dc.description.abstract | One hundred and five, one day old unsexed Hybro chickens divided into 7 groups, were fed basal diets supplemented with 0, 2, 5, 10, 20 and 30 mg Se/kg as sodium selenite for 6 weeks. The Se level of 2 mg/kg feed had no effect on chicken daily weight gain. The lowest level at which dietary Se caused reduction in daily gain was 5 mg/kg. Diets supplemented with 10, 15 and 20 mg Se/kg produced 24.5, 62.7 and 96.6% reductions in daily gain, respectively. Lower gains were evident within the first 11 days for chickens fed diets with 20 or 30 mg Se/kg and after 11 days for those provided with 10 or 15 mg Se/kg. Daily gain for the chickens fed the diet with 5 mg Se/kg was significantly lower only in the fifth week of fattening. Feeding diets with 15, 20 and 30 mg Se/kg caused 26.7 60 and 80% mortality, respectively Plasma Se concentrations were increased in all groups given supplementary Se. Maximal plasma Se levels between 220 and 300 mu g/l were reached on the 11th day (except for the group with 2 mg Se/kg) and at that level were maintained to the end of the experiment. | en |
