[Several biochemical indices of the serum of cows with abortions of a non-infectious nature].

Studied were some biochemical indices of the blood serum of cows showing abortions of noninfectious etiology. It was found that in such cases thre was a statistically significant drop in the amount of the total lipids of the blood serum, which reached 20 per cent as against pregnant cows and 8.5 per cent as against cows that had already given birth. It is stated that the phospholipid blood serum fracitons of cows that have miscarried show a statistically dependable drop only in the case of lecithine. Cows that have miscarried also show a drop of albumin, gamma-globulins, and the coefficient albumin/globulin. In order to establish all disturbances in pregnancy on a preliminary basis it is suggested to use in clinical practices the indices total lipids, phospholipids, proteins, and the albumin/globulin coefficent.
