Study of postpartum complications and metabolism disorders in Holstein cows

The object of the study was postpartum complications in cows and metabolites in various pathologies. As a result of the experiment, the problem of early diagnosis of postpartum diseases in cows based on clinical symptoms supported by biochemical blood tests was solved. The results of the study showed that postpartum complications are subclinical ketosis – 22%, hypokalemia – 17%, retained placenta – 16%, subclinical mastitis – 20%, abomasum displacement – 10%, metritis – 8%, gastrointestinal tract disorders – 7%. Cows with subclinical ketosis, mastitis, abomasum displacement, metritis had a high content of β-ketones in the blood. Cows with ketosis had an increased level of cholesterol in the blood. Low cholesterol concentrations were observed in cows with metritis, mastitis, retained placenta. Cows with hypocalcemia had low total blood calcium and Ca/P ratio. Cows had increased β-ketone content and decreased cholesterol content in gastrointestinal disorders. Animals with several pathologies (metritis, subclinical ketosis and mastitis) had increased β-ketone content, decreased total cholesterol, total Ca and Ca/P ratio. The results were obtained due to early diagnosis of postpartum complications in cows, this is explained by daily examination of animals and blood biochemistry studies. The results obtained make it possible to prevent the occurrence of postpartum complications in cows and rapid diagnosis in the first days of occurrence. The conditions for practical application of the proposed diagnosis of postpartum complications are compliance with proper care and appropriate diet for pregnant cows
