We collected velvet tissue from Père David’s deer, sika deer (Cervus nippon) and fallow deer (Dama dama). After extracting steroids from velvet tissue with ether, we analyzed the estrdiol concentrations using radioimmunoassay technique. We found that: (1) estradiol concentrations were significantly different in the velvet tissue of these three cervids (P<0.05) and (2) Père David’s deer stags had the highest velvet tissue estradiol concentrations, 105.29±27.53 pg/g.

We collected urine samples from females in the early morning. We also measured urinary estradiol and progesterone levels using radioimmunoassay. Based on the estradiol concentration during the menstrual cycle, we discovered that the length of the menstrual cycle was 286 33±1 67 days. The length of pregnancy was about 200 days. The level of estradiol after impregnation was significantly different with the level during the same period in the non receptive part of the cycle. Thus we could diagnose early pregnancy in female Sichuan golden monkeys by checking their urinary estradiol level .展开更多
