The paper presents new data on the concentration of testosterone in wild boars (Sus scrofa L.) of various age groups living in the northeast of the European part of Russia (Kirov region). The studies were carried out by the method of enzyme immunoassay using the Immunochem-2100 photometer. The study of seasonal and age-related changes in testosterone level was carried out in adult animals from August to February, in young animals up to a year – from September to December. There was a steady increase in testosterone level from September to November, followed by a decline. The seasonal dynamics of testosterone in adults and young animals up to a year was similar. Significant differences (p<0.05) in the testosterone concentration between adults and young animals were determined. When analyzing the results of the work and comparing them with the results of other researchers, it was found that the testosterone content in the blood of domestic boars and wild boars kept in farm conditions had almost the same dynamics. However, the testosterone levels found in wild boars in our studies are 65.18 % higher than in wild boars subjected to domestication.
