中文摘要：

羔羊白肌病又称肌肉营养不良症,是由饲料中微量元素硒和维生素E缺乏或不足而引起的疾病,以骨骼肌﹑心肌和肝脏组织病变﹑坏死为特征。乌骨羊体内的乌骨主要是由黑色素形成,硒元素又是合成黑色素不可缺少的元素之一。由于我国大面积国土缺硒,加上养殖户日常生产管理不善,不在饲料中添加硒,极易引发白肌病。笔者对咸宁市某乌骨羊场病羊通过临床症状、剖检病变、血硒检测确诊为乌骨羊羔羊白肌病,并对预防、治疗和发病原因进行了讨论。在缺硒地区养殖场一定要注重硒元素在饲料中的添加。

英文摘要：

White muscle disease of Iambs, also known as muscular dystrophy, is a disease caused by the deficiency of trace element selenium and vitamin E in the feed. It is characterized by the lesions and necrosis of skeletal muscle, cardiac muscle and liver tissue. Black bones in black - bones sheep are mainly formed by melanin, while selenium is one of the indispensable elements in the synthesis of melanin. It is very easy to trigger white muscle due to the lack of selenium in a large area of land in China, coupled with without adding selenium in the feed due to the poor management in daily production by farmers. The author diagnoses a white muscle disease of black - boned sheep in sick sheep from a certain black - boned sheep farm in Xianning city through clinical symptoms and gross lesion and detection of blood selenium, and discusses the prevention, treatment and the cause of the disease. The sheep breeding farms in the regions of selenium deficiency must pay attention to the addition of selenium in the feed.
