Abstract
The article presents the results of a study of coagulation hemostasis in cows under conditions of intensive and extensive production in different physiological periods (dry, fresh and at the peak of lactation). Disorders of coagulation hemostasis have been revealed in productive animals in different physiological periods under both intensive and extensive housekeeping, and a relationship has been established with feeding, keeping and exploitation.
It has been established that the index of activated partial thromboplastin time (APTT) is significantly higher in dry cows with both intensive and extensive management. Prolongation of prothrombin and thrombin time and a decrease in the amount of fibrinogen were noted, which indicates a deficiency of coagulation factors and indicates hypo- or dysfibrinogenemia. For the first time, a conclusion was made about the possibility of using indicators of coagulation hemostasis as an objective assessment of the influence of technological factors in conditions of intensification of production.
