As much secretion as possible was removed manually twice daily, from both mammary glands of 6 late-pregnant goats beginning on d 137 of gestation. Removing mammary fluid before parturition stimulated fluid secretion by different amounts in individual goats. The mean volume of fluid secreted pre partum by the goats correlated directly with their secretion of triglyceride and the percentage composition of C18 fatty acids in the triglyceride fatty acids; the volume also correlated with the concentration of progestins, but not prostaglandin F2 alpha or oestrone sulphate, in the fluid.
从妊娠第137天开始，每天两次手动尽可能多地清除6只妊娠后期山羊双侧乳腺的分泌物。分娩前清除乳腺液会刺激每只山羊分泌不同量的液体。山羊产前分泌的液体平均体积与其甘油三酯分泌量以及甘油三酯脂肪酸中C18脂肪酸的百分比组成直接相关；该体积还与液体中孕激素的浓度相关，但与前列腺素F2α或硫酸雌酮的浓度无关。
