Diagnosis of metabolic disorders in highly productive cows

The research was conducted on the basis of the Saratov State University of Genetics, Biotechnology and Engineering named after N.I. Vavilov and JSC «Plemzavod Trudovoye» (Marksovsky district of the Saratov region). Highly productive cows with clinical signs of diseases caused by metabolic disorders were identified. According to the principle of analogues 2 groups with 60 heads in each were formed. The experimental group of animals with clinical signs of metabolic disorders and the control group with clinically healthy animal. Laboratory tests of blood, urine, and scar contents were performed in cows of the experimental and control groups. Clinical studies have shown that 20% cows of the experimental group have obesity, 23,33% cows - dystrophic phenomena, 28.33% cows - depression, 15.0% cows have visible swelling in the underbelly and lower abdomen. Pododermatitis (1.67%) and skin lesions (6.67%) were recorded in animals. An increase of lymph nodes, changes in the cardiovascular system, the digestive canal, and disorders of the respiratory system were revealed. Dystrophic processes in the bone system were noted. Analysis of the results of clinical and laboratory studies showed that metabolic disorders in the body of highly productive cows are accompanied by clinical manifestations of acidosis, ketosis, osteodystrophy, myocardosis, hepatosis, nephrosis, and an increase in ketone bodies in urine. An improvement of the productive qualities and reproductive health in cows can be achieved only if the metabolic processes in animals are normalized.
