通过临床观察、尸体剖检、病理组织学观察和组织化学检查,发现长期饲喂串叶松香草的绵羊可引起肝脏和肾脏发生中度损伤。肝脏的间质中有中度纤维增生,肝细胞发生水泡变性,肾脏可见中度中毒性病变。但是这种损伤并不足以危及动物的正常生长发育。如果在饲喂串叶松香草的同时,再辅以其它的饲料,这种肝肾损伤是可以减轻或消除的。 Through clinical observation, autopsy, histopathological observation and histochemical examination, it was found that long-term feeding of sheep with Cynanchum athrelin can cause moderate damage to the liver and kidney. Liver interstitial fibrosis in moderate, hepatocyte blisters degeneration, renal toxic lesions can be seen moderately. But this damage is not enough to endanger the normal growth and development of animals. If you feed the leaves of Slash grass, supplemented with other feed, this liver and kidney damage can be reduced or eliminated.
