Abstract
To establish the metabolic state using a set of tests that assess carbohydrate, fat, protein, mineral and vitamin metabolism. Among the endemic nature of the disease, characterized by a predominance of primary disorders of mineral metabolism, there are more than 30 such nosology. One of them is osteodystrophy in cattle. In the process of studying this nosology term «osteodystrophy» has undergone a series of transformations in its title: osteomalacia, osteoporosis, osteofibrosis osteopathy, tabes, alimentary osteodystrophy, endemic microelementoses. The unifying criterion is the systemic failure of the entire body with the prevalence of clinically significant changes in bone tissue caused by different reasons, often acting in combination.
