[Biochemical and cytological changes in the milk and blood of cows with subclinical mastitis].
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.
