CHANGING IN PROTEIN PROFILE OF PIGS BLOOD DURING FEEDING WITH GM SOYBEANS

. Studies were conducted on the number of pig’s analogues of 24 heads (8 pigs and 4 boars in each group). The diet consisted of 10% of pigs full fat extruded soybean varieties in the control group "Vorskla" (GMO) in the test (GMOs, RR, GTS 40.3.2). There was a significant change in the concentration of protein fractions in the blood of an 8-month pigs fed GM soy: α2 globulin content decreased by 21.54% (p = 0.001), and the amount of γ globulin at 24.33% was higher (p = 0.0005) than in the control, which indirectly indicates a decrease in estrogen levels in the blood of pigs. Changes in the individual indicators characterizing the resistance may further adversely affect the functional activity of the reproductive system of the body of a pig. Thus, by using genetically modified soybeans in diets of pigs, especially those intended for reproduction, it is necessary to monitor the biochemical composition of the blood, in particular the protein profile.
