The study was conducted on two groups of cows of Ukrainian black and white dairy cattle in the stall period of detention. In the control group there were clinically healthy cows. In the experimental group there were cows, which the first two days after calving observed clinical signs of postpartum paresis — reduced body temperature, anorexia, recumbency, lack of reflexes to external stimuli, a pronounced S-shaped curve of the neck, coma.

It was established fatty acid composition of total lipids blood plasma cows with postpartum hypocalcemia. It was found that the blood plasma of cows with clinical signs of postpartum hypocalcemia increases the percentage of saturated fatty acids and reduced — unsaturated fatty acids and increased lipid saturation index compared to their values in the blood plasma of healthy cows 1-2 day after calving. In particular, established a probable increase in saturated fatty acids (myristic, margarine) in total plasma lipids of postpartum cows. At the same time the level of monounsaturated (oleic, nervonovoyi) fatty acids significantly reduced. Among of polyunsaturated fatty acids significantly reduced the content of linoleic and arachidonic and increased content of linolenic, eykozatryyenovoyi, dokozapentayenovoyi and docosahexaenoic in total plasma lipids of sick cows compared to their values in clinically healthy.
