Raisbeck et al. (1995) studied the impact of Se on antelope treatment. For a month, antelopes were given water with <50 ppb Se. Following the acclimation one group of antelopes was fed for 168 days with 25 ppm Se native grass hay along with alfalfa hay (0.3 ppm Se). The final exposed Se concentration was of 15 ppm. The control group was given feed with approximately 0.3 ppm Se. After the experiment it was found that the higher exposure to Se caused a reduction in antelopes’ feed intake and a reduction in body weight. However, there were no lung, liver, or kidney abnormalities.
