总结：在泌乳早期（4-8天）和晚期（20-22天），每窝分离6小时，血浆PRL水平分别为4 - 8 ± 5.8和45 ± 5.7 ng/ml，AP PRL浓度分别为6.1 ± 0.6和6.3 ± 0.5 μg/mg AP。经过6小时的分离期，哺乳2，30，60，和90分钟导致非常显着的增加，血浆PRL水平在泌乳早期。血浆PRL水平的增加，没有看到在泌乳后期，除了在30分钟的哺乳组。在这两个阶段的哺乳组的AP PRL浓度显着低于nonsuckled组。
Summary Separation of litter for 6 hr resulted in plasma PRL levels of 48 ± 5.8 and 45 ± 5.7 ng per ml and AP PRL concentrations of 6.1 ± 0.6 and 6.3 ± 0.5 μg per mg AP in early (4-8 days) and late (20-22 days) lactation, respectively. After a 6-hr separation period, suckling for 2, 30, 60, and 90 min resulted in highly significant increases in the plasma PRL level in early lactation. Increases in plasma PRL levels were not seen in late lactation except in the 30-min suckled group. In both stages of lactation the AP PRL concentrations in the suckled groups were significantly lower than in the nonsuckled groups.
