A comparative analysis of the indicators of biopolymers of connective tissue in the blood serum of healthy foals of all ages, brood-mares and stallions had been conducted. According to the results of clinical research four groups of animals were formed: I group — foals of age 4–6 months, group II — foals of age 1–1.5 years, group III — brood-mares and group IV — stallions.

The blood of these animals was taken to obtain blood serum and its subsequent biochemical analysis. In the blood serum a total protein, cholesterol, urea, creatinine, activity of AST and activity of indicators of biopolymer content in the connective tissue in blood serum, general chondroitinsulfate and glycosaminoglycans fractions were determined.

It has been established significantly that foals aged 4–6 months have higher at 54 % content of total chondroitin (0,17±0,016 g/l). The lowest level of chondroitin was detected in stallions (0,079±0,004 g/l). The level of I fraction GAG — chondroitin-6-sulfate was the same in all groups. The level of II fraction GAG — chondroitin-4-sulfate was significantly lower in foals of age 1–1.5 years. Content of III GAG fractions which contains component of basement membranes in parenchymatous organs heparan sulfate, in foals serum regardless of age was higher than in mares and stallions (P<0.01).

The content of chondroitin sulfates and individual fractions of GAGs in the serum of horses of different age and sex shows the degree of catabolism and synthetic reactions in skeletal tissue and basal membranes of parenchymal organs that occur intensively in foals of age 2–6 months.
