Changes in lipid metabolism in pregnant sows during the use of lithium ascorbate

The study aims to develop a physiological method for correcting stress and regulating lipid metabolism in pigs. The aim of the work is to develop a new, effective and physiological method to reduce the negative stress impact of any etiology on the processes of ontogenesis and increase productivity. The experiment was conducted on 4 groups of pregnant sows of Irish Landrace breed (3 experimental and 1 control) with 5 heads each. 30 days after the fruitful insemination of the sow, I, II, III groups were daily fed with lithium ascorbate in the form of powder at a dose of 10; 5; 2 mg/kg live weight, respectively. Weighing was carried out before the introduction of the drug. Re-weighing was carried out 2 and 3 months after fertilization and immediately before farrowing. Triacylglycerols, total cholesterol, total protein, lipoprotein fractions – HDL, LDL, and LDL were determined in blood plasma. In the course of the studies it was found that the use of lithium ascorbate feed to pregnant sows at a dosage of 10, 5 and 2 mg/kg body weight, allows to neutralize the negative stress effect and optimize lipid-cholesterol metabolism, which has a beneficial effect on increasing the productivity of pregnant sows. The use of lithium ascorbate in dosages of 10, 5 and 2 mg/kg of live weight allowed to increase the level of HDL in the experimental groups by 43.2; 34.6; 25.7 %, respectively. At the same time in the experimental groups there was a decrease in the concentration of VLDL. So the level of VLDL was lower in the experimental groups by 20.6; 14.7; 5.9 %. The increase in HDL level against the background of LDL reduction indicates a pronounced antiatherogenic effect and a high rate of elimination of free cholesterol from the bloodstream. Introduction, lithium ascorbate on a set of biochemical and physiological parameters confirmed the validity of the proposed concept of the possibility of creating C on its basis of new ways of effective and physiological managementof behavioral reactions and correction of stress.
