• The aim of the study is to determine the effect of hematological parameters of cows on the course of labor and the postpartum period in highly productive Holstein cows. For this purpose, one group of cows was formed on the principle of analogue pairs in the amount of 30 animals with a gestation period of 7.5–8.0 months, followed by blood sampling from them using the Monovet system in vacuum test tubescontainers to determine morphological and biochemical parameters. Blood was taken 25–30 days before delivery in the morning 2 hours before feeding. Blood values were studied according to generally accepted methods using certified equipment. Subsequently, depending on the nature of the course of the birth, the animals were divided into two groups. The first group included 24 cows without pathology of the course of labor and the postpartum period, the second group included 16 cows with pathologies of the course of labor and the postpartum period. In the process of research, it was found that in 60.0 % of the cows the birth and the postpartum period passed without pathologies, and in 40.0 % of the birth and postpartum complications were revealed (retention of the placenta, acute postpartum endometritis, uterine subinvolution). A comparative analysis of the blood values of cows 25–30 days before birth the course of the labor process and postpartum period showed that in animals without pathology — compared to the animals with pathologies — the hematological parameters are considerably higher (hemoglobin content by 16.42 g/l, total protein by 10.96 g/l, albumin by 7.7 %, calcium by 0.98 mmol/l, glucose by 0.91 mmol, immunoglobin A by 59.77 mg/M), while the content of beta-globulins is lower by 8.51 % and that of enzyme AcT is lower by 25.94 units/l. A decrease in blood biochemical parameters contributes to the manifestation of the pathology of labor and the postpartum period. The data obtained can be used to develop an algorithm for the prevention of postpartum complications in highly productive cows.
