摘  要：
用放射免疫法测定了湖羊和三北羊发情周期外周血液的LH、17β-雌二醇和孕酮的含量。发情的LH峰值:湖羊为126.54±7.71ng/ml,三北羊为123.38±9.6ng/ml(1)>0.05)。发情开始时间距LH峰值在两种羊之间有显著差异(P<0.01)。整个情期湖羊雌二醇含量高于三北羊(P<0.05),湖羊为36.18±1.52pg/ml,三北羊为28.72±1.92pg/ml,两种品种羊在周期1—3天孕酮含量维持低水平,周期的5—13天有一峰值,湖羊为7.92±0.18ng/ml,三北羊为6.10±0.1ng/ml,有极显著性差异(P<0.01)。在第13天孕酮含量开始下降,第16天下降到最低值。

摘  要：
Summary The levels of LH estradiol 17β and progesterone in the peripheral blood of Hu-yang and Chinese Karakul ewes during the estrous cycles have been measured by radioimmunoassay. The results are briefly summarized as follows: The LH peak of the Hu-yang ewes was measured to be 126.54±7.71 ng/ml; while that of the Chinese Karakul ewes, 123.38±9.6ng/ml. The intervals from the onset of oestrus to the LH peak of Hu-yang and Chinese Karakul ewes were significantly different (P<0.01). In all cases, the value of estradiol of the Hu-yang ewes was always higher than that of the Karakul ewes, the former being 36.18±1.52 pg/ml and the latter 28.72±1.92pg/ml. On Days 1-3 of the cycle, the progesterone levels of both breeds maintained at a low level. It reached a peak value from Days 5 to 13, with 7.92±0.18 ng/ml for the Hu-yang ewes and 6.1±0.18 ng/ml for the Chinese Karakul ewes,values of breeds were significantly different (P<0.01) and began to drop on Days 13 and declined to the lowest value on Days 16.
