| 中文描述 | 胚胎早期死亡的原因在任何動物都會發生。8-17%的母馬在懷孕早期(< 40天)使用超因波檢查都無法檢查出小馬。大多數的例子中並沒有發現胎兒,可能原因是胎兒被吸收或是流產。就牛而言,懷孕50天後流產比例不高。診斷方式是觀察病史有異常體溫週期或判斷懷孕後又變成沒有懷孕。 |
| 英文描述 | Early fetal loss occurs in any species. About 8-17% of mares diagnosed pregnant by early (<40 day) ultrasound examination do not foal. In most cases a conceptus is never seen and the fetus is considered 'resorbed' or aborted. In cattle the rate of loss flattens out after about 50 days of gestation. Diagnosis supported by history of irregular heat cycles or nonpregancy following confirmation of pregnancy. |
