In the conditions of the Republic of Belarus there was analyzed the influence of pasture management and stable and outdoor keeping conditions of dry cows daily behavior and clinical and physiological state, further milk productivity and reproductive capacity. For the experiment there were generated two groups dry cows-analogues - experimental and control one, with 85 heads in each. In course of selection there were considered following parameters: dairy efficiency, age in lactations, terms of start and duration of dry period. Cows of the experimental group during the dry period were on a pasture within light day. Cows of the control group were in sections of rooms in a complex for dry cows with an opportunity of a free entrance to pasture platforms. The state metabolism was observed according to the parameters of serum and plasma of blood. By results of researches it is established, that the pasturable maintenance of dry cows provided more favorable zootechnical and hygienic conditions of the maintenance environment. The conducted tests proved the positive influence of the cows' active exercise in the nonmilking period on the animals' clinicophysiological indices as well as physical and biological character of cervical estruation mucus increasing the readiness of genital organs to impregnation, which contributes to a 5,1% decrease in sickness rate among newborn cows, a 1,5% increase in fertilizing capacity over the next estruation, a 29,5 day reduction of open period, and milk productivity growth.
