母羊的繁殖问题几乎完全与牧场的Dwalganup品系的早期亚种ranean三叶草有关。公羊没有表现出临床异常。在母羊的表现是不育，一个maternal难产涉及死亡的足月胎儿，脱垂的子宫倒置，可能会影响未繁殖的母羊。阉割的雄性有时会出现泌乳和第二性器官鳞状上皮化生.一个囊性子宫内膜导致豚鼠在地下三叶草的绿色上生存了几个星期。证据支持在三叶草中存在一种雌激素样物质或一种刺激体内天然雌激素产生的物质。|| 摘要摘要：7P。R.弗雷
A breeding problem in the ewe associated almost ex clusively with pastures of Dwalganup strain of early subter ranean clover is descr. Rams do not show clinical abnormali ties. The manifestations in the ewe are infertility, a mater nal dystoria involving the death of the full term fetus, and prolapse of the inverted uterus which may affect unbred ewes. Castrated [male] [male] sometimes show lactation and squa- mous metaplasia in the secondary sex organs. A cystic endo- metrium results in guinea-pigs subsisting for a period of sev eral weeks on the green subterranean clover. The evidence supports the presence in the clover of an estrogenic-like sub stance or a substance which stimulates natural estrogen pro duction in the body. || ABSTRACT AUTHORS: 7P. R. Frey
