dc.description.abstractThirty-nine gilts, 82 days old, divided into 3 groups, were fed the main diet supplemented by 0; 0.3 and 0.6 mg Se/kg in the form of Seenriched yeast during 99 days. Selenium levels of 0.3 and 0.6 mg/kg diet led to no significant bodyweight gain nor increase in body mass in any of the studied periods. However, gilts fed a diet supplemented with selenium (0.3 and 0.6 mg/kg) during the whole research period had somewhat higher body mass (1.17 and 3.36%, respectively) and higher average daily bodyweight gain (1.07 and 4.30%, respectively). Selenium supplemented diet influenced also more efficient feed conversion for 3.11 and 2.18%, respectively. The highest content of selenium was observed in the kidneys, then in liver and heart whilst the lowest selenium content was observed in the leg and neck musculature. Selenium concentration in kidneys ranged from 1.23 mg/kg to 1.38 mg/kg and no statistically significant differences were established among studied groups. Selenium concentration in the liver was 3-4 times lower, and in the heart muscle even up to 6 times lower in comparison with the kidneys. Among the studied groups statistically significant differences were established (P lt 0.01) for selenium levels in liver and heart muscle. The highest levels were observed in the group fed 0.6 mg Se/kg diet, that is, in the liver 0.511 mg/kg and in the heart 0.313 mg/kg. Selenium concentration in the leg and neck muscle was twice, i.e., three times higher in gilts fed 0.3 mg Se/kg and 0.6 mg Se/kg diet in relation to animals fed no supplemented selenium diets (P lt 0.01).en
dc.description.abstractTrideset i devet nazimica starih 82. dana, podeljenih u 3 grupe, hranjeno je osnovnim obrokom dopunjenim sa 0, 0,3 i 0,6 mg Se/kg u obliku seleniziranog kvasca u toku 99 dana. Nivoi selena od 0,3 i 0,6 mg/kg hrane nisu doveli do značajnog povećanja prirasta i telesne mase ni u jednom ispitivanom periodu. Međutim, nazimice hranjene obrocima sa dodatkom selena (0,3 i 0,6 mg/kg) u toku celog perioda ispitivanja imale su nešto veću telesnu masu (1,17 i 3,36%, redom) i prosečan dnevni prirast (1,07 i 4,30%, redom). Dodati selen u hranu je uticao i na efikasnije iskorišćavanje hrane za 3,11 i 2,18% redom. Najveći sadržaj selena ustanovljen je u bubrezima, a zatim u jetri i srcu, a najmanji u butnoj i vratnoj muskulaturi. Koncentracija selena u bubrezima kretala se od 1,23 do 1,38 mg/kg i nisu ustanovljene statistički značajne razlike između ispitivanih grupa. U jetri, koncentracija selena je bila 3-4 puta niža, a u srčanoj muskulaturi čak i do 6 puta niža nego u bubrezima. Između ispitivanih grupa ustanovljene su statistički značajne razlike (P lt 0,01) u nivou selena u jetri i srčanoj muskulaturi. Najviši nivo ustanovljen je u grupi hranjene sa 0,6 mg Se/kg hrane i to u jetri 0,511, a u srcu 0,313 mg/kg. Koncentracija selena u butnoj i vratnoj muskulaturi bila je dva, odnosno tri puta veća kod nazimica hranjenih sa 0,3 i 0,6 mg Se/kg hrane u odnosu na grla koja nisu dobijala dodatak selena (P lt 0,01).sr
