The aim of the research is to study the effect of “Phytocomplex S. coronata” supplement on clinical and biochemical status of calves, blood morphology and productivity of dairy cows. The content of ecdysteroids in the additive was determined by highly-efficient liquid chromatography. The experiments were organized in Kirov region. One control and three experimental groups of calves at the age of 1.5 months were selected. Each group included 10 heads. Phytocomplex S. coronata was mixed with water and given to calves for 30 days: group 1 - 10 g, group 2 - 20 g, group 3 - 30 g / calf. Phytocomplex S.coronata was given in the experiment on lactating cows once a day for 60 days: group 1 - 50 g, group 2 - 100 g and group 3 - 150 g / head. Animals in the control were kept on the farm ration without additives. Blood tests of calves (total protein, albumin, ALT, urea, total cholesterol, sublimate test, reserve alkalinity) and cows (erythrocytes, leukocytes, hemoglobin) were carried out at the beginning and at the end of the experiments. It was found that the concentration of ecdysteroids is 500 mg / kg in Phytocomplex S. coronata. The amount of total protein in the blood of calves from the experimental groups increased to 65.7 ± 4.2 - 68.0 ± 2.5 g / l (P   0.05).
