Короткий опис(реферат):
With the modern method of dairy farming, the significant spread of diseases caused by metabolic disorders remains an urgent problem. Osteodystrophy is particularly common among the latter. The relationship between the content of trace elements in the soil, fodder, and blood of cows with osteodystrophy in an area depleted of biogenic trace elements was established. Early diagnostic indicators of the subclinical course of osteodystrophy in cows are a low serum level of citric acid (147.6–178.5 μmol/l), osteocalcin (0.93–1.28 ng/l), 25(OH)D3 ( 22.1–24.3 nmol/l), retinol (1.10–2.02 μmol/l), tocopherol (7.0–10.0 μmol/l), an increase in total glycosaminoglycans (32.4–41, 2 mg/100 ml), chondroitin sulfates (0.29–0.37 g/l), 30 sialoglycoproteins (2.29–2.97 mmol/l). The use of chelated compounds in cows restores the clinical status and indicators of macro- and microelement exchanges and stabilizes the content of markers of connective tissue metabolism.
