    We studied the effect of feeding the organic selenium on milk somatic cell counts (SCC) in dairy cows, health status of mammary gland, and the increase of selenium content in milk. Selenium was added ... to the premix in form of Sel-Plex (Alltech, Inc.) in the amount 0.2 ppm into 1 kg feed mixture. The enriched mixture was fed to 44 dairy cows during 8 weeks. SCC and selenium content were studied in milk samples and compared with the control group. SCC in milk was 249.7 x 103 ml-1 before the beginning of experiment. SCC decreased from 229.3 x 103 ml-1 to 174.5 x 103 ml-1 (P < 0.001) was noticed with Se feeding from 1st to 8th week of experiment. Se content in milk rose from 0.048 mg l-1 to 0.138 mg l-1 during the experiment, i.e. by 288 % compared with common cow's milk.
