Influence of liposomal drug on the intensity of proteins oxide modification processes in subclinical mastitis of cows

The article contains the experimental studies of the liposomal drug based on plant raw materials ― hypericum (Hypericum perforatum L.) effect on the intensity of oxidative modification of proteins (OMP) in the blood and milk of cows with subclinical mastitis. Studies have shown that cows with signs of subclinical form of mastitis in the serum have an increase in the content of aldehyde-derived OMP370 and ketone-derived OMP430, respectively, 1.3 and 1.2 times relative to similar indicators in healthy animals. In the milk of sick cows, the content of derivatives OMP370 and OMP430 was1.99 and 2.29 times higher, respectively, than in animals of the control group. At the beginning of the study sick cows’ milk was recorded a significantly low value of the activity of the enzymatic link of antioxidant protection ― superoxide dismutase. At the same time, a 2.6-fold (P
