Hemostatic system - this is an important mechanism for maintaining hemostasis. At the same time, particularly hemostatic system in healthy active lactating cows with mastitis beginning are not completely clarified. The goal - to find out the level of functional activity of hemostasis in cows in mid-lactation in norm and in conditions of incipient mastitis. Investigations were carried out on 61 cow calving 3-4 contained in the conditions of the Samara region. Of these, the control group consisted of 24 healthy cows and 37 cows with signs of incipient mastitis amounted experimental group. The paper applied hematologic and statistical methods. Based on literature data, it is clear that breastfeeding affects the intensity of the hemostatic process. The paper found that in mid-lactation cows healthy there is a weakening of activating effects in hemostasis and increased fibrinolysis mechanisms. This leads to the maintenance of their optimum rheological properties of blood, ensuring delivery of the required amount of nutrients and oxygen to all the organs and tissues, promoting the rise of milk production. In the case of inflammation of the mammary gland in cows come changes in the hemostatic system activities that form the propensity to thrombosis. Developing their hemostatic activation is associated with simultaneous strengthening of its plasma and platelet units. It becomes clear that in lactating cows in the early development of the terms of mastitis occurs strengthen hemostatic mechanisms.
