黄牛过食精料病理学与治疗同步研究

The Synchronous Study on Pathology and Treatment of Overfeeding Cattle with Concentrated Feed

本试验将受试牛分别过食玉米和大豆进行病理学与治疗同步研究。结果表明两组牛瘤胃液和血液ｐＨ值发病前后有明显差异（Ｐ＜０．０５和Ｐ＜０．０１）；两组过食后的变化指标都是酸中毒的典型指征而非碱中毒。鲎试验检测胃液和血液细菌内毒素含量为１．２～４．８ｎｇ／ｍｌ，证实酸中毒中的同时两组都并存革兰氏阴性细菌内毒素血症。在与病理学变化同步治疗时，采取抗酸中毒、抗内毒素血症及解除脱水为主的综合治疗。

The synchronous study on pathology and treatment of overfeeding the experimental cattle respectively with corn and soybean was carried out in this experiment.The results showed that all the changes of the indices in the ruminal fluid and blood of two groups of overfed cattle demonstrated that overfeeding could cause acidosis,not alkalosis,and at the same time the G-bacterial endotoxemia coexisted.The satisfactory curative effect could be obtained mainly by the synthetic treatment of anti acidosis and anti endotoxemia so as to relieve dehydration.
