Abstract

Selenium is an essential element that is involved in numerous physiological processes and accordingly, its inclusion in the feed of both domestic and game animals is advised. The form of selenium affects its bioavailability and the availability of seleno-aminoacids for the synthesis of selenoproteins. As part of the enzymatic system, it participates in thyroid gland metabolism, and plays an important role in the functioning of the antioxidation system. The aim this study was to determine the influence of organic selenium (Selplex®, Alltech, USA) in the amount of 0.5 mg/kg DM in feed mixture on the hematologic and biochemical indicators of fallow deer. The study was conducted on 40 deer over a two- year period. Animals were divided into two groups: young up to 2 years and adults 2-9 years old. The feed mixture was offered for 60 days at the end of the summer season. The trend of increasing the total protein, globulin and immunoglobulin G levels in adult deer fed with a selenium supplement was established, but without significance. The concentration of LDL cholesterol was significantly (P<0.05) higher in adult deer fed selenium supplement. The drop in iron concentrations in the second year is a sign that animals actually received a higher amount of selenium than in the first year. Given that there were no significant differences in the results of hematological and biochemical indicators, re-examination of the normative for the required selenium concentrations as a supplement in the feed mixture is recommended.
