The effect of organic selenium as feed additive contained in the
feed was investigated, applied in concentrations of 0.3 and 0.4 mg Se/kg mixture
on production characteristics pheasant. The study was conducted on a total of 45
common pheasant individuals Phasianus colchicus, six weeks old, divided into
three equal groups of 15 individuals for 60 days. The control pheasants group was
fed with a standard mixture without addition of selenium during the experiment,
while the mixture of group I contained 0.15 g/kg and pheasants group II had 0.20
g/kg additives with organic selenium. The results showed that different amounts of
organic selenium presence in pheasants’ feed had a positive effect on analyzed
productivity indicators of pheasants’ growth rate, both their final body weight and
weight gain (p 0.05). The best production results were achieved by individual II group, which
also had the highest selenium content in muscle tissue of the pectoral muscles,
drumstick and thigh
