The results of pigs’ research of different technological groups (sows, boars-producers, repair young) with the aim of determining of biochemical indexes informativity in serum blood, including the biopolymers of connective tissue, in diagnosis of musculoskeletal systems’ diseases, are represented in the article. It was identified, that the lowering in serum blood the content of chondroitinsulfates, activity of transaminases in boars, which didn’t do the sledge on the phantom, can be the criteria of development of stress myopathy, weakness of ligamentous apparatus and osteochondrosis. The lowering of content in serum blood of chondroitinsulfates and the activity of aspartate aminotransferase in pigs, in which was observed the lameness symptom, can be the criteria not only of weakness of muscles, but and the declining of biosynthesis of proteoglycans of extracellular matrix of joint’s hyaline cartilage, that adducts to osteochondrosis. The declining of body mass, the absence of growth and periodical tremor of pelvic limbs in pigs are going with the increasing in serum blood of the glycoproteins level, a significant decreasing of the transaminase activity, concentration of creatinine and points on the development in pigs of degenerative-dystrophic process in organism and stress myopathy without the injury of joints’ cartilage structure. The using of complex of biochemical researches with the determining of transaminase activity, content of creatinine and, especially, the indexes of connective tissue state – glycoproteins and total chondroitinsulfates in the time of leading of medical examination and survey of pigs in specialized farms we are considering as a perspective.
