The use of «bypass soy» in the diets of highly productive cows did not significantly affect on hematological and biochemical parameters of blood. It was marked a slight increase in total protein. The biggest difference (10 g / l) was marked between cows  from the 4th experimental group and control.  In the cows from the 2nd and the 3rd research groups, this figure exceeded the control at  3,1 g / l and 8,1 g / l. It was also marked increasing of albumin fraction in the blood serum of cows from the research groups. This increase in the research groups of cows was 0,5–2,8 g / l compared to control, and α–globulin and β–globulin protein fractions were almost at the level of control. As for γ–globulins, they were more compared with the control in the blood serum of cows from the  3rd, the 4th experimental groups. The biggest difference (3,8 g / l) was marked in cows from the 4th research group.

The concentration of hemoglobin in the blood of cows from the 2nd experimental group was on the level of control and cows from the 3rd and  the 4th experimental groups exceeded the control analogues 10 g / l, or 10,8 % and 13,3 g / l, or 11 %.

Regarding to the red blood cells their number in the blood of experimental cows increased similarly to hemoglobin in the blood of cows from the 4th and the 5th research groups respectively 0,3 and 0,4 Т/ l.

As for the content of white blood cells, there was not found a definite change under the influence of the studied factors.

Increased levels of heavy soluble protein fraction in the cows from the 2nd, the 3rd and the 4th research groups have not given a clear noticeable effect on blood parameters such as alkaline reserve, the concentration of calcium, inorganic phosphorus, sodium and potassium. However, quite a noticeable action was elevated protein levels in catalyses and peroxides activity that apparently contributed to a better oxidation processes in the body.

Volatile fatty acids in the blood of cows from the experimental groups compared with control contained less than that in our opinion, demonstrates their faster assimilation of animals.

Unequal levels of raw protein and bypass protein in the diet caused changes in the concentration of glutathione, which is closely related to the enzyme peroxides. Thus, in the blood of cows from the experimental group increased total content (in mg 3,25–8,59%) and reduced (at 6,66–10,32 mg%) glutathione by reducing the fraction of oxidized glutathione.
