The experiment was conducted with Tsigai breed lambs. The diets were composed of concentrates and forage. A concentrate mixture without added Se was provided for control group 1. The mixture supplemented with 0.1 and 0.2 mg Se per kg in the form of sodium selenite was offered to experimental groups 2 and 3, respectively. The highest daily gain was recorded in group 2 (0.239 kg), followed by group 3 (0.221 kg) and control group 1 (0.200 kg). The highest Se contents were found in the kidneys (0.875, 0.985 and 1.194 mg/kg in groups 1, 2 and 3, respectively), followed by the liver (0.146, 0.241 and 0.280 mg/kg in groups 1, 2 and 3, respectively). The lowest Se content were found in heart (0.0723, 0.154 and 0.233 mg/kg in groups 1, 2 and 3, respectively). The differences between the control and the experimental groups were significant. Selenium concentrations ranked in the order kidneys liver heart. The differences between them were significant, as well.
