Induction of maternal behavior was performed in 63-week-old hens of the JV15 (or "Vedette") strain which had previously exhibited brief incubating phases during the preceding egg-laying period to discover if their maternal behavior differed from that induced in hens who had no previous record of incubating. The degree of maternal behavior exhibited showed large variation among individuals. However, hens with a history of one or more spontaneous, brief incubation bouts and hens without such histories showed similar responsiveness toward chicks and similar levels of general activity. In most of the subjects, the establishment of maternal behavior was accompanied by a significant long-term fall in the plasma levels of luteinizing hormone whereas the plasma levels of prolactin appeared to be unaffected.
对63周龄的JV15（或“Vedette”）品系母鸡进行母性行为诱导，这些母鸡在之前的产蛋期曾表现出短暂的抱窝阶段，以探究它们的母性行为是否与之前没有抱窝记录的母鸡所诱导出的母性行为不同。所表现出的母性行为程度在个体间存在很大差异。然而，有过一次或多次自发短暂抱窝行为的母鸡和没有此类经历的母鸡对雏鸡表现出相似的反应能力以及相似的总体活动水平。在大多数实验对象中，母性行为的确立伴随着促黄体生成素血浆水平的显著长期下降，而催乳素的血浆水平似乎未受影响。
