Plasma LH levels were examined at 1 1/2-hr intervals in ram lambs of the Finnish Landrace, Border Leicester and Cheviot breeds on three occasions at 3-week intervals by radioimmunoassay. On each occasion, the mean plasma LH concentration was found to be significantly higher in the Finnish Landrace than the other two breeds, although big variations occurred between individual samples in the same animal. This form of hormonal pulsatile release was most marked in the Finnish Landrace lambs. Testis growth was also measured and was found to be correlated, independently of body weight, with LH concentration on the final sampling occasion.
通过放射免疫分析法，每隔1.5小时对芬兰长白、边境莱斯特和切维厄特品种的雄性羔羊血浆促黄体生成素（LH）水平进行检测，共检测三次，每次间隔3周。每次检测时，发现芬兰长白品种的平均血浆LH浓度显著高于其他两个品种，尽管同一动物的个体样本之间存在很大差异。这种激素脉冲式释放形式在芬兰长白羔羊中最为明显。同时还测量了睾丸生长情况，发现其与最终采样时的LH浓度相关，且与体重无关。
