In the conditions of the Republic of Belarus the seasonal derangements of metabolic processes at high-producing cows usually take place in the period from March till May. Analysis of efficiency of application of national preparation CMP (complex-mineral preparation -iron (15 mg/ml); iodine (6,8 mg/ml); magnesium (6,0 mg/ml); selenium (0,32 mg/ml) and vitamin preparation Trivitim (vitamin A – 30000 IU; , vitamin D – 40000 IU; vitamin E – 20 mg) for the preserving of high milking yielding capacity and prevention of metabolic processes disorders was realized. Four groups of high productive cows were formed. First group was entered 10 ml of CMP intramuscular; cows of the second group were entered 10 ml of Trivitim intramuscular; cows of the third group were entered CMP and Trivitim in the same doses; and the fourth group was a controlled one. On the 1-st, 7-th and 15-th days there was realized evaluation animal clinical state, hematologic and biochemical blood indexes (leukocytes; erythrocytes; hemoglobin; thrombocytes; ESR; total protein; albumins; urea; creatinine; glucose; calcium; phosphorous; magnesium; iron), and average daily milk yield. There was also analyzed the phagocytic activity of neutrophilic leukocytes. Research results showed that content of leukocytes and ESR in blood in all experimental groups was within the standard limits. In the first experimental group there was state the increasing of hemoglobin (from 91,4 +/- 4,38 up to 111,83 +/- 4,3 g/l (P less than0,05) ) and erythrocytes (from 4,48 +/- 0,21 up to 5,97 +/- 0,45 10E12/l) content. The same changes were stated in cows of the 2-d and 3-d experimental groups. Content of hemoglobin and erythrocyte in blood of cows which were administrated with CMP and Trivitim increased from 90,6 +/- 0,06 to 99,83 +/- 3,61 g/l and from 4,51 +/- 0,27 to 5,55 +/- 0,28 10E12/l, respectively. Analyze of biochemical indexes of cow blood showed that content of total protein, calcium, phosphorus, magnesium and iron increased. On the 15-th day there was stated the decrease of urea. Research results proved that the combined application of CMP and Trivitim was efficient and prevented subclinical disorders of metabolic processes
