Some biochemical and cytological investigations were carried out with milk and milk serum, blood and blood serum of 87 cows, of which 57 manifested symptoms of subclinical mastitis and 25 were normal. It was established that the milk of animals having subclinical mastitis had lower content of lactose, inorganic phosphorus, and sialic acids; on the other hand chlorides were at a higher level, and the activity of alkaline phosphatase rose. Besides, the contents of serum albumin and gamma-lactoglobulins showed dependable rise, while those of alpha-lactoglobulin and beta-lactoglobulin dropped. Dependable was likewise the drop of the total protein level. However, no changes were found in the total protein content and the distribution of protein fractions in the blood serum of cows manifesting inflammation of the udder.
对87头奶牛的牛奶和乳清、血液和血清进行了一些生化和细胞学研究，其中57头表现出亚临床乳腺炎症状，25头正常。结果表明，患有亚临床乳腺炎的动物的牛奶中乳糖、无机磷和唾液酸的含量较低；另一方面，氯化物含量较高，碱性磷酸酶活性升高。此外，血清白蛋白和γ-乳球蛋白的含量可靠地升高，而α-乳球蛋白和β-乳球蛋白的含量下降。总蛋白水平也可靠地下降。然而，在表现出乳房炎症的奶牛的血清中，总蛋白含量和蛋白组分分布没有发现变化。
