Abstract
The purpose. To study in dynamics of influence of author’s recipes of premixes on hematological indexes of lactating cows. Methods. 2 groups of cows were formed using method of groups-analogs. The control group of animals was fed with premix P60-1; experimental group was fed with a premix based on author’s recipe which removed deficiency of macro- and minor- components in basic diet. Results. Productivity of premixes in feeding lactating cows is proved at disbalance in a ration of minor components and mineral substances. Conclusions. The developed recipe of premixes positively influenced growth power and productivity of cows.

Key words: cow, pregnancy, calving, ration, premix, blood.
