    Abstract: There are so many stressors, like heat, effects the egg production 
  in laying hens. Experiment was conducted in a poultry farm in Bursa. 1730 Hy-Line 
  W77 layer aged 40 weeks assigned to caging unit were used as research materials. 
  Hens were divided into six groups and had different amount of ascorbate supplementation; 
  0, 50, 100, 150, 200 and 250 mg kg<SUP>-1</SUP> feed. Egg production and body 
  weighted were recorded. As result the best ascorbate supplementation to decrease 
  heat stress for this experiment was 100 mg kg<SUP>-1</SUP> feed.
