Clinical And Morphological Characteristics At Combined Pathology Of The Mammary Gland, Endometrium At Cows And Its Influence On The Protein Component Of Milk

Researchers on simultaneous studying of hematological, biochemical and immunological structure of blood of cows, a protein component of milk and histological structure of a mammary gland and an endometrium at cows both with subclinical mastitis, and with the combined course of subclinical mastitis and postpartum endometritis are carried out. It was revealed that the blood parameters had deviations from the physiological norm, and the immune responses of the body were reduced, while there was an increase in the percentage of rod neutrophils, leukocytosis, as well as lymphocytopenia, an increase in the percentage of eosinophils, accompanied by a decrease in albumins, beta-globulins, an increase in alpha - and gamma - globulin fractions, the activity of redox processes decreased, the level of resistance of the body with a violation of homeostasis decreased, indicating the presence of acute inflammatory process in animals body. At the same time, the inflammatory process at cows with combined pathology was more expressed. The histological examination of the mammary gland found that the alveoli were predominantly polymorphic, of difference sizes and contained serous fluid with an abundance of fat and milk inclusions. In some places, the alveolar septum expanded due to loose connective tissue and blood capillaries. Lactocytes were sometimes vacuolated and rejected significantly from the basal membrane of the alveoli. At the same time, with the increase in the number of somatic cells in milk, the content of whey proteins increased, but the number of caseins decreased. Because of the imbalance of essential amino acids and the presence of a limiting amino acid tryptophan protein component of the milk had a low biological value, and with an increase in the concentration of somatic cells in milk it is expressed to a greater extent.
