In the conditions of the Republic of Belarus there was studied the interaction between different types of physical activity, their duration and the reproductive function, milking productivity and age of cows. The research states that the use of a two-month's exercise of non-milking cows in pasture period contributes to extra esturation among 9% of animals, 6,8% growth of the conception rate, decreasing number of cows with stillbirth, mastitis, and endometritis, as well as to the expulsion of afterbirth period. The use of active exercise among young and full-grown caws leads to the shortening of service period and stimulates a milk productivity increase for lactation accordingly on 129 kg and 70 kg. Obtained data of the blood biochemical analysis confirm more active processes of a metabolism which are taking place in animals' organisms at active physical exercise, especially on the carotin mastering from forage which plays a key role in normalization and activization of reproduction processes at female (follicle genes, activization of sexual heat, rut heat and ovulation processes).
