To determine the effects of different levels of supplemental vitamin E on egg production traits, fertility and hatching rate of laying partridges (Alectoris chukar), total 180 partridges were assigned at random to 4 different treatment groups. The treatment lasted 147 d (March-August) in a window closed and natural ventilated environment. Basal diet was supplemented with vitamin E 30, 45, 60 and 75 mg kg(-1) in groups 1 to 4, respectively. Supplemental vitamin E doses improved feed intake, fertility rate and hatching rate.
