摘要： 动物性腺激素与其繁殖活动密切相关。为探明斑羚性激素水平的季节性变化，利用放射性免疫分析法，对内蒙古赛罕乌拉自然保护区2015、2016年采集的554份中华斑羚（Naemorhedus griseus）粪便样品和2013年经分子鉴定手段确定性别的雌雄性各20份样品，测定了其中的性激素水平。发现2016年度睾酮水平峰值出现在7月份，为(236.21+23.31)ng/g，但9月睾酮水平与2013年11月差异不显著（P>0.05），维持在一个高水平。孕酮水平峰值出现在5月，为(398.24+39.11 )ng/g，且显著高于其他各月(P<0.05)，雌二醇水平在3月出现峰值，为(36.36+3.18)ng/g，显著高于其他各时间点(P<0.05)，7月水平最低。研究中性激素的季节变化印证了当地文献关于斑羚10月份发情，5月份产仔的记载；同时也表明采集斑羚粪便样品，利用放射性免疫分析法检测其中的性激素含量，分析斑羚性激素季节变化的方法是一种理想的试验方法。

Abstract: The animal sex hormones are closely related to its reproduction activity. To obtain the seasonal variation characteristics of fecal sex hormones level of the Chinese goral (Naemorhedus griseus), we analyzed 554 fecal samples collected in 2015 and 2016 by using radioimmunoassay, while 20 female and 20 male fecal samples collected in 2013 were used as comparison from the Inner Mongolia Saihanwula Nature Reserve. The results showed that testosterone had the highest level in July(236.21 ng/g +23.31 ng/g, Mean+SD). And it also showed a high level in April and had no significantly difference between April 2016 and September 2013 (P>0.05). The progesterone showed the highest level in May (398.24 ng/g+39.11 ng/g) and was significantly higher than in other months (P<0.05). The estradiol levels showed the highest in March (36.36 ng/g+3.18 ng/g) and was also significantly higher than other months (P<0.05), but it showed the lowest level in July. The seasonal variations of sex hormones confirmed the document′s record that the rut season of the Chinese goral is in October and farrowing period is in May, and also confirmed the method of using radio immunoassays to detecte fecal hormones concentration levels of Chinese goral for analysis its seasonal changes is ideal.

Key words: Chinese goral (Naemorhedus griseus), testosterone, progesterone, estradiol
