Abstract
The experiment was conducted at the Animal House, Faculty of Agriculture, Aleppo University, Syria within one year between 2017 and 2018 to determine the effect of organic selenium addition on the digestion treatments of local quail birds and its effect on egg production chains. 35 local mature quail aged 7 weeks old, were randomly distributed to 7 groups (5 birds per group) in the cages. besides the control group with no addition, but 0.3 mg/kg sodium selenite was added to the diets of groups (2, 3, 4 and 5), with the increase of (methionine-vitamin E-fat) in groups (3, 4 and 5) respectively. 0.3 mg/kg of organic selenium (in the yeast) was added to the sixth and seventh groups, and the fat was increased in the seventh group’s diet. In the 22nd week of egg production, the digestion experiment was conducted to calculate digestion factors. The results showed that the dietary parameters that were used did not affect the digestion factor of the dry matter, fiber and protein. The fat digestion coefficient was significantly increased (P≤0.05) when the concentration of vitamin E was increased in the diet. The addition of the organic selenium in the diet with additional concentrations of vitamin E significantly improved (P≤0.05 (the efficiency of the conversion of the digested protein to the egg protein and the performance of the productivity of birds by reducing the periods of interruption in egg production.
