The alanin- and aspartataminotransferase (ALT and AST) activities in the liver and oligopeptides concentration in blood were measured in male and female at the age of 1-3 years. Significant age-dependent changes were evidenced, while the sex sex shop differences were not significant. The results can be applied for development of monitoring management and for perspectives of conservation ecology and biodiversity.
