The dissertation is devoted the study of day's dynamics of absorption osmotic-active matters by milk gland tissues of cows from flowing blood in accordance with the stages and during a lactation, forming of water-salt phases of milk and its correction. Results were allowed to find day's dynamics of absorption of milk gland tissues of osmotic-active matters in the different stages of lactation, during all lactation periods, forming the water-salt phases of milk by cows. Was proved that absorption of osmotic-active matters by milk gland tissues were decreased from milking till milking during the day. Was detected that absorption of Sodium by milk gland tissues from the first to the third stage of lactation were decreased in 4,32 times (r<0,001), the Potassium and Phosphorus in 1,35 times (r<0,01), the Calcium in 1,51 times (r<0,001), and in 1,21 times of Chlorine (r<0,01). Was established that tissues of milk gland of cows intensively used glucose in accordance with stages of lactation. In the first stage of lactation they absorbed 19,61 % of glucose from flowing blood, 17,46 % in the second and 17,18 % in the third stage of lactation. Other dynamics was established in accordance with use general protein and Magnesium by milk gland tissues. During days from milking to milking the tissues of milk gland as absorbs as secretions a general protein in outflow blood.However, in the stages of lactation a milk gland tissues absorbed a general protein from flowing blood but the Magnesium vice versa in greater degree secretion to outflow blood. The correction ability of milk gland tissues of cows to absorbs the osmotic-active matters from the enriching vitamin-mineral premix ration increase milk production of cows in experimental groups in 4 % and for milk in 1,22 - 1,37 times (r<0,01).
