Abstract. The research aimed to determine the effect of the metabolic composition based on succinic acid with components capable of hastening the metabolic processes of high-yielding cows closer to the maximum norm on metabolism and postpartum pathology during the perinatal period. The work was performed in the Kursk region during the period of mass calving from January to April 2019. For the experiment, we formed two groups of cows (control and experimental) of the Black-and-White breed with obvious symptoms of metabolic disorders. Their age ranged from 4 to 7 years; the level of productivity according to the last completed lactation was 6500–7000 kg; each group included 27 animals at the calving stage. After calving, the cows from the control group were fed molasses dissolved in water 1:5 in the amount of 0.5 L for consecutive 15 days in the morning. The cows from the experimental group were fed 0.5 L of the metabolic composition. During the first hours and in 11 days after the delivery, their blood was taken for biochemical analysis. In the blood of the animals from the experimental group, the content of total protein increased, compared with the control group, by 3.4 g/L; the content of glucose – by 1.45 mol/L; reserve alkalinity – by 5.2% of CO2; at the same time we registered an increase in the content of trace elements and a decrease in the amount of ketone bodies (by 4.02 mg%). In the blood of the animals from the control group, total protein and reserve alkalinity decreased by 3.8 g/L for 11 days; the content of glucose reduced by 0.37 mol/L, which was associated with a violation of protein, carbohydrate, and mineral metabolism, while the number of ketone bodies increased by 2.2 mg%. The effective use of the metabolic composition as a therapeutic and prophylactic agent in the pathology of metabolic processes and postpartum complications during the perinatal period of high-yielding cows confirmed an increase in their resistance and productive qualities.
