[Liver function in cows with traumatic inflammation of the reticulum and peritoneum after rumenotomy]

The studies resulted from clinical observations recorded earlier on the basis of which it was found that traumatic inflammation of the reticulum and peritoneum Uzco is accompanied by liver lesion. Basing on the animal material (72 cows) collected in the area of the Station's activity at Busko-Zdrój, the diagnostic value of the selected laboratory liver tests was estimated to be utilized in diagnosing the damage of this organ as well as in the treatment of cows after rumenotomy. The studies showed that for these purposes the determination of total bilirubin and its fraction, the concentration of which in cows of the Uzco breed before the operation exceeded considerably their normal level, is of highest value. In the postoperation period lasting about 10 days, the level of total bilirubin constantly decreased. The determination of total cholesterol and protein was found to be of slightly lower value. Among the opacity tests the iodic one is of highest value in determinations of liver parenchyma lesions in cows with the Uzco. The decrease in the level of total bilirubin and its fraction as well as the decrease in the number of positive reactions to iodic test in the postoperaton period have been recognized as prognostically favourable symptom.
