The research was realized in the conditions of the Republic of Belarus on a base of joint stock company 'Vasilishki' in Shchuchin district of Grodno region and also in research laboratory of Grodno State Agrarian University. As a result of realized research it was revealed that the pasturable maintenance of dry cows more than stable-extensive housing promoted metabolism normalization in an organism of animals. This was shown by: more optimum clinical and physiological indicators of an organism of dry cows (a pulse rate and breath, the hemoglobin content in erythrocyte, carotin, etc.); decrease in number of cases of newborn calves' disease; a condition of physical and biological properties of the cervical estrus slime specifying in higher readiness of animal genitals to beginning of pregnancy; growth of a daily average milk yield on a cow.
