| 摘 要： | 用低硒地区所产饲料作为基础日粮，以妊娠母猪和初生仔猪为实验猪，通过肉眼观察和组织学变化得知，硒缺乏病病理变化具有规律性。其中初生仔猪的骨骼肌具有全身肌肉群呈弥散性变性变化，主要特点是肌肉苍白呈鱼肉样。哺乳仔猪的骨骼肌，病变出现的肌群广泛，受害面积大，可为某一肌群的全部或某一肌群的某块肌肉出现灰白色条纹状病变。病变出现的范围不同，可能是不同月份的个体与硒的耐受力有关。

| Abstract: | The pathomorphological changes were observed on Selenium deficiency in pregnant sows and their piglets,which were fed with basic daily forage manufactured in selenium deficiency areas. The pathohistological changes showed that the pathomorphological changes of selenium deficiency had regularities. The skeletal muscles on all over the body of newborn piglets showed difuse variation. The obvious characteristics were that the muscles were pale and ichthyosarcodous.In the lactation piglets, the areas of damaged muscles were vary large .The greyish white and streaky changes could be found in a piece of muscle or the muscles all over the body. The pathological changing scopes were various in different ages of individuals. They were relating to endurance of selenium deficiency. |
