The article considers changes in biochemical blood parameters depending on the degree of adaptation process manifesting on the plantar surface of hind limbs of different sex rabbits and physiological state under cage husbandry technology. Groups of stud bucks (1st series), pregnant and lactating does (2nd and 3rd series of experiments) were formed according to the stages of structural changes depending on the stress of physiological regulatory processes of adaptation (the systematics proposed by R.M. Baevsky). The authors studied the following factors in serum: total protein, protein fractions (albumin, α-, β-, γ-globulin), creatinine, total bilirubin, urea, uric acid, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, glucose triacylglycerol and cholesterol. At the stressed stage of regulatory systems the group of bucks showed a reduction of total bilirubin on the background of decrease of ALT, AST and alkaline phosphatase, which can testify to activation of liver function at this stage, and increase in bilirubin, ALT, AST with a simultaneous decrease in alkaline phosphatase, noted at the overstress stage of physiological adaptation regulatory processes, can testify to decrease in the functional activity of hepatocytes.Pregnant rabbits have the most pronounced compensatory reactions in the third stage of the adaptation process: the increase in absolute and relative γ-globulin values indicates the activation of immune factors. An increase in creatinine and urea levels during the gestation period, against a background of developing adaptive changes on the plantar surface of the feet, indicates a decrease in the filtration capacity of the renal tubules.Lactating animals experience an increased physiological load on the liver, which is expressed by an increase in triacylglycerols throughout the adaptation.
