The article analyzes the results of clinical research and the state of the indicators of the metabolism of high-yielding cows of PP «AGRO-EXPRESS-SERVICE» in the Mlynivskyi district of the Rivne region due to the lack of biogenic microelements (Co, Cu, Zn).During the clinical examination of cows, the characteristic symptoms of microelementosis (Co, Cu, Zn) were found: loss of appetite, taste distortion, pallor of visible mucous membranes (in 65 cows); rude dull hair; low-elastic skin, subcutaneous fat is not sufficiently expressed; intestinal peristalsis weakened, hypotonic prehistoras. In 95 cows, pulse rate, respiration, scarring and body temperature were on the lower limit of physiological oscillations; only 20.8% of cows had tachycardia (85–95 per 1 minute) and tachypnea (35–45 per 1 minute). In addition, in 45.8% of cows fattening below average, the constitution is dense. The productivity of animals was sharply reduced. In 33.3% of cows, the curvaceousness and shrinkage of wool were noted. In 6.8% of animals, alotriophagia was observed. Due to lack of cobalt in 15% of cows revealed symptoms of osteodystrophy: tight course, convexity of the edges, pain of the joints, softening of the tail vertebrae.The violation of the exchange of Cu, Cu, and Zn in cows was characterized by a decrease in blood serum protein content by 14.8% (P < 0.001), albumin by 28.5%; (P < 0.001), carotene by 33.3%, glucose by 21.4% (P < 0.001), reserve alkalinity by 13.7%, increase in the content of globulins by 14.6% (P < 0.001), bilirubin by 24.6%, creatinine by 17.8% (P < 0.001) and cholesterol by 27.8%.
