摘  要:
采用3种不同青贮方法对黄花棘豆进行青贮,并每天按10 g/kg体重剂量给试验羊投服,观察黄花棘豆不同方法青贮后对试验羊的病理组织学影响.结果表明,3种方法青贮黄花棘豆后取得较好效果;试验羊连续投服60 d没有出现中毒症状,仅在试验期间提耳应激时表现为轻度转圈运动;病理组织学观察结果表明,试验羊的肝脏、肾脏、肺脏、小脑、脾脏和心肌等实质性组织均有不同程度的损伤,特别是大脑损伤最为明显,其中黄花棘豆添加酶制剂和"棘防E号"青贮组对试验羊肝脏、肺脏和肾脏的损伤比直接青贮组严重.

摘  要:
Three different silage methods were used to processing Oxytropis ochrocephala,and the experiment was performed by 10 g/kg.BW dose per day,then the histopathological lesions of the different silage Oxytropis ochrocephala to sheep were observed.The results showed that the three methods had better effect after silage.There was no poisoning symptom in the test sheep for 60 days.The histopathological observation results showed that the sheep?s liver,kidney,lung,cerebellum,spleen and myocardia all have different degrees of injury,especially the brain damage is most obvious.After adding enzyme preparation and silage group "Jifang E" in Oxytropis ochrocephala silage,the damages to liver,lungs and kidneys were more serious than direct silage group.
