Distribution, etiology, course and diagnosis specificity of polymorbid internal pathology in cows

Abstract

There is introduced the idea as to polymorbidity of internal pathology in high-producing cows, experimentally and theoretically substantiated its pathogenesis. For the first time in Ukraine there was used complex approaching as to the study of clinical and functional status of high-producing cows in different keeping and feeding systems, there were determined physiological limits of biochemical indexes that are indicative to infringement of rumen digestion, carbohydrates and lipid exchanges, functional condition of liver that are the basis for elaborating informative diagnostic methods. Polymorbid pathology was diagnosed in 32% of cows. For the diagnosis of polymorbid internal pathology in high-producing cows represented by ketosis, hepatodystrophy, rumen hypotony the most informative indexes are determining the ketone body in urine, the level of pH in rumen content, the content of butyric acid, general protein and albumins in blood serum, the results of mercury chloride test, hyperfermentemia of AsAT.
