Účinek suplementace anorganické formy selenu u králíků
 VODIČKOVÁ, Lucie
Selenium is one of the most important microelements in the animal organism which acts through selenoproteins. However, both lack and excess have an negative impact on the organism. In this bachelor thesis we focused on the effect of supplementation of the inorganic form of selenium (sodium selenite). The experiment was performed on 18 rabbits of the chinchilla breed at the age of 7-10 months. The rabbits were divided into 3 groups (3 males, 3 females). The control group received the compound feed without added selenium. Group E1 received a feed ration with the addition of selenium at 0,15 mg per kg of dry matter and group E2 with the addition of 4,3 mg per kg of dry matter. In this experiment we deal with the influence of the inorganic form of selenium on the total weight of rabbits and selected organs (liver, kidneys, muscle), the influence of selenium supplementation on its content in these organs and also the influence on selenium content in rabbit blood serum and its effect on blood parameters. The results of our experiment showed histopathological changes only in group E2 in three individuals (50%). In two cases (33%), there were isolated small lymphocytic infiltrates in the interstitium and in one case (17%) the initial phase of glomerulonephrosis. No histological changes were found in the muscle tissue in either case.
