触地面、驱赶、约束雌、下颌压雌、爬胯和交配等 ;雌鹿的繁殖行为与粪样性激素水平的相关不显著。更多还原

【Abstract】 From 1997 to 1998, the seasonal patterns of reproductive behavior of Pere Davids deer were studied in Dafeng, China, and the fecal steroid concentrations were analyzed with the radioimmunoassay method. Seventeen types of male reproductive behavior and nine types of female reproductive behavior were observed. The stags and the hinds, in many reproductive behaviors, shown seasonal overt fluctuations, meanwhile the fecal steroids levels were significant difference among months ( P <0 05). There were statistically significant correlations between some male reproductive behaviors and fecal testosterone concentrations ( P <0 05, P <0 01). For examples: anogenital sniffing, urine sniffing, urine spraying, wallowing, bellowing, antler adorn, horning turf, chasing stags, holding hinds, chin resting, mounting and copulating. Although there were no significant correlations between female reproductive behaviors and fecal estradiol,estriol or progesterone, the fecal estrogens levels were largely related to reproductive and maternal behaviors of hinds. The reproduction activities of Pere Davids deer were regulated by steroids, which coincided with seasonal environmental changes.更多还原
