Pathogenetic Features Of The Metabolic Syndrome In Black-And-White Cattle (Metabolic Syndrome In Black-And-White Cattle)

This article discusses the issues of changes in clinical, laboratory and instrumental parameters in black-and-white cows with increased body condition. The aim of the study is to establish the relationship between the increased fatness in black-and-white cows and clinical, tonometric, electrocardiographic, echocardiographic, biochemical parameters. The studies were carried out on clinically healthy black-and-white cows during the dry period 60 days before calving. All animals had one completed lactation. The experimental and control groups included cows with a milk yield for the previous lactation> 7500 kg, with a body condition score of> 4.25 points. The control group included clinically healthy cows with a body condition score of 3.0–3.5 points. Clinical, electrocardiographic, echocardiographic, and biochemical parameters were assessed. Increased body condition in black-and-white dairy cows leads to a significant increase in heart rate, systolic, diastolic and mean arterial pressure. In obese black-and-white cows, a significant increase in serum activity of alanine aminotransferase, lactate dehydrogenase and alkaline phosphatase. In black-and-white cows, with an increase in body condition, the cardiovascular system becomes more active, a tendency to the development of arterial hypertension, hepatopathy, and oxidative stress. Control of the body condition score, clinical, electrocardiographic, echocardiographic and biochemical parameters in dairy cows helps to prevent metabolic pathologies. © 2022. Popova et al.
