In five untreated goats, mammary extraction of plasma triglycerides increased at parturition. In five goats that had as much secretion as possible regularly removed from one mammary gland beginning on d 143 of gestation, the change of triglyceride extraction occurred several d before parturition in the emptied gland but at parturition in the contralateral control gland. The experimentally induced early increase of extraction of plasma triglycerides preceded the increase of prostaglandin F alpha concentration in mammary secretion at parturition, and occurred despite abnormally high concentrations of progesterone in the secretion.
在五只未经处理的山羊中，分娩时乳腺对血浆甘油三酯的摄取增加。在五只山羊中，从妊娠第143天开始定期尽可能多地从一个乳腺中清除分泌物，排空腺体中甘油三酯摄取的变化在分娩前几天发生，而对侧对照腺体则在分娩时发生。实验诱导的血浆甘油三酯摄取的早期增加先于分娩时乳腺分泌物中前列腺素Fα浓度的增加，并且尽管分泌物中孕酮浓度异常高，但仍会发生。
