“…1-4). Была установлена прямая умеренная корреляционная связь (r = 0,38) между пониженными параметрами альбуминовой фракции и гемоглобина [12][13][14], а также выявлена положительная корреляция между низкими значениями альбуминов и белкового индекса (r = 0,99, P ˂ 0,001). Помимо этого, регистрировали меньший показатель мочевины (2,8±0,22 ммоль/л при P ˂ 0,001 относительно 1-й группы -7,0±0,82 ммоль/л) и более высокую ПАТОЛОГИЯ ЖИВОТНЫХ, ФАРМАКОЛОГИЯ концентрацию креатинина (102,2±4,93 мкмоль/л относительно 1-й группы -96,5±14,57 мкмоль/л) у коров с большим сроком стельности.…”

Relevance. This work is devoted to the study of prognostic parameters for the development of labor pathology (retention of the placenta), a complication of which is often postpartum endometritis, as well as mastitis in Holstein cows, which will allow us to accurately and timely develop a preventive algorithm of actions.Methods. To solve research problems, animals with different pregnancy periods of the Holstein breed were selected and divided into two groups in the amount of 42 heads: group 1 — cows with a pregnancy period of 5–6 months; group 2 — cows with a pregnancy of 7–8 months. To identify predictors of diseases in the fresh period, the metabolic status of pregnant cows was studied on the basis of clinical and biochemical blood parameters using laboratory methods; the presence or absence of pathologies in these animals was taken into account in the first 10–14 days after calving.Results. Having studied the level of metabolic processes in selected pregnant cows (second and third trimesters), we were able to found that the concentrations of calcium (2.05±0.034 mmol/l), albumin fraction (12.7±2.31%), glucose (2.20±0.299 mmol/l), bilirubin (10.7± 2.94 mmol/l) in animals with a pregnancy of 5–6 months and the values of the protein index (0.17±0.014), phosphorus (2.75±0.215 mmol/l) at 7–8 months of pregnancy are factors predicting the pathology the labor and the postpartum period, namely retention of the placenta, diseases of the mammary gland and endometrium of an inflammatory nature. The most significant was the fact that a decrease in serum calcium and albumin by 18% and 53% in the second and third trimesters of pregnancy increases the likelihood of diseases in newly calved cows by 27–33%.

Relevance. It is known that among cows there is a wide spread of anemia and pathologies accompanied by chronic inflammation. Anemia, like chronic inflammation, leads to disorders that contribute to metabolic changes during pregnancy in cows and have their own characteristics.The aim of the work is to study the effect of pregnancy on carbohydrate and lipid metabolism of cows with anemia syndrome and chronic systemic inflammation.Methods. In the conditions of the livestock complex, studies were conducted on cows (n = 30) of a red-mottled breed with a pregnancy period of 150–160 days. Based on clinical and laboratory examination, the animals were divided into three groups: 1st (n = 15) — healthy, 2nd (n = 8) — with hypochromic microcytic anemia, 3rd (n = 7) — with low-intensity chronic systemic inflammation syndrome. Blood sampling was performed on the 150–160th, 210–220th and 260–265th days of pregnancy to determine the level of total lipids, cholesterol, triglycerides, glucose, lactic and pyruvic acid.Results. The levels of total lipids and glucose have a significant (р ˂ 0.05) inverse and the level of pyruvic acid has a significant direct correlation of noticeable and high strength according to the Chaddock scale with an increase in the duration of gestation in all studied groups. The presence of anemia or chronic systemic inflammation syndrome of low intensity in the transient period creates risks of metabolic failures, which are manifested by a decrease in the intensity of triglyceride deposition by 31.0–34.5% (р ˂ 0.05) and the appearance of a tendency to a negative energy balance.
