| 中文描述 | 凹背病是一種銅缺乏引起的神經症候群。小綿羊有兩種型,新生型和延遲型,兩種都是因為母羊懷孕期缺乏銅所引起。新生型可見大腦形成孔洞。延遲型出現在14-30天時。由組織病理學和檢驗出低銅含量診斷。特徵是dysmyelination。在小山羊,這種疾病出現在生命的前六個月;症狀類似山羊關節炎腦炎;症狀在凹背病是對稱性的。有低肝臟銅含量,但血清含量可能正常;可能會有小紅血球性貧血。有Lofstedt等人以飲食控制的方法預防的例子。 |
| 英文描述 | Swayback is a neurologic syndrome caused by copper deficiencey. In lambs there are two forms, neonatal and delayed, both due to copper deficiency in the ewe during pregnancy. In the neonatal form cavitation of the cerebrum may be present. The delayed form appears at 14-30 days of age. Dx by histopathology and demonstration of low copper levels. Characterized by dysmyelination. In kids this disease occurs in the first 6 months of life; signs mimic those in Caprine Arthritis-Encephalitis; signs are symmetrical in swayback. There are low liver copper levels but serum levels might be normal; there can be microcytic anemia. An example of prevention using dietary manipulation was given by Lofstedt et al. |
