Piven S. Lipid metabolism in cow's organism by lactation periods and gestation of the fetus and its correction

An object is processes of exchange of lipids in the organism of cows after the periods of lactation, their uses for the secretory function of fabrics of mammary gland and for a height and fetation during his gestation. Research aim - to learn conformities to law of exchange of lipids in the organism of cows in connection with the secretory function of mammary gland and period of gestation fetus and to work out the chart of his physiology correction. Methods - physiology, clinical, biochemical, zootechnic, statistical. Novelty - new data of relatively lipid exchange are got in the organism of cows in connection with the secretory function of mammary gland and fetal growth and development during gestation. The presence of two periods of the most intensive use of lipids is set in the organism of cows, by fabrics of mammary gland for secretory and organism of fetus for a height and development: a period of stabilizing of lactation is an early fetal period of gestation. Іt is well-proven that the dynamics of content of basic classes of lipids in the organism of cows-mothers and fetus had opposite character: before completion of seventh month of gestation - prevailed in his blood, and in a fetal period of gestation - in blood of cows-mothers. It is shown that the correction of lipid metabolism in cow's organism during stabilization of lactation and dry periods by means of intramuscular administration of Evitsel and Prodevit drugs and replacement of 20% of concentrates of food ration by sunflower meal, allowed to increase cows' productivity in third experimental group in 554,6±7,82 kg of milk and body weight of calves in 2,60±0,32 kg.
